Automatic detector for starting security cameras
First Claim
1. An automatic detector for starting security cameras comprising a detection module mounted on the main body of security cameras while said detection module includes a regulator circuit, a light-sensitive circuit, a switch circuit, and a passive infrared sensor circuit, and a recorder control circuit;
- wherein the improvement is characterized by;
said regulator circuit used for providing power for internal circuit and connected to a power source;
said light-sensitive circuit connected to said regulator circuit and having a light-sensitive resistance therein by which to detect light in the environment in order to control said switch circuit;
said switch circuit used for controlling a light and connected to said light-sensitive circuit;
said passive infrared sensor circuit connected to said regulator circuit and said switch circuit and having a passive infrared sensor as well as a photoelectric switch circuit thereof;
said photoelectric switch circuit is disposed on said main body of security cameras and said passive infrared sensor is mounted near the front end of said main body of security cameras for detecting the infrared energy emitted from human bodies to switch on said main body of security cameras;
said passive infrared sensor circuit controls said switch circuit on or off to automatically switch said light connected therewith on or off. said recorder control circuit jointed with said passive infrared sensor circuit is connected to a video camera recorder;
while turning on said main body of security cameras for shooting, said passive infrared sensor circuit also sends out a signal simultaneously to activate said recorder control circuit to make said video camera recorder record.

Abstract
An automatic detector for starting security cameras comprises a detection module disposed on a video camera and the detection module includes a regulator circuit, a light-sensitive circuit, a switch circuit, and a passive infrared sensor circuit, and a recorder control circuit. The passive infrared sensor circuit is connected to the main body of security cameras, the switch circuit is connected to a light and the recorder control circuit is connected to a video camera recorder. In accordance with the structure mentioned above, the main body of the security cameras and the video camera recorder is started by the passive infrared sensor circuit to detect the infrared energy emitted from human bodies. If the illumination of the environment is insufficient, the light-sensitive circuit makes the switch circuit work to switch the light on so that the light is enough to make the pictures clearly.
