监控摄像机设置参数（Monitor camera setting parameters） Basic settings for monitoring camera parameters [Author: light surveillance camera 2011-09-15 Click: 120] Light | camera surveillance camera | infrared camera | night vision camera | waterproof camera resolution basic settings (1) AGC ON/OFF (automatic gain control) The camera has a signal from the CCD amplifier can be used to standard video amplifier, the amplification gain is equivalent to a higher degree of sensitivity, but in the light of the environment will make the video amplifier overload, signal distortion. When the switch is at ON, the lens aperture is fully switched on under low brightness conditions, and the gain is automatically increased to obtain a clear image. When the switch is at OFF, the image with natural and low noise can be obtained at low brightness. (2) AWB ON/OFF (automatic white balance) When the switch is switched to ON, the characteristics of the light source / color temperature are detected by the lens to automatically set the white level continuously, even if the characteristic / color temperature change can control the gain of the red and blue signals. (3) ALC/ELC (automatic brightness control / electronic brightness control) When the ELC is selected, the electronic shutter continuously automatically changes the exposure time of the CCD image sensor according to the brightness of the incoming light (generally adjusted continuously from 1/50 to 1/10000 seconds). In this mode, you can replace the ALC automatic iris lens with a fixed or manual diaphragm lens. It should be noted that in outdoor or bright environments, due to limited ELC control range, ALC lenses should be selected. Under certain unique lighting conditions, the following conditions may occur: (1) strong streaking or blurring in high brightness objects such as spotlights or windows. (2) the image is remarkably flickering and the color reproduction is unstable. (3) there is a periodic change in the white balance. If these phenomena
