JP 2001-324934 (page 3-6, Fig. 2)

  However, when a monitor is used as a nameplate, it is difficult to say that a monitor with a message display function alone is sufficiently used, and we want to add functions other than the message display function to further improve convenience. There was a request. In particular, various devices such as intercoms and surveillance cameras are installed around the entrance (around the door) for various functions. When these devices are present independently, it is necessary to perform installation work and maintenance for each device. As a result, there was also a request to simplify the system configuration around the entrance.

  An object of the present invention is to provide a nameplate display device that can simplify the system configuration around the door by providing other functions in addition to the nameplate display function when the display means is used as a nameplate.

In order to solve the above problems, in the invention according to claim 1, display means installed outside the house, display control means for displaying a nameplate on the display means based on display data stored in the storage means, In the nameplate display device, the display means is displayed as a nameplate in a normal state. By touching the nameplate screen, the primary screen is switched from the nameplate screen, and the password input screen is displayed from the primary screen. An authentication means for authenticating the personal identification number when the personal identification number is input on the personal identification number input screen displayed on the screen of the display means instead of the nameplate; when the authenticating means and the personal identification number is correct is determined, and control means for permitting or start the operation of the equipment installed in the housing, the primary screen is displayed on the display means When and, when the primary screen is not operated for a predetermined time, and subject matter to return the display means based on the nameplate screen.
The gist of the invention described in claim 2 is that, when the authentication means determines that the password is not correct, the display control means displays on the display means that the password is incorrect.
In the invention according to claim 3, the display control means forcibly returns the screen of the display means to the nameplate after a predetermined number of mistakes in inputting the personal identification number, and from the screen for a predetermined time. The gist is to make the transition to another screen impossible.
The gist of the invention described in claim 4 is that the device operated by inputting the personal identification number is an entrance door of the house.

To do. The microcomputer 14 can perform data communication with the indoor monitor 10 via the input / output circuit 19. The microcomputer 14 constitutes display control means, control means, and authentication means.

  The microcomputer 14 includes a CPU 20 that executes various controls, a ROM 21 that stores a control program P, a RAM 22 that is used as a work area when the CPU 20 operates, and an EEPROM 23 that stores nameplate data Da. The control program P is a program for operating the outdoor monitor 1 and performs various functions such as an intercom function, a message recording function, a password input function, a visitor recording function, and a recorded video playback function as functions unique to this example. It is a program. The CPU 20 operates based on the control program P in the ROM 21 and executes the various controls described above. The EEPROM 23 corresponds to a storage unit.

  The intercom function is a call function of a communication call facility in which a visitor and a resident make a call between the outdoor monitor 1 and the indoor monitor 10. The microcomputer 14 always displays the nameplate screen 24 shown in FIG. 3 on the display screen 3 in a normal state. When a visitor or the like visits the house 2 and touches the nameplate screen 24, the microcomputer 14 displays the primary screen 25 shown in FIG. 4 on the display screen 3. The primary screen 25 is a screen for executing intercom and password entry. The primary screen 25 is returned to the nameplate screen 24 if there is no touch panel operation for a predetermined time (for example, 60 seconds).

  When the call switch 26 on the primary screen 25 is operated, the microcomputer 14 displays the secondary screen 27 shown in FIG. 4 in which the call switch 26 is activated, and rings a call bell (not shown) in the house 2. To the state. If the resident responds to the call bell within a predetermined time (for example, 20 seconds) and the resident performs a response operation such as lifting the handset with the indoor monitor 10, the microcomputer 14 displays the display screen 3 on the outdoor monitor 1 as shown in FIG. The middle screen 28 is displayed. At this time, the built-in camera 6, the outdoor microphone 7, and the outdoor speaker 8 are in the operating state on the outdoor monitor 1 side, the indoor speaker 12 and the indoor microphone 13 are in the operating state on the indoor monitor 10 side, and the outdoor monitor 1 is connected to the indoor monitor 10. Various data (photographing data, audio data, etc.) can be exchanged between the visitors and the resident. At this time, the image being captured by the built-in camera 6 of the outdoor monitor 1 is displayed on the indoor screen 10 on the indoor monitor 10.

  The microcomputer 14 sequentially monitors the operation of the handset of the indoor monitor 10 and determines that the intercom call should be terminated when the call between the resident and the visitor ends and the handset of the indoor monitor 10 is lowered. Then, the microcomputer 14 restores the display screen 3 of the outdoor monitor 1 from the busy screen 28 (see FIG. 6) to the nameplate screen 24 (see FIG. 3), and the operation of the built-in camera 6, the outdoor microphone 7 and the outdoor speaker 8. To stop the intercom function.

