[Functions and operations according to the first embodiment]
Next, functions and operations of crime prevention and crime deterrence according to the first embodiment will be described. In order to display at least the face image of the visitor imaged by the video camera 30 which is the imaging means in the child device 1 for the crime deterrence, in order to display the child monitor 31 in advance, by the keyboard 7 operation in the parent device 1, (a) When a person in front of the dwelling unit (including a visitor) approaches the video camera 30 of the slave unit 1 to some extent, the person detection sensor 26 detects it, and the video camera 30 starts imaging with the detection signal. Recording image data and audio data in the recording unit 8 or (b) When the call button 27 of the handset 2 is pressed, the video camera 30 starts imaging with the signal and the image data and audio data are recorded in the recording unit 8. Either one or (c) both modes are selected. Here, both modes are modes in which imaging and recording are preferentially started when the call button 27 is pressed regardless of whether a visitor is detected by the human sensor 26. Accordingly, when the call button 27 is pressed before detecting the visitor (person in front of the dwelling unit) by the human detection sensor 26, imaging and recording are started. Even when the sensitivity is poor, the visitor's image data and audio data are completely stored.

  The main control unit 3 controls to display the visitor's image on the child monitor 31 in accordance with these three selections. Therefore, in any of the above three aspects, the captured face image of the visitor is displayed on the child monitor 31, so that the crime deterrence is enhanced.

  That is, when there are many occurrences of mischief with respect to the handset 2 or outside the entrance, or when there is a fear of mischief, imaging by the video camera 30 is started by detection of a visitor by the human sensor 26 according to a preset setting, and the child monitor Since the image of the visitor can be displayed in 31, the person in the room (for example, a woman or an elderly person) can talk to the malicious visitor without having to talk or question directly with the visitor. Thus, it is possible to strongly recognize (recognize) that the face (image) of the user is reflected on the child monitor 31 and recorded on the recording unit 8. As a result, it is possible to effectively deter illegal acts and crimes such as tampering and damaging objects after that.

  On the other hand, pressing the call button 27 may trigger the start of imaging and recording. If the parent monitor 10 of the parent device 1 can confirm that the person who pressed the call button 27 is a bona fide visitor (for example, an acquaintance or family member), the imaging operation of the video camera 30 is performed by the keyboard operation in the parent device 1. In addition, control may be performed so that the recording is terminated. If the person who pressed the call button 27 pretends to be a bona fide visitor (like an outsider such as a malicious visitor seller), the imaging operation and recording will not end until a predetermined time has elapsed. In this way, crime prevention can be improved.

  Furthermore, the child monitor 31 can be configured to display character data for requesting a predetermined input to the numeric keypad 25 when the call button 27 is pressed. That is, when a devoted visiting seller or the like presses the call button 27 to call a person in the room despite the display of his / her image on the child monitor 31, one of the display screens of the child monitor 31 is displayed. The character data for requesting a predetermined input (input of a personal identification number or the like) to the numeric keypad 25 in the handset 2 is displayed on the whole or the whole, or the above-mentioned matters are voiced on the speaker 33 of the child monitor 31. The requested voice can be output. As a result, if the input data (password) is different, “The input data is different. For example, a character display such as “Please input again” is displayed on the child monitor 31 so as not to give an opportunity for the person in the room and the visitor to have a direct conversation, thereby improving the crime prevention performance.

  The master unit 1 further includes an emergency push button (one key of the keyboard 7 may correspond to the emergency push button), and when the emergency push button is pressed, the main control unit 3 The speaker 33 in the machine 2 can be controlled to output an emergency sound. With this configuration, when the call button 27 is pressed down deliberately, or when a random input operation is repeated on the numeric keypad 25, the person in the room presses the emergency push button provided in the base unit 1. When the user presses down and causes the speaker 33 in the handset 2 to generate an emergency sound with a predetermined high output, it is possible to inform the neighbors that the nuisance is in progress. As a result, the cooperation of neighbors can be easily obtained, and the crime prevention performance is greatly improved.

  It should be noted that when the captured image of the video camera 30 is displayed on the parent monitor 10, a plurality of types of tones of the neglected sound generated by the speaker 12 of the parent device 1 depending on whether the person detection sensor 26 or the call button 27 is used. It is possible to select a command by using the keyboard 7 of the base unit 1 or the like, such as changing to a silent state or setting a silent state.

  Further, after the image data captured by the video camera 30 and the audio data from the microphone 32 are stored in the recording unit 8 for a certain period, the main control unit 3 erases the old data in the recording unit 8 in order from the oldest data. Is to control. Thereby, there is an effect that recent data can be stored (saved) for a certain period without increasing the recording capacity of the recording unit 8 in a dark manner.

