Description

technical field

[0001] The invention belongs to the field of video monitoring, in particular to a camera protective cover wiper and a video monitoring system. Background technique

[0002] At present, the wiper is a frequently used device on the camera protective cover. Its function is to sweep away the rain, snow and dust on the glass of the camera. Therefore, it plays an important role for the camera. The electric wiper is composed of a motor, a crank, a transmission rod, a brush arm and a brush blade. When the motor rotates, it drives the crank and the transmission rod to work, so that the brush arm and the brush piece sweep away the rain, snow and dust on the glass of the camera. Adopt this wiper device, the area that the wiper device brushes out is fan-shaped, and places such as dirt, raindrop etc. are not brushed on the many dead corner areas on the window glass. The output shaft of the traditional wiper motor bears the force and rotational torque of the wiper in t...