  The message recording function is a function for recording and recording a message (message) while the resident is away. This will be described below. Even if the primary screen 25 is displayed on the display screen 3 of the outdoor monitor 1 and the call switch 26 is pressed, if there is no response for a predetermined time (for example, 30 seconds), the microcomputer 14 is shown in FIG. A tertiary screen 29 is displayed. The tertiary screen 29 is a screen for performing recall, password input, and message input. When the recall switch 30 on the tertiary screen 29 is operated, the microcomputer 14 redisplays the secondary screen 27 on the display screen 3 and rings a call bell in the house 2 to notify the resident that there is a visitor. Try again. The tertiary screen 29 is returned to the nameplate screen 24 if there is no touch panel operation for a predetermined time (for example, 60 seconds).

  Here, when it is determined that the resident is away by repeatedly executing the recall, the visitor operates the message input switch 31 on the tertiary screen 29 to record the message. When the message input switch 31 is operated, the microcomputer 14 displays the recording screen 32 shown in FIG. 8 on the display screen to activate the message recording function. At this time, the microcomputer 14 activates the built-in camera 6, the outdoor microphone 7, and the outdoor speaker 8, records an image during message input with the built-in camera 6, and collects a message sound with the outdoor microphone 7. The microcomputer 14 stores recorded data Db composed of the recorded video and recorded audio in the RAM 22. When the end switch 33 on the recording screen 32 is pressed, the microcomputer 14 ends the message recording function and returns the display screen 3 to the nameplate screen 24.

  When the message recording is performed, the microcomputer 14 transmits history information Dc such as a message recording start date and time to the indoor monitor 10. The indoor monitor 10 displays a list of message recording histories (see FIG. 2) on the indoor screen 11 of the indoor monitor 10 based on the history information Dc. Therefore, the resident can recognize that there was a visitor by looking at the message recording history of the room monitor 10 when he / she comes home, and when the history is selected and executed on the room screen 11, the room monitor 10 Takes in the recorded data Db corresponding to the history from the RAM 22 and reproduces the message on the indoor screen 11.

  The password input function is a function of unlocking the electric lock 35 of the locked entrance door 34 (see FIG. 2) when the password is correct by inputting the password to the outdoor monitor 1 by a touch panel operation. . This will be described below. In the EEPROM 23 of the outdoor monitor 1, personal identification number data Did unique to the outdoor monitor is registered. The personal identification number data Did is not limited to one, but may be plural. A personal identification number setting screen (not shown) is displayed by a touch panel operation on the display screen 3, and an individual code known only to the resident is input together with the personal identification number to be input. In this way, the password is set.

  When the password input switch 36 is operated on the primary to tertiary screens 25, 27, and 29 shown in FIGS. 4, 5, and 7, the microcomputer 14 displays the numeric keypad screen 37 shown in FIG. 9 on the display screen 3. . The numeric keypad screen 37 is a screen for inputting a personal identification number, and includes a numeric keypad switch 38 from 0 to 9, a determination switch 39 to be pressed after the input of the personal identification number is confirmed, and a switch 40 for returning the numeric keypad screen 37 to the primary screen 25. indicate. It should be noted that the numeric keypad screen 37 is returned to the nameplate screen 24 if there is no touch panel operation for a predetermined time (for example, 60 seconds). The numeric keypad screen corresponds to a password input screen.

  When the password is entered by the numeric keypad 38 on the numeric keypad screen 37 and the decision switch 39 is operated after the number is entered, the microcomputer 14 compares the password of itself (outdoor monitor 1) with the input password. It is determined whether or not the input code number is correct. If the microcomputer 14 determines that the input password is correct, it outputs an unlock command signal Xa to the electric lock 35. The electric lock 35 is unlocked based on the unlock command signal Xa, and the entrance door 34 is openable.

  On the other hand, if the input password is wrong, the microcomputer 14 displays the authentication result screen 41 shown in FIG. The microcomputer 14 displays the authentication result screen 41 on the display screen 3 for a predetermined time (for example, 5 seconds). After the predetermined time has elapsed, the numeric keypad 37 is displayed again on the display screen 3 to re-enter the password. Prompt. Here, if the password is entered incorrectly for a predetermined number of times (for example, 3 times), the microcomputer 14 determines that the password entry function should be stopped for safety reasons, and forcibly displays the display screen 3 on the nameplate. By returning to the screen 24, the password input function is forcibly terminated. Then, the microcomputer 14 keeps the display screen 3 in a state incapable of transition from the nameplate screen 24 for a predetermined time (for example, 5 minutes).

  In addition, the visitor recording function has a function that the built-in camera 6 is operated until the display screen 3 returns to the nameplate screen 24 after the switch (for example, the call switch 26 or the password input switch 36 of the primary screen 25) is first operated on the display screen 3. It is a function to record by. This will be described below. When the switch on the display screen 3 is first touched, that is, when the call switch 26 or the password input switch 36 is operated on the primary screen 25, the microcomputer 14 starts recording by the built-in camera 6. To do. The microcomputer 14 stores the recording data Dd in the RAM 22 and ends the recording when the display screen 3 returns to the nameplate screen 24.