[Second Embodiment of Security Device]
In the second embodiment, the master unit 1 'and the slave unit 2' having the above-described configuration are applied to a collective building 35 such as an apartment.

  That is, as shown in FIG. 2, each dwelling unit 36 of the collective building 35 is provided with a parent device 1 ′ and a child device 2 ′. The management controller 37 for the collective building is connected to the master unit 1 ′ of each dwelling unit 36 through a communication network 38.

  The basic configuration, functions, and operations of the master unit 1 ′ and the slave unit 2 ′ are the same as those in the first embodiment (FIG. 1). Accordingly, the same components are denoted by the same reference numerals and detailed description thereof is omitted. The management controller 37 and the master unit 1 'are connected to the communication line network 38 via the PLC adapter 40 (41) provided in each. The communication line network 38 in this embodiment is a so-called high-speed power line communication line (Power Line Communications), and employs a communication technology that sends information signals on power lines. Note that the management controller 37 may be installed in a management unit far from the apartment building and connected via an Internet network (communication network).

  Accordingly, the functions and actions described in the first embodiment increase the crime deterrence in each dwelling unit in an apartment building such as a condominium. Further, if the situation occurring in one dwelling unit 36 is immediately notified to the entire apartment building via the management controller 37, the security performance of the entire apartment building is improved.

  The emergency broadcast data refers to where the dwelling unit 36 is located by pressing the emergency push button in the keyboard of the master unit in the dwelling unit 36 where the nuisance is in progress, in addition to the above-mentioned breaking news such as earthquake and fire. For example, specific contents such as “A nuisance is occurring in the room XX on the floor ○”.

  Necessary data recorded in the recording unit 8 of the master unit 1 ′ for each dwelling unit 36 is transferred to the recording unit of the management controller 37. Therefore, even if the recording unit 8 in the master unit 1 ′ of each dwelling unit is destroyed after recording the necessary data, or even if the data cannot be reproduced due to a failure, the necessary data is not stored in the recording unit of the management controller 37. Because it remains, it can be surely useful for later crime proofs.

  Further, if the emergency broadcast data is incorrect, the management controller 37 is connected to the main control means in each master unit 1 'by a communication network, and each master unit indicates that the emergency broadcast data is incorrect. Playback is possible on the speakers 12 and 33 or the external speakers and / or the parent monitor and / or the child monitor in the 1 ′ and the child device 2 ′.

  If the content of the emergency broadcast is incorrect, such as a malfunction of the fire alarm or the emergency button being pressed by the intercom master unit, the security company that undertakes management of the management controller 37 and security of the apartment will check it. After confirming the correctness / incorrectness, the text data of the phrase “Emergency broadcast with the contents of xxx at around midnight on month x day Y hour z” was sent to all the dwelling units and the entire building of the apartment house via the management controller 37. Is displayed on both the parent and child monitors 10 and 31 and the audio broadcasting is executed via the speaker, it is possible to prevent the residents of the apartment from being left uneasy for a long time.

  The collective entrance part 42 of the collective building includes a human sensor 43 that is a person detection means for collective entrance that detects a person in the collective entrance part 42 and a camera for collective entrance that is an image pickup means for collective entrance that images the person. 44, a collective entrance monitor 45 for displaying image data such as human face images obtained by the collective entrance camera 44, a microphone 46 as voice input means for the collective entrance, and a control unit 47 for controlling them. And the collective entrance part data obtained by these means is transferred to the recording part of the management controller 37 and stored for a certain period of time.

  With this configuration, from the moment when a person enters the collective entrance 42 of the collective building, the image is captured by the collective entrance camera 44 and the image is displayed on the collective entrance monitor 45. It is possible to improve crime prevention by recognizing that it is monitored. In addition, since the collective entrance portion data obtained by the collective entrance camera 44 and the microphone 46 is transferred to the management controller 37 and stored for a certain period of time, it can be easily used for verification of later crimes and the like.

  Although not shown in the figure, as a security system for a collective building, a collective interphone and a numeric keypad entry key input device arranged outside the common entrance, and an interphone master unit 1 or a communication terminal corresponding to each dwelling unit 36 of the apartment And a management controller 37 as a control device in which a collective intercom and an entry key input device are connected by wire or wirelessly, and an open / close door disposed at a common entrance in response to a command from the management controller 37 And an automatic opening and closing device that opens and closes.
