(two) the minimum illuminance is also known as sensitivity. It is CCD's sensitivity to ambient light, or the darkest light required for CCD normal imaging. The unit of illumination is lux (Lux), the smaller the value, expressed the need for less light, the camera is also more sensitive. The black and white camera sensitivity is about 0.02-0.5lux (Lux, color camera more than in 1lux. 0.1Lux cameras are used in ordinary surveillance situations; 0.02Lux cameras are recommended for use at night or when ambient light is weak.