  When the visitor recording is performed, the microcomputer 14 transmits history information Dc such as a visitor recording start date and time to the indoor monitor 10 as in the message recording function. The indoor monitor 10 displays a list of recording histories (not shown) on the indoor screen 11 of the indoor monitor 10 based on the history information Dc. Therefore, the resident can recognize that the outdoor monitor 1 has been operated by seeing the recording history of the indoor monitor 10 when returning home, and when the history is selected and executed by the indoor monitor 10, The indoor monitor 10 takes in the recorded data Dd corresponding to the history from the RAM 22 and reproduces the recorded video on the indoor screen 11.

  By the way, recording by the built-in camera 6 is performed in both the message recording function and the visitor recording function, and the relationship is as follows. First, when the message recording function is executed by operating the message input switch 31 on the tertiary screen 29, the recording mode of the built-in camera 6 is switched from the visitor recording function to the message recording function, and the end switch 33 of the recording screen 32 is operated. It becomes the mode to record until it is done. At this time, the recorded data Dd captured before the message recording function operates is erased from the RAM 22.

  FIG. 11 is a configuration diagram showing a schematic configuration of the security system 42. The house 2 is provided with a security system 42 that notifies a resident who has returned home when a third party such as a thief or the like has illegally entered the house 2 while going out, and prevents the resident from entering the house 2 inadvertently. I have. The security system 42 includes a controller 44 that controls locking / unlocking of the entrance door 34 based on wireless communication with the electronic key 43 owned by the resident, and an electrical drive based on commands from the controller 44 to lock the entrance door 34. An electric lock 35 that is in the state or unlocked state and an abnormality monitoring device 45 that performs main control of the system are provided. Note that the controller 44 corresponds to a collation unit, and the abnormality monitoring device 45 corresponds to a determination unit.

  The controller 44 is embedded in the entrance door 34 and includes an antenna 44 a that transmits and receives signals to and from the electronic key 43. When the controller 44 intermittently outputs the request signal Sre from the antenna 44a and receives the ID signal Sid transmitted from the electronic key 43 in response to the request signal Sre by the antenna 44a, the controller 44 obtains the ID code and its own ID code. It is possible to perform ID verification for comparison, and lock and unlock the electric lock 35 on condition that ID verification is established. Further, when the electric lock 35 receives a locking command from the controller 44, a dead bolt (not shown) is popped out by the drive motor to enter a locked state, and when the unlocking command is received from the controller 44, the dead bolt is drawn by the drive motor. It will be unlocked.

  The abnormality monitoring device 45 is attached to an indoor wall or the like, and can communicate with the controller 44 via wiring. The abnormality monitoring device 45 has a push button type warning mode setting switch 45a. After the switch 45a is pressed, the resident who owns the electronic key 43 goes out of the communication area of the antenna 44a and the electric lock 35 is turned on. When in the locked state, the operation mode of the security system 42 is set from the release mode to the alert mode. The abnormality monitoring device 45 is in an operating state when the security system 42 is in the alert mode, and is in a state in which the presence or absence of unauthorized intrusion into the house 2 is sequentially monitored. On the other hand, when the security system 42 is in the release mode, the abnormality monitoring device 45 is deactivated and the operation is stopped.

  In addition to the outdoor monitor 1, the security system 42 includes a detection sensor 46 that detects that a third party has illegally entered the house 2, and a monitoring camera 47 that can photograph the site of the unauthorized entry. . The detection sensor 46 can wirelessly communicate with the abnormality monitoring device 45 (radio wave communication), and the outdoor monitor 1 and the monitoring camera 47 are connected to the abnormality monitoring device 45 via wiring. The detection sensor 46 corresponds to the detection unit, and the monitoring camera 47 corresponds to the photographing unit.

  The detection sensor 46 includes, for example, a door opening / closing sensor 46a that detects unauthorized opening / closing of the window glass 48, an infrared sensor 46b that detects that a person has entered the room, and the door opening / closing sensor 46a is connected to the window glass 48. 46b is installed in each room. In addition to the sensors 46a and 46b, the detection sensor 46 includes, for example, a glass sensor that detects breakage of the window glass 48, an infrared beam sensor that detects entry of a person into the room, and a heat sensor that detects heat. When the detection sensor 46 is in a sensing state (sensor is in an on state), it transmits an unauthorized intrusion detection signal Sa with a unique address of each detection sensor 46 to the outside.

  The monitoring camera 47 is disposed at a position where it is possible to photograph a third party's unauthorized intrusion into the house 2 and is driven and controlled by the abnormality monitoring device 45. The monitoring camera 47 is arranged in pairs with each detection sensor 46. In this example, the monitoring camera 47a installed outdoors for the door opening / closing sensor 46a and the monitoring camera installed indoors for the infrared sensor 46b. 47b. When the monitoring camera 47 receives a shooting start command from the abnormality monitoring device 45, the monitoring camera 47 starts shooting, performs shooting for a predetermined time (for example, 1 minute), and outputs the video data Dx to the abnormality monitoring device 45.

