Color problem: All the black and white cameras are infrared sensors, infrared light in the visible light color camera in terms of the conditions for a stray light, color cameras will reduce the clarity and color reproduction, color camera filter is blocked To make participation infrared imaging infrared color camera sensors now have two practices, the first switching filter, blocking infrared entered under visible light conditions;. Remove the filter anti-theft monitoring projects without visible light conditions, so that the infrared enter such programs get good image quality, but the high cost and the switching mechanism causes a certain failure rate. The second control engineering, open a specific infrared channel security monitoring project on the filter, allowing light and infrared wavelengths the same infrared light come in, this approach does not increase the cost of remote monitoring projects, but slightly worse color reproduction. CCTV can provide some important areas close observation, monitoring and control. System complies with the relevant technical specifications. Generally in the system should be set up television cameras, in order to achieve all-round monitoring. Major equipment systems should be configured television monitors, video recorders and image processor time lag, so that the user can adjust the picture and look at any one of the remote control pan and zoom functions Renyiyitai have remote control of the camera.
