Low-illumination network camera system

The utility model discloses a low-illumination network camera system. The camera system comprises a photosensitive device, a system control module and a power supply module. The camera lens is provided with a first optical filter for making infrared light not induced by the camera lens and a second optical filter for making infrared light induced by the camera lens. The first optical filter and the second optical filter are electrically connected with the system control module and used to perform the switching action after receiving a control command. The camera system does not adopt an infrared lamp, so the stability of the system is increased to make the service life of the camera longer, and at the same time, the camera system has advantages of low overall power consumption and less calorific value, and especially has significant power consumption advantage in the night vision condition relative to an infrared camera, so the camera system can be used in special environments, such as warehouses, coal mines,
