Description

Surveillance system with automatic recording function of relevant channel when situation occurs

The present invention relates to a surveillance system having an automatic recording function when a situation occurs. More specifically, the video tape recorder and the video tape can be automatically recorded only when a situation or an event that needs to be monitored has occurred. The present invention relates to a surveillance system having an automatic recording function in the event of a situation that can extend the life and make a surveillance system at a low cost by allowing the use of an existing video tape recorder.

Background Art In the related art, a closed circuit surveillance system in which a video tape recorder (VTR) is coupled to a video camera such as a CCD (Charge Coupled Device) camera for unattended monitoring of a specific area of space for a specific time is widely used. The administrator of the above closed circuit monitoring system can grasp in detail the situation that has occurred in a specific space for a specific time by reproducing the recorded video tape using a video tape recorder.

However, in the conventional closed circuit monitoring system, the image of a specific space is connected by coaxial cable connection between the video camera and the closed circuit monitor so that the electric image information signal output from the video camera is input to the input terminal of the closed circuit monitor. The information signal is displayed on the screen of the closed circuit monitor.

However, the conventional closed-loop monitoring system described above uses a video tape recorder continuously recording video images input through the camera even when a situation or an event to be monitored specifically does not occur. Is frequently made over a long time, thereby shortening the lifespan of the video tape recorder and the video tape.

If, due to economic circumstances or negligence in management, the video tape recorder and video tape that have reached the end of their service life cannot be replaced by the presenter, the recording and playback image quality of the video tape will be significantly degraded, thus fully functioning as a surveillance system. There is also a problem.

The object of the present invention is to solve the above-mentioned problems, and to extend the lifespan of the video tape recorder and video tape by allowing the video tape to be automatically recorded only when a situation or an event that must be specifically monitored occurs. At the same time, by providing an existing video tape recorder in the system configuration, it is possible to provide a surveillance system having an automatic recording function when a situation occurs.

2 is a detailed circuit diagram of a remote control unit of a monitoring system having an automatic recording function when a situation occurs according to an exemplary embodiment of the present invention. As shown in FIG. 2, the configuration of the remote control unit 60 of the monitoring system having an automatic recording function when a situation occurs according to an embodiment of the present invention includes a key matrix for allowing a user to input a command, and a key matrix input from the key matrix. In a general remote controller comprising a controller IC1 for generating and outputting a kisscan code according to a signal and light emitting diodes D1 and D2 for converting and outputting an electrical signal output from the controller IC1 to an optical signal. The control circuit SI further includes additional circuits R3 to R9, C4 to C7, and IC2 for forcibly supplying the recording signal to the controller IC1 when the control signal SI is input.

According to the above configuration, the operation of the monitoring system having an automatic recording function when a situation occurs in accordance with an embodiment of the present invention is as follows.

When the operation is started by supplying power, the control unit 40 scans whether a movement of a person is detected from the plurality of PIR sensor units 10, and when a signal is input from any one of the PIR sensor units 10, the channel is detected. The camera unit 20 and the microphone unit 30 are continuously selected to allow a signal to be input. As such, the video signal input from the camera unit 20 and the audio signal and audio signal input from the microphone unit 30 are output to the VTR 70 via the control unit 40. On the other hand, the control unit 40 outputs the control signal SI to the remote control unit 60 to forcibly generate a recording signal from the remote control unit 60 to control the VTR 70 to perform recording in the VTR 70. To lose.

A process of forcibly generating a recording signal by the remote controller 60 will be described with reference to FIG. 2 as follows. When the remote control unit 60 is used for general purposes, when the user presses the recording key REC of the key matrix, a signal is input to the common terminal (pin 19) and the recording terminal (pin 12) of the controller IC1. Accordingly, the controller IC1 outputs a signal to the output terminals 13 and 14 so that the light emitting diodes D1 and D2 are operated so that the recording signal is transmitted to the VTR 70 as an optical signal. When the control signal SI is input from the control unit 40 when the remote control unit 60 is used for the monitoring system, the control signal SI is transmitted to the 5 of the integrated circuit IC2 via the resistor R5. The signal input to the third pin of the integrated circuit IC2 is output to the fourth pin through the resistor R8 by turning on the transgate to turn on the transgate to charge the capacitor C5. In this process, a pulse signal is instantaneously generated and input to pin 13 of the integrated circuit IC2 to turn on the transgate so that pins 1 and 2 are short-circuited to produce the same effect as pressing the recording key (REC) of the key matrix. To pay. Meanwhile, the signal charged to the capacitor C5 is charged to the capacitor C7 via the diode D3 and input to the pin 6 of the integrated circuit IC2 during the time constant time R9 × C7 to turn on the transgate. The voltage charged in the capacitor C6 is discharged to the ground during the time constant time. If pins 9 and 8 of the integrated circuit IC2 are turned off after the time constant time, pin 12 is energized and pins 10 and 11 are shorted by turning on the transgate. Has the same effect as pressing. Therefore, the recording is automatically stopped at a certain time after the start of recording, which can be changed by adjusting the time constant.

As described above, the recording is performed, and the control unit 40 may output a warning sound or a warning message to the intruder by using the warning unit 50.

As described above, in the embodiment of the present invention, the video tape recorder and the video tape can be automatically recorded only when a situation or an event to be specifically monitored occurs, while extending the life of the video tape recorder and the video tape. By enabling the use of video tape recorders, it is possible to provide a surveillance system with an automatic recording function in the event of a situation in which the surveillance system can be configured at a low price. This effect of the present invention can be modified and used by those skilled in the art without departing from the spirit of the present invention in the field of closed circuit monitoring systems.