  When receiving the unauthorized intrusion detection signal Sa from the detection sensor 46, the abnormality monitoring device 45 enters an unauthorized intrusion detection state and determines that there has been an unauthorized intrusion in the house 2. At this time, the abnormality monitoring device 45 refers to the unique address given to the unauthorized intrusion detection signal Sa to determine from which detection sensor 46 the unauthorized intrusion detection signal Sa is transmitted, and the destination of the unauthorized intrusion detection signal Sa Then, an imaging start command is output to the surveillance camera 47 that is paired with the detection sensor 46 to image the site of unauthorized intrusion. For example, when receiving the unauthorized intrusion detection signal Sa from the door opening / closing sensor 46a, the abnormality monitoring device 45 causes the monitoring camera 47a to perform imaging, and when receiving the unauthorized intrusion detection signal Sa from the infrared sensor 46b, performs imaging to the monitoring camera 47b. Make it.

  Upon receipt of the unauthorized intrusion detection signal Sa from the detection sensor 46, the abnormality monitoring device 45 outputs an abnormality occurrence signal Sb to the controller 44 in synchronization with the monitoring camera 47 starting shooting, and there is an unauthorized entry into the house 2. This is notified to the controller 44. When the controller 44 receives the abnormality occurrence signal Sb, the controller 44 is in a restricted state in which the electric lock 35 cannot be freely locked and unlocked. In this restricted state, even if ID verification is established between the electronic key 43 and the controller 44, the controller 44 is locked. The electric lock 35 in the state is not unlocked.

  Here, the recorded video playback function is a function for broadcasting the recorded video captured by the monitoring camera 47 on the outdoor monitor 1 when the resident returns home. This will be described below. The outdoor monitor 1 is driven and controlled by the abnormality monitoring device 45 and operates based on various commands received from the abnormality monitoring device 45. The outdoor monitor 1 always operates regardless of the operation mode of the security system 42, and displays the nameplate 4 on the display screen 3 in the normal state. When the controller 44 recognizes that ID verification is established when the controller 44 is in the restricted state and the electric lock 35 is locked, the controller 44 outputs an ID verification establishment signal Sc to the abnormality monitoring device 45. When the abnormality monitoring device 45 receives the ID verification establishment signal Sc from the controller 44 when the device itself is in an unauthorized intrusion detection state, the abnormality monitoring device 45 outputs a reproduction start signal Sd to broadcast the video data Dx captured from the monitoring camera 47 on the outdoor monitor 1. Output to the outdoor monitor 1.

  The abnormality monitoring device 45 outputs a regeneration start signal Sd to the outdoor monitor 1 to display an initial regeneration screen 49 shown in FIG. 12 on the outdoor monitor 1 instead of the nameplate screen 24 (see FIG. 2). The reproduction initial screen 49 displays a list of detection sensors 46 that have detected unauthorized intrusion. The outdoor monitor 1 can select a recorded video to be broadcast on the outdoor monitor 1 by touching the display unit 50 of the detection sensor 46. When the display unit 50 is pressed, the abnormality monitoring device 45 displays a simplified diagram 51 of the house 2 shown in FIG. 13 on which the position of the detection sensor 46 is simultaneously displayed on the outdoor monitor 1, and then displays the selected detection sensor 46 on the selected detection sensor 46. The corresponding video data Dx is sent to the outdoor monitor 1, and an illegal intrusion video is broadcast on the display screen 3.

  When a resident who does not have the electronic key 43 comes home, the personal identification number is input on the outdoor monitor 1 to unlock the electric lock 35. At this time, the abnormality monitoring device 45 inputs the unlock command signal Xa from the outdoor monitor 1, but if it is an unauthorized intrusion detection state, the abnormality monitoring device 45 receives the regeneration start signal Sd as in the case of using the electronic key 43. Output to 1. Accordingly, the outdoor monitor 1 displays the reproduction initial screen 49 shown in FIG. 12 in place of the nameplate screen 24, so that the recorded video of unauthorized intrusion can be reproduced.

  The outdoor monitor 1 includes a push button type release switch 1a that releases the controller 44 in the restricted state to the normal state. When the release switch 1a is pressed, the outdoor monitor 1 outputs a release command signal Se to the abnormality monitoring device 45. When receiving the release command signal Se from the outdoor monitor 1, the abnormality monitoring device 45 determines that the restricted state of the controller 44 should be released, and outputs a release permission signal Sf to the controller 44. When the controller 44 inputs the release permission signal Sf when the controller 44 is in the restricted state and the electric lock 35 is in the locked state, the controller 44 unlocks the electric lock 35 on the condition that ID verification is established at that time.

Next, the operation of the outdoor monitor 1 of this example will be described.
First, a case where a visitor visits the house 2 will be described. At this time, when the display screen 3 of the outdoor monitor 1 is touched by a visitor, the primary screen 25 shown in FIG. When the call switch 26 on the primary screen 25 is operated, the secondary screen 27 shown in FIG. 5 is displayed on the display screen 3 and a visitor may be visited by ringing a bell in the house 2. A resident in the house 2 is notified. When the resident lifts the handset of the indoor monitor 10 in response to the call bell, the intercom function operates, and the visitor and the resident can talk between the outdoor monitor 1 and the indoor monitor 10.

