Background

A monitoring camera is a device for monitoring and recording a specific area or place, and is widely used in security, traffic, business, industry, and personal fields. The use of monitoring cameras can improve security, prevent crimes, monitor traffic and activity, and are also used for real-time monitoring and recording of events. The indoor environment is relatively clean, and dust and dirt faced by the indoor camera are less compared with the outdoor environment. However, long-term operation and installation in a specific environment can also cause the camera lens surface to gradually accumulate dust and dirt. Although these minute particles are not obvious, they gradually affect the picture quality with the lapse of time, resulting in poor monitoring effect. At present, the dust removal of the indoor camera mainly still depends on manual periodic cleaning. This approach, while relatively simple, is still not as labor intensive for large-scale indoor monitoring systems. The increase of the dust removal frequency also brings about the increase of maintenance cost, and particularly, the dust removal problem is more remarkable for the high-density and large-scale monitoring layout.
