Abstract
The utility model discloses a camera with a controllable auxiliary light source for safety protection monitoring system, comprising an electricity source and an auxiliary light source system further. The auxiliary light source system includes a red light or white light LED group, a red light or white light LED driving circuit and a time-delay switch circuit connected in series. The time-delay switch circuit is connected between the electricity source and the LED driving circuit in series, and is provided with control signal input interface. The camera with the controllable auxiliary light source for safety protection monitoring system is connected to infrared invasion detector, the controllable auxiliary light source for safety protection monitoring system is opened of shut according to real-time control signal sent therefrom. Consequently auxiliary lighting for camera necessary for the safety protection system is provided, and auxiliary lighting is shut when no incident occurs and lighting is not needed, so that related cost are largely saved.
Description
Technical field
The present invention relates to a kind of video camera, relate in particular to a kind of video camera that is used for safety defense monitoring system.
Background technology
Because the illumination of common camera is difficult to accomplish zero illumination, the most use having illumination or bright place.But, the application of video camera at present more and more widely, a lot of places are in not illumination at night, video camera has just lost effect substantially like this.Therefore, there are many video cameras to adopt illuminating lamp or the illumination of LED infrared light control secondary light source now, such secondary light source general by day or the brightness of field of employment reach the reservation value, will close, illumination when the field of employment is lower than the reservation value, secondary light source can be opened automatically, in case open, just lights till the illumination of field of employment surpasses the reservation value always.But in the application of safety and protection system, some situation does not need secondary light source to open always, promptly opens secondary light source as required, so only has the video camera of light-operated secondary light source just can not satisfy this requirement.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of safety defense monitoring system video camera that can monitor in real time to the band secondary light source of light, when using video camera as required, the secondary light source system can open or close secondary light source according to control signal, promptly reaches the requirement of security protection, reaches purpose of energy saving again.
In order to solve the problems of the technologies described above the video camera that is used for safety defense monitoring system of the present utility model with controlled secondary light source, include power supply, described video camera also includes the secondary light source system, described secondary light source system comprises infrared or white light LEDs group, infrared or white light LEDs drive circuit and the delay switch circuit that order is electrically connected, delay switch circuit is series between power supply and the led drive circuit, and delay switch circuit is provided with the signal input end mouth.
Described signal input end mouth can be switching value signal input end mouth, also can be the digital controlled signal input port, can also be the combination of switching value signal input end mouth and digital controlled signal input port.
Based on above-mentioned design, video camera with controlled secondary light source of the present utility model is used for safety-protection system, its signal input end mouth can connect the passive infrared invasion detector of output switching value control signal in the safety-protection system, also can connect the bus system active infrared intrsion detector of exporting digital controlled signal, like this when the people enters or passes infrared safety monitoring zone, detector detects output switching value control signal behind the invador or digital controlled signal and gives delay switch circuit in the secondary light source system, secondary light source is opened, provide illumination to video camera, and after illegally the invador leaves guarded region, close automatically behind the secondary light source time-delay certain hour.The shooting floor light of safety-protection system necessity so both was provided, when the no situation of major part takes place, do not need to throw light on, can have closed floor light simultaneously, thereby saved relevant cost expenditure widely.
The signal input end mouth of delay switch circuit can also connect the control signal output circuit that is arranged in the safety-protection system in the supervising device in the above-mentioned secondary light source system, can control the secondary light source conducting and the time-delay closing of corresponding video camera by sending control signal artificially according to the situation of real-time monitoring.

Embodiment
The utility model is described in further detail below in conjunction with drawings and the specific embodiments.
Fig. 1 shows the video camera with controlled secondary light source that is used for safety defense monitoring system of the present utility model, include power supply 1 and secondary light source system 200, secondary light source system 200 comprises infrared or white light LEDs group 2, infrared or white light LEDs drive circuit 3 and the delay switch circuit 4 that order is electrically connected, delay switch circuit 4 is series between power supply 1 and the led drive circuit 3, and delay switch circuit 4 is provided with the signal input end mouth.The signal input end mouth comprises switching value signal input end mouth and digital controlled signal input port.
During use such as Fig. 2, shown in Figure 3, the digital controlled signal input port can connect the bus system active infrared intrsion detector 5 of one or more output digital controlled signals in the safety-protection system, and switching value signal input end mouth can connect the passive infrared invasion detector 6 of output switching value control signal in the safety-protection system.Like this when the people enters or passes infrared safety monitoring zone, detector detects output switching value control signal behind the invador or digital controlled signal and gives delay switch circuit in the secondary light source system, secondary light source is opened, provide illumination to video camera, and after illegally the invador leaves guarded region, close automatically behind the secondary light source time-delay certain hour.
The signal input end mouth of delay switch circuit can also connect the control signal output circuit that is arranged in the safety-protection system in the supervising device in the above-mentioned secondary light source system, can control the secondary light source conducting and the time-delay closing of corresponding video camera by sending control signal artificially according to the situation of real-time monitoring.
