Description

Technical Field

[0001] The utility model relates to the technical field of camera dust removal, in particular to a camera lens dust removal device. Background Art

[0002] The camera converts the optical image signal into an electrical signal for storage or transmission. When we shoot an object, the light reflected from the object is collected by the camera lens and focused on the light-receiving surface of the camera device (such as the target surface of the camera tube). The camera device then converts the light into electrical energy, which is the "video signal". The photoelectric signal is very weak and needs to be amplified by the pre-amplifier circuit, and then processed and adjusted by various circuits. The final standard signal can be sent to a recording medium such as a video recorder for recording, or transmitted through a transmission system or sent to a monitor for display.

[0003] Surveillance cameras are one of the most common cameras in people's lives. They are video equipment used to monitor and record specific areas or places. These cameras are usually used for security monitoring, surveillance, recording and tracking activities to ensure safety and provide evidence. Such cameras are generally installed at high places to increase the width of the picture and improve the scope of monitoring. However, in recent years, environmental deterioration and frequent extreme weather events are becoming more and more common around the world. Extreme weather such as sandstorms occur frequently. A large amount of sand, dust and particulate matter brought by sandstorms will be carried into the air by the wind and deposited on the surface of the surveillance camera, including the camera lens. These particles will adhere to the surface of the lens, causing the lens to become blurred and unclear, affecting the shooting effect of the surveillance camera. The surveillance camera is installed at a high position, and it is more difficult to clean the dust. Utility Model Content
