Infrared dual-inspection image pickup device of digital video monitoring site

Provided is an infrared dual-inspection image pickup device of a digital video monitoring site. The front end of a digital camera (1) is connected with an infrared dual-inspection detector (2). The digital camera (1) is further connected with a client (5) through a switch (4). The digital camera (1) and the infrared dual-inspection detector (2) are connected with a DC power supply (3) which supplies power. Technology and equipment support for image monitoring for unattended to-be-monitored points under a low bandwidth are provided. The device uses total range precise temperature compensation, and no matter how ambient temperature changes, detection sensitivity is kept constant all the time, and no temperature dead zone exists. Microwave detection is stable and reliable, and anti-interference capability is good, the maximum coverage area is wider and farer. The device can set visual area forming, inspection image pickup operation is accurate and flexible, and energy saving and efficient.