  When the interphone is used, the in-call screen 28 shown in FIG. 6 is displayed on the outdoor monitor 1, and the video captured by the built-in camera 6 is broadcast on one indoor monitor 10. When the telephone call is finished and the handset of the indoor monitor 10 is lowered, the outdoor monitor 1 returns to the nameplate screen 24. The return from the busy screen 28 to the nameplate screen 24 is not limited to the condition that the handset of the indoor monitor 10 has been lowered. For example, a predetermined time (after the outdoor monitor 1 becomes the busy screen 28) For example, the display of the outdoor monitor 1 is switched, but the intercom is maintained in a state in which a call can be made.

  If there is no response even if the call switch 26 is operated on the primary screen 25 and a call is made, the tertiary screen 29 shown in FIG. 7 is displayed on the outdoor monitor 1, and the recall switch 30 is displayed on the tertiary screen 29. When is operated, the outdoor monitor 1 switches to the secondary screen 27 again and the recall is executed. If there is no response from the house 2 even if the recall is made in this way, the outdoor monitor 1 returns to the state where the tertiary screen 29 is displayed again, and if the recall is repeated, the outdoor monitor 1 The operation of switching the display between the secondary screen 27 and the tertiary screen 29 is repeated.

  When there is no response even after recall, when the message input switch 31 on the tertiary screen 29 is operated by a visitor to leave a message, the message recording function operates, and the recording screen 32 shown in FIG. Is displayed on the outdoor monitor 1. At this time, the built-in camera 6 performs a recording operation and the outdoor microphone 7 performs a sound collecting operation until the end switch 33 of the recording screen 32 is operated. When a message is issued from a visitor, the message is recorded by the built-in camera 6 and the outdoor microphone 7, and the recorded data Db is stored in the RAM 22. Here, the end of the message recording is not limited to the operation of the end switch 33 on the recording screen 32, but may be a condition that, for example, a predetermined time (for example, 60 seconds) elapses to forcibly end the message recording. Good. When the message recording function ends, the display on the outdoor monitor 1 returns to the nameplate screen 24.

  When a message is recorded on the outdoor monitor 1, the message recording history is displayed on the indoor monitor 10. Accordingly, the resident who has returned home can recognize that there was a visitor by displaying the history on the indoor monitor 10, and can check the message by selecting and executing the message recording history of the indoor monitor 10. The message reproduction on the indoor monitor 10 is performed by selecting and executing message recording history based on the touch panel operation of the indoor monitor 10, capturing the recording data Db corresponding to the selected execution from the RAM 22, and reproducing it. Done.

  The outdoor monitor 1 starts the operation of the visitor recording function when a visitor or the like first touches the switch on the display screen 3 and records the visitor with the built-in camera 6. This visitor recording function is a function different from the message recording function described above, and is a function for recording visitors who do not record messages on the outdoor monitor 1. If a visitor recording function is provided, it is possible to record a visitor who has not recorded a message, for example, an operator who operates the outdoor monitor 1 for the purpose of mischief, and is effective in preventing unauthorized operation of the outdoor monitor 1 and the like. There is.

  When the switch of the outdoor monitor 1 is first touched, that is, when the call switch 26 or the password input switch 36 is operated on the primary screen 25, recording by the built-in camera 6 is started. This recording is performed until the display screen 3 of the outdoor monitor 1 returns to the nameplate screen 24, and this recording data Dd is stored in the RAM 22. When recording is performed by the built-in camera 6 with the visitor recording function, the recording history is displayed on the indoor monitor 10. Accordingly, the resident who has come home can recognize that the outdoor monitor 1 has been operated by the history display on the indoor monitor 10, and can confirm the recorded video by selecting and executing the recording history of the indoor monitor 10. The recording history is reproduced in the same manner as the message history.

  Subsequently, a case where the resident returns to the house 2 will be described. When all the residents go out and leave the house 2, the residents press the warning mode setting switch 45a of the abnormality monitoring device 45, and the security system 42 is set to the operation standby state. When the resident moves out by opening and closing the entrance door 34 after the switch operation and the resident with the electronic key 43 goes out of the communication area of the antenna 44a and the electric lock 35 is locked, an abnormality is monitored as shown in FIG. The device 45 sets the security system 42 to the alert mode, and monitors unauthorized third parties entering the house 2. In this state, the abnormality monitoring device 45 is in a state in which a signal from the detection sensor 46 can be received, and the monitoring camera 47 is in an operation standby state.

