The wireless surveillance camera sometimes suddenly sounds like a shutter. Why?

There is noise in the lens: it should be an infrared camera, and there should be something wrong with turning on the infrared photosensitive resistor. If it is at night, there may be abnormal noise, and if the light is stable, it will also ring, indicating that there is something wrong with the camera.

The main reason why the monitor keeps ringing is that the hard disk is lost. Users can check the computer hard disk and plug in the data cable or power cable again to solve the problem. If it still can't be solved, it is recommended to find a professional to repair it.

Preventive measures:

The rated voltage of the wire for monitoring camera should be greater than the working voltage of the line; The insulation of the conductor should be suitable for the installation mode of the line and the environmental conditions of laying. The cross-sectional area of cable conductor should meet the requirements of power supply and mechanical strength.

Surveillance cameras should be installed horizontally or vertically in buildings. Casing protection should be added when wiring (plastic pipe or iron pipe should be selected according to the technical requirements of DU pipe in the room), and metal hose can be used for ceiling wiring, but it needs to be fixed firmly and beautifully.
