Q:What is the difference between a camera and a monitor?

Camera digital camera The wide range of cameras, the basic principles of its work are the same: the optical image signal into electrical signals, in order to facilitate storage or transmission. When we shoot an object, the light reflected on the object is collected by the camera lens, focusing it on the light receiving surface of the camera (such as the target surface of the camera tube), and then through the imaging device to light into electricity, that is, "Video signal". Photoelectric signal is very weak, need to be pre-amplifier circuit to enlarge, and then through a variety of circuits for processing and adjustment, the final standard signal can be sent to the recorder and other recording media recorded, or spread through the transmission system or sent to the monitor display.

Q:What are the problems with the surveillance camera?

Monitoring the failure of the camera performance for several aspects: ① power supply is not correct equipment failure. ② equipment line connection reasons. ③ the quality of the equipment or components themselves. If it is installed problems caused by the problem, you can solve, but if it is to monitor the camera's own reasons, it would return to the factory maintenance. Now many manufacturers have done a good job after-sales service, such as Hai Kang, Dahua, Zhong Ying Xin and so on.

Q:Monitoring camera 6mm 8mm 12mm 16mm length and width can be according to how much.

According to the imaging principle, the smaller the focal length, the wider the field of view, but the distance is not clear. The larger the focal length, the narrower the field of view, but the longer the distance will be clearer.