  Here, it is assumed that the resident who owned the electronic key 43 returned home in a state where the security system 42 did not detect unauthorized intrusion. In this case, when the resident enters the communication area of the antenna 44 a, the controller 44 performs ID verification with the electronic key 43. Here, since the controller 44 is in a normal state (that is, an unrestricted state), if the ID collation is established between the controller 44 and the electronic key 43, the electric lock 35 is unlocked. Accordingly, the entrance door 34 is unlocked, and the resident can open the entrance door 34 and enter the house 2 as usual.

  Further, it is assumed that a resident who does not own the electronic key 43 returns home in a state where the security system 42 has not detected unauthorized intrusion. In this case, the resident operates the outdoor monitor 1 at the entrance, and displays a numeric keypad screen 37 shown in FIG. When the decision switch 39 is operated after the password is entered on the numeric keypad screen 37 by the resident, the microcomputer 14 determines whether or not the entered password is correct.

  Since the resident should know the correct personal identification number, the input personal identification number should be correct. When the input personal identification number matches that on the outdoor monitor 1, the unlock command signal Xa is sent from the outdoor monitor 1. It is output to the abnormality monitoring device 45. When the abnormality monitoring device 45 inputs the unlock command signal Xa, a release permission signal Sf is output from the abnormality monitoring device 45 to the controller 44 in response thereto. When the controller 44 inputs the release permission signal Sf, the controller 44 unlocks the electric lock 35. Accordingly, the entrance door 34 is unlocked, and the resident can open the entrance door 34 and enter the house 2. When the unlocking of the electric lock 35 is completed, the controller 44 outputs an unlocking completion signal Sg (see FIG. 11) indicating that the unlocking has been completed to the abnormality monitoring device 45. When the abnormality monitoring device 45 receives the unlocking completion signal Sg, the abnormality monitoring device 45 releases the warning mode based on the signal, and switches the operation mode of the security system 42 to the release mode.

  On the other hand, when the security system 42 is in the alert mode, it is assumed that the thief attempts an unauthorized entry into the house 2. If the thief opens the window glass 48 illegally and the door opening / closing sensor 46a detects this, the door opening / closing sensor 46a transmits an unauthorized intrusion detection signal Sa as shown in FIG. Further, when the theft goes into the house 2 and the infrared sensor 46b detects this, the infrared sensor 46b also transmits an unauthorized intrusion detection signal Sa. In this example, both the door opening / closing sensor 46a and the infrared sensor 46b are in a sensing state, and an unauthorized intrusion detection signal Sa is transmitted.

  When receiving the unauthorized intrusion detection signal Sa, the abnormality monitoring device 45 enters an unauthorized intrusion detection state, determines that a theft has entered the house 2 and outputs an imaging start command to the surveillance camera 47, and enters the surveillance camera 47. Have the scene shot. Then, the abnormality monitoring device 45 takes in the video data Dx photographed by the monitoring camera 47 and stores it in the internal RAM. In this example, since the intrusion is detected by both the door opening / closing sensor 46a and the infrared sensor 46b, the abnormality monitoring device 45 outputs a shooting start command to both the monitoring cameras 47a and 47b, and the two monitoring cameras 47a. , 47b, the unauthorized intrusion site is photographed.

  When the abnormality monitoring device 45 receives the unauthorized intrusion detection signal Sa, the abnormality monitoring device 45 outputs an abnormality occurrence signal Sb to the controller 44 in synchronization with the intrusion site shooting by the monitoring camera 47. When the controller 44 inputs the abnormality occurrence signal Sb, the controller 44 determines that a thief has illegally entered the house 2 and enters a restricted state where the electric lock 35 cannot be freely unlocked. In this restricted state, even if the resident who owns the electronic key 43 comes home after the electric lock 35 is locked out, and the ID verification is established between the electronic key 43 and the controller 44, the controller 44 is The lock 35 is maintained in the locked state and is not unlocked.

  Here, when the resident who owns the electronic key 43 comes home after the security system 42 detects unauthorized intrusion, when the resident who owns the electronic key 43 enters the communication area of the antenna 44 a, the controller 44 controls the electronic key 43. ID collation with Here, since the controller 44 is in a restricted state, the electric lock 35 is not unlocked even if ID verification is established between the controller 44 and the electronic key 43. Accordingly, since the resident cannot enter the house 2 and is not unlocked although the electric lock 35 is supposed to be locked, the resident knows that the theft has entered the house 2 and enters the house 2 carelessly. Disappear.

  When the ID collation is established in the restricted state, the controller 44 does not permit the unlocked electric lock 35 to be unlocked and outputs an ID collation establishment signal Sc to the abnormality monitoring device 45. When the abnormality monitoring device 45 inputs the ID verification establishment signal Sc in the unauthorized intrusion detection state, the abnormality monitoring device 45 outputs a regeneration start signal Sd to the outdoor monitor 1. When the outdoor monitor 1 receives this playback start signal Sd, the recorded video playback function is activated, and an initial playback screen 49 (see FIG. 12) is displayed on the outdoor monitor 1 instead of the nameplate screen 24. When unauthorized intrusion is detected by both the door opening / closing sensor 46a and the infrared sensor 46b as in this example, these two sensor names are displayed on the reproduction initial screen 49.

