In the present embodiment, the TV camera can capture a range wider than the detection range of the detection unit 11. The TV camera is temporarily stored in a memory for a predetermined short time at the time of shooting (regardless of save standby or save), and the shot images are automatically overwritten sequentially. On the other hand, the recording device is a known device that can store (record) a captured image of a TV camera and store the image until an erasing or overwriting operation is performed, and can reproduce the stored image. The photographing means 13 is connected to the control means 21, and the control means 21 instructs the storage of the photographed image. The photographing means 13 is connected to a display means 19 comprising an image display device (liquid crystal device or CRT).

  The notification prohibition means 15 is composed of a notification prohibition signal receiving device, receives a notification prohibition signal transmitted (transmitted) from the notification prohibition signal transmission device 30, and communicates with the control means 21 connected to the notification prohibition means 15. Send. The notification prohibition signal includes a unique recognition signal (ID code) for each notification prohibition signal transmission device 30. On the other hand, the notification prohibition means 15 includes a notification prohibition signal transmission device to which notification prohibition is permitted. It is preferable that 30 recognition signals (ID codes) are set in advance so that even if a notification prohibiting signal different from the set recognition signal (ID code) is received, it is not transmitted to the control means 21. Further, the determination of the recognition signal (ID code) may be performed by the control unit 21 without being performed by the notification prohibiting unit 15.

  The notification means 17 is composed of a sound generating device such as a speaker or a buzzer or a notification capable device such as a light emitting device, and is connected to the control means 21 so that when the control means 21 receives a human detection signal from the detection means 11, the sound is notified. Generation and light emission. In this embodiment, it is constituted by a sound device, and the tone color and the sound volume are made different between the detection by the first sensor of the detection means 11 and the detection by the second sensor.

  The display means 19 comprises an image display device such as a liquid crystal display device or a CRT, and is connected to the photographing means 13 so as to be able to display a photographed image (stored standby state) of the photographing means 13 and a reproduced image after storage. Yes.

  The control means 21 comprises a CPU and controls the photographing means 13 and the notification means 17. In the present embodiment, when a detection signal of the person by the first sensor is transmitted from the detection means 11 and received by the control means 21, the photographing means 13 is activated to start photographing (set to a storage standby state), The notification means 17 performs a first notification. At this time, the photographed image of the photographing means 13 (image in the storage standby state) is displayed on the display means 19. The first notification by the notification means 17 may be either one or both of intimidating an illegal intruder or informing a householder of an illegal intrusion. Further, in this embodiment, when a human detection signal from the second sensor is transmitted from the detection means 11 and received by the control means 21, the photographing means 13 starts storing the photographed image and the notifying means 19 The second notification is performed. The second notification is performed with a tone color different from the previous one or with a large volume. In the case of notification by light emission, the first notification by detection of only the first sensor and the second notification by detection of both the first and second sensors can be performed by changing the light emission mode, for example, changing the blinking interval, You may distinguish by providing a several light-emitting device and changing luminescent color. Further, when the notification prohibiting means 15 receives the notification prohibiting signal from the notification prohibiting signal transmission device 30, the notification means 17 prohibits the notification, and in the present embodiment, the photographing means 13 prohibits the storage of the photographed image. As described above, when the notification prohibition signal includes the recognition signal (ID code) unique to the notification prohibition signal transmission device 30 and the determination of the recognition signal (ID code) is not performed by the notification prohibition means 15. When the control means 21 determines the recognition signal (ID code) and matches the preset recognition signal (ID code), the notification by the notification means 17 or the photographing by the photographing means 13 Prohibit saving of shot images.

It is also possible to adopt a configuration that prohibits saving of captured images.

  An operation example of the crime prevention monitoring system 1 according to the embodiment will be described. First, when a person enters the detection range of the first sensor in the detection unit 11, the first sensor of the detection unit 11 detects and starts shooting (stored standby state) by the shooting unit 13, and the display unit 19 is displayed. At that time, the photographed image is temporarily stored for a predetermined short time and is sequentially overwritten and saved. Further, when the photographing unit 13 starts photographing, the notifying unit 17 performs first notification.

  Further, when the intruder approaches and enters the detection range of the second sensor in the detection means 11, the second sensor detects and starts to save the photographed image from the photographing part once memorized by the photographing means 13 immediately before. In addition, the notification means 17 performs the second notification with a tone color or volume (light emission with different flashing interval or emission color in the case of a light emitting device) or the like different from the first notification so far. At this time, if the intruder has the notification prohibition signal transmission device 30, the notification prohibition means 15 detects the notification prohibition signal transmitted from the notification prohibition signal transmission device 30, and the notification means 17 2 Prohibits notification and prohibits storage of the photographed image by the photographing means 13. By prohibiting the second notification, for example, it is possible to know that a family member has returned home.
