Abstract

PURPOSE:To monitor at night without using an auxiliary illumination by operating a camera for night vision by signals that detected the movement of a person or an object, thereby detecting and monitoring a visitor. CONSTITUTION:The monitoring device is installed on the ceiling of a monitoring area near a doorway 3 and detects and photographs a person going in and out from the doorway 3. The signal processing circuit 17 and video signal processing circuit 18 of the monitoring device 16 are connected to an annunciator 20 and a monitor TV 21 of a general monitoring board 19, and announcing and monitoring by detection of a visitor can be made simultaneously by the general monitoring board 19. That is, when a detection signal of the signal processing circuit 17 is inputted, a driving circuit 22 of an infrared light emission diode 14, a TV camera 2 and video signal processing circuit 18 are operated to make announcing of a visitor and monitoring simultaneously.

Description

[Detailed description of the invention]

[Technical Field] The present invention relates to a monitoring device for notifying visitors. Background technology] Conventionally, devices for monitoring US customers include a photoelectric or ultrasonic type visitor alarm 1 that detects US customers and notifies them with a chime, etc., and a monitor device using a TV camera 2. If you want to perform detection and monitoring at the same time, as shown in FIG.
J-”/ →← １ し T υ Todoroki no et al. 9 ９ Qll h l い It was necessary to set up 5. Also, when switching from visitor detection to monitor at night, to compensate for the lack of brightness for photography. Auxiliary lighting 4 was required.There was also the problem that the TV camera 2 stood out and gave a sense of discomfort to visitors. [Objective of the Invention] The present invention was made in view of the above-mentioned problems, and the purpose and purpose of the present invention were achieved. What we do is that we can detect visitors and monitor them with one device, we can monitor them even at night without using auxiliary lighting, and we can monitor the presence of a TV camera so that it is not visible from the outside and does not make visitors feel uncomfortable. [Disclosure 1 of the Invention] The present invention provides a night vision T, which comprises a sensor for detecting the movement of people or objects, an infrared light emitting means, and a solid-state image sensor that senses the infrared light.
The device is characterized in that the V-camera is housed in an integrated device body and placed in the monitoring area. The present invention will be explained below with reference to Examples. The upper embodiment WIJi figure shows a partially omitted perspective view of the embodiment. Inside the device main body 7, which is composed of a lower cover 5 and an upper cover 6, there are a light receiving element 8 that constitutes a rechargeable visitor sensor 1,
Circuit board 1 on which light emitting element 9 and signal processing circuit 17 are mounted
0. A circuit board 11 on which a TV camera 2 consisting of a COD element and an infrared light emitting diode 14 are mounted, and a circuit board 15 on which a video signal processing circuit 18 is mounted are built in, and the lower cover 5 is mounted on the ceiling. Attached is support 1 on stand 12.
3, it is rotatably supported in the vertical and horizontal directions. The monitoring device 16 configured as described above is attached to the ceiling of the monitoring area near the doorway 3, as shown in FIG. 2, and detects and photographs people entering and exiting through the doorway 3. Here, the signal of the signal processing circuit 17 of the monitoring device 16 and the video signal processing circuit 18 are connected to the alarm 20 and the monitor TV 21 of the general monitoring board 19, and the notification and the monitor based on the detection of the visitor are simultaneously transmitted by the general monitoring board 19. It is now possible to do this. Figures tj & 3 show the circuit configuration of this embodiment, and when a detection signal of the signal processing circuit 17 is input, it operates the drive circuit 22 of the infrared light emitting diode 14 and also operates the TV camera 2.
And the video processing circuit 18 is operated, so that visitor notification and monitoring can be performed at the same time. Further, monitoring can be performed at any time by switching the signal processing system on the comprehensive monitoring panel 19 using the selection switching circuit 23, regardless of the detection by the visitor sensor 1. The photoelectric visitor sensor 1 is a well-known one, and its type is not particularly limited. In addition to the rechargeable type, other sensors such as ultrasonic waves may also be used.

【Effect of the invention】

The present invention is a night vision T-shirt consisting of a sensor that detects the movement of people or objects, an infrared light emitting unit, and a solid-state image sensor that senses the infrared light.
Since the V-camera is housed in the integrated device body and placed in the monitoring area, there is no need to install the TV force/velocity sensor separately as in the past, and the TV camera is housed inside the device body. Since the TV camera is not conspicuous, it does not make visitors feel uncomfortable, and since auxiliary lighting is not required at night, it is possible to monitor American customers, so visitors will not know that you are being monitored. This effect is achieved.