  Then, when the resident touches the display unit 50 of the video to be broadcasted among the display units 50 of the detection sensors 46 displayed on the outdoor monitor 1, the playback video is selected on the outdoor monitor 1. Then, a simplified diagram 51 (see FIG. 13) showing where the detection sensor 46 is located in the house 2 is reproduced on the outdoor monitor 1, and then an image taken by the monitoring camera 47 that forms a pair with the detection sensor 46. Is reproduced on the outdoor monitor 1. Accordingly, by watching the video broadcast on the outdoor monitor 1, the resident can confirm what the reaction cause of the detection sensor 46 is, and can recognize how the unauthorized entry has been made from which place in the house 2. It becomes possible.

  On the other hand, even when the detection sensor 46 reacts and the photographing by the monitoring camera 47 is performed, for example, a ball or the like hits the window glass 48 and the door opening / closing sensor 46a reacts due to the shaking, to the house 2. The security system 42 may operate without causing unauthorized intrusion. In this case, if the resident who came home sees the playback video of the outdoor monitor 1, it can be seen that the electric lock 35 is in a restricted state, not due to unauthorized intrusion, so the resident checks the outdoor monitor 1 and enters the house 2. If it is determined that there is no abnormality, the release switch 1a of the outdoor monitor 1 is pushed.

  Then, the outdoor monitor 1 outputs a release command signal Se to the abnormality monitoring device 45. When the abnormality monitoring device 45 inputs the release command signal Se from the outdoor monitor 1, the operation mode of the security system 42 is switched to the release mode, and the controller The release permission signal Sf is output to 44. When the controller 44 inputs the release permission signal Sf when the electric lock 35 is locked and the electric lock 35 is locked, the controller 44 determines whether or not ID collation is established with the electronic key 43 at that time, and the ID If the verification is established, the electric lock 35 is unlocked. Accordingly, since the resident confirms the safety in the house 2 and enters the house 2 with 35 electric locks, the resident can enter the house 2 after confirming the safety in the house 2.

  In addition, when a resident who does not own the electronic key 43 returns after the security system 42 detects an unauthorized intrusion, the resident operates a display operation on the outdoor monitor 1 at the front door, and performs a password to unlock the electric lock 35. A numeric keypad screen 37 shown in FIG. 9 is displayed on the display screen 3 to input a number. When the decision switch 39 is operated after the password is entered on the numeric keypad screen 37 by the resident, the microcomputer 14 determines whether or not the entered password is correct.

  If the password input person is a resident, the password should be correct. If the input password matches that of the outdoor monitor 1, the unlock command signal Xa is output from the outdoor monitor 1 to the abnormality monitoring device 45. . When the abnormality monitoring device 45 inputs the unlock command signal Xa, a release permission signal Sf is output from the abnormality monitoring device 45 to the controller 44 in response thereto. Here, if the controller 44 is in the restricted state, the electric lock 35 is not unlocked even if the release permission signal Sf is input. Accordingly, since the resident does not enter the house 2 and is not unlocked although the electric lock 35 is unlocked, the resident knows that the theft has entered the house 2 and enters the house 2 carelessly. Disappear.

  Further, when the unlocking command signal Xa is input, the abnormality monitoring device 45 outputs a reproduction start signal Sd to the outdoor monitor 1 in the same manner as when the electronic key 43 is used in the unauthorized intrusion detection state, and displays on the nameplate screen 24. Instead, the reproduction initial screen 49 is displayed on the outdoor monitor 1. As in the case of using the electronic key 43, when the recorded video to be reproduced is selected and executed on the outdoor monitor 1, the recorded video is reproduced on the outdoor monitor 1. Accordingly, even when the resident enters the room by performing the password input operation on the outdoor monitor 1, the resident can check how the unauthorized intrusion has occurred from which place in the house 2.

  Then, after confirming the recorded video, if it is determined that there is no abnormality in the house 2, the release switch 1a is pushed by the resident. Then, the abnormality monitoring device 45 inputs the release command signal Se from the outdoor monitor 1, thereby switching the operation mode of the security system 42 to the release mode and outputting the release permission signal Sf to the controller 44 to release the electric lock 35. Lock it. Therefore, even if the resident enters the house 2 by the password input operation, after confirming the recorded video of the surveillance camera 47 with the outdoor monitor 1, the electric lock 35 is unlocked and the house 2 is entered. It becomes possible to enter the house 2 after confirming the safety in the house 2.

  In this example, the outdoor monitor 1 used as the nameplate 4 in a normal state is shared as a monitor for various functions such as an intercom function, a message recording function, a personal identification number input function, a visitor recording function, and a recorded video reproduction function. . Accordingly, since the outdoor monitor 1 is used for multi-function, it is possible to reduce the number of monitors compared to the case where a monitor is prepared for each function, and the system configuration around the entrance (around the entrance door 4) is simple. Various effects, such as simplification, simplification of monitor wiring work, and cost reduction required for monitoring, are obtained.

