Abstract
The utility model discloses a camera that is used in the security system and is provided with a wireless controllable auxiliary light source. The camera comprises a power supply and an auxiliary light source system. The auxiliary light source system comprises an infrared or white-light LED group, an infrared or white-light LED drive circuit and a delay switch circuit, which are electrically connected in order; the delay switch circuit is connected in series between the power supply and the LED drive circuit, and is provided with a control signal input port; the control signal input port is provided with a digital signal encoding and decoding circuit, a wireless receiving circuit and a receiving antenna, which are sequentially connected. The camera is arranged in the security system and matches the infrared invasion detector that is provided with a wireless launching apparatus; the auxiliary light source system can be started and closed according to the real-time wire control signal. Thus the camera provides the auxiliary light that is necessary in the security system, and has no accidental occurrences almost under all the conditions; the auxiliary light can be closed when the lighting is not required; and thus the relevant costs are greatly reduced.
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 security system, some situation does not need secondary light source to open always, promptly opens secondary light source as required, and the video camera that so only has 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-protection system video camera to the band secondary light source of light can monitored in real time by wireless remote control, 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-protection system of the present utility model with wireless controlled secondary light source, include power supply, described video camera also includes the secondary light source system, described secondary light source system comprises the infrared or white light LEDs group that order is electrically connected, infrared or white light LEDs driving circuit and delay switch circuit, delay switch circuit is series between power supply and the led drive circuit, delay switch circuit is provided with the signal input end mouth, and this signal input end mouth is connected with the digital signal decoding decoding scheme successively, wireless receiving circuit and receiving antenna.
Based on above-mentioned design, when the video camera with wireless controlled secondary light source of the present utility model is used for safety-protection system, the signal triggering wireless launcher that is sent by infrared intrusion detector in the safety-protection system or control signal output circuit sends the wireless digital control signal of opening corresponding video camera, after being installed in radio receiver on the video camera and receiving control signal, through decoding, decoding output control level, open delay switch circuit, open the secondary light source of video camera, for video camera provides illumination, solved the problem that the common camera secondary light source can't be opened as required.So this video camera is installed in the place scope that needs to monitor, enter or pass the detection of passive infrared invasion detector or active infrared intrsion detector as the people, during guarded region, the output control signal was given wireless launcher after detector detected the invador, send the wireless digital steering order of opening corresponding video camera secondary light source by it, after the video camera wireless receiving module receives steering order, through decoding, decoding output control level is opened the secondary light source of video camera, provide illumination to video camera, after 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 automatically simultaneously, thereby saved relevant cost expenditure widely.

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 wireless controlled secondary light source that is used for safety-protection 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 driving 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 and is connected with digital signal decoding decoding scheme 5, wireless receiving circuit 6 and receiving antenna 7 successively.
During use as shown in Figure 2, this video camera can be placed in the safety-protection system of the band active infrared intrsion detector 8 that is provided with wireless launcher, when the people is interdicted the infrared beam that active infrared intrsion detector 8 transmitters send, survey receiver and just export the switching value signal, because the address setting with wireless launcher becomes and the identical address of video camera wireless receiver, relevant position in advance, therefore, after radio receiver receives the wireless command signals that corresponding emitter launches, with signal decoding, decoding and output control level give delay switch circuit 4 in the secondary light source system with the conducting of control circuit of light sources, it is luminous that led light source is lighted, for video camera provides illumination.And after illegally the invador left guarded region, on-off circuit 4 time-delay closings cut off circuit of light sources, finished the control to secondary light source.
Same, as shown in Figure 3 this video camera also can with the passive infrared invasion detector 9 corresponding settings of band wireless launcher in the safety-protection system, its principle of work is the same substantially, and just the device to wireless launcher output switching value signal is a passive infrared invasion detector 9.
In addition, this video camera can also be controlled in real time by the control signal output circuit that places the band wireless launcher in the supervising device, 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.
