When the camera when ingested brighter scenes, the picture displayed on the monitor usually bright, in addition to the light sensitivity of the camera are also important factors affect the resolution.

Camera sensitivity CCD (CMOS) to ambient light sensitivity, or a normal CCD imaging of the dimmest light required. The unit is lux illumination (Lux), the smaller the value, expressed the need for the less light, the more sensitive the camera. Moonlight level (about 0.1Lux) and Starlight pole (0.01Lux or less) high-sensitivity cameras can work in very dark conditions, 2 ~ 3Lux a general illumination.

When we buy the camera first take into account our environment, and then select the sensitivity depending on the environment of different products.