According to the configuration of the above embodiment, the following effects can be obtained.
(1) The outdoor monitor 1 is shared as a monitor for various functions such as a nameplate display function, an intercom function, a message recording function, a password input function, a visitor recording function, and a recorded video reproduction function. Accordingly, the outdoor monitor 1 becomes multi-functional, and the number of monitors can be reduced as compared with the case where a monitor is prepared for each function, and the system configuration around the entrance (around the entrance door 4) is simplified. Various effects such as simplification of monitor wiring work and cost reduction for monitoring can be obtained.

  (2) When the outdoor monitor 1 is used as an interphone, the call-in-progress screen 28 is displayed on the display screen 3 of the outdoor monitor 1, so that the visitor recognizes that the intercom call can be executed. Can do. Even when the message recording function is executed on the outdoor monitor 1, the recording screen 32 is displayed on the display screen 3, so that the visitor can recognize that the message is being recorded.

  (3) When the outdoor monitor 1 is used as an interphone, the display screen 3 of the outdoor monitor 1 returns to the nameplate screen 24 when the interphone call ends, so that the visitor can recognize that the interphone has ended. .

  (4) Since the outdoor monitor 1 is equipped with the visitor recording function, recording by the built-in camera 6 is performed from the time when the switch of the outdoor monitor 1 is first touched. Therefore, the resident can confirm the person who operated the outdoor monitor 1 with the recorded video, and can identify the person who operated the outdoor monitor 1 for the purpose of mischief. The recording by the visitor recording function ends when the display screen 3 of the outdoor monitor 1 returns to the nameplate screen 24. Therefore, when the display screen 3 returns to the nameplate screen 24, since there is a high probability that there is no person in front of the outdoor monitor 1, recording by the built-in camera 6 can be terminated at a suitable timing.

  (5) When the password input function is executed on the outdoor monitor 1, if the password is not correct, an authentication result screen 41 indicating that is displayed on the outdoor monitor 1, so that the password is recognized to be incorrect. can do. In addition, if the wrong input of the security code continues for a predetermined number of times, the display screen 3 of the outdoor monitor 1 is forcibly returned to the nameplate screen 24, and the display screen 3 cannot be shifted from the nameplate screen 24 for a predetermined time. Therefore, it is highly likely that an unauthorized intruder has operated the wrong PIN number many times, and if the PIN number is incorrectly entered many times, the PIN number can be changed so that it cannot be changed to another screen. Input itself is prohibited, and high security can be secured.

  (6) When the security system 42 detects an unauthorized entry into the house 2, the unlocking of the locked electric lock 35 is restricted, and the electric lock 35 is unlocked even if the ID verification of the electronic key 43 is established. It will be unlocked. Accordingly, the resident cannot open the entrance door 34, and it is possible to prevent the resident from inadvertently entering the house 2 where a third party such as a theft may be present, and to ensure the security of the resident. Can do. Also, since the video taken by the monitoring camera 47 when the security system 42 detects an unauthorized intrusion is broadcast on the outdoor monitor 1 when the resident returns home, it is confirmed how and where the unauthorized intrusion occurred. And theft can be dealt with quickly and accurately.

  (7) When the security system 42 detects an unauthorized intrusion, both the unlocking of the electric lock 35 and the unauthorized entry site on the outdoor monitor 1 are broadcasted. The residents can be notified more reliably.

  (8) When a monitoring camera 47 is installed so as to form a pair with each detection sensor 46, and a plurality of detection sensors 46 detect unauthorized intrusion, an image of an unauthorized intrusion site corresponding to each detection sensor 46 is monitored outdoors. 1, each can be aired. Therefore, unauthorized intrusion can be monitored over a wide area of the house 2, and the security of the security system 42 can be improved.

  (9) When a plurality of detection sensors 46 detect unauthorized intrusion and the unauthorized surveillance site is photographed by a plurality of monitoring cameras 47, it is possible to select an image to be broadcast on the outdoor monitor 1 by operating the outdoor monitor 1 with a touch panel. Therefore, the resident can freely select the video to be broadcast on the outdoor monitor 1.

  (10) When the alarm mode setting switch 45a of the abnormality monitoring device 45 is pressed, the security system 42 is set from the release mode to the alarm mode, and the intrusion into the house 2 is monitored. Therefore, when there is a resident in the house 2 normally, if the operation mode of the security system 42 is set to the release mode, a situation in which the resident is apologized and the resident is detected as a theft is less likely to occur, and the usability as a system is improved. .

  (11) When the locked electric lock 35 is in the restricted state, when the release switch 1a of the outdoor monitor 1 is pressed, the electric lock 35 is unlocked on the condition that the ID verification of the electronic key 43 is established, and the security system 42 returns to the release mode. Therefore, the resident himself can reset the security system 42 and the system is highly versatile.

In addition, you may change the said embodiment not only to the said structure but to the following aspects.
