[0002] Monitoring equipment is one of the most commonly used devices for security protection work. It is used in monitoring systems in important areas, such as stations, banks, exhibition halls, etc., and is often needed outdoors to monitor crowded areas to avoid potential safety hazards and maintain public safety.

[0003] At present, in outdoor security monitoring equipment, especially when these monitoring equipment are arranged at outdoor intersections with heavy traffic, the exhaust gas discharged by vehicles and the dust raised by cars adhere to the camera lens. As the dust accumulates, the clarity of the monitoring equipment will decrease. Therefore, the existing technology mostly installs a camera cleaning roller on the monitoring equipment to wipe the camera lens. After the cleaning roller has been used for a period of time, a large amount of dust will adhere to its surface. Then driving the dusty cleaning roller to wipe the camera will easily scratch the camera lens, and the cleaning effect of the camera is also very limited. Utility Model Content
