The invention relates to the technical field of monitoring lenses, in particular to a monitoring lens capable of eliminating the influence of reflection, and solves the problems that the monitoring lens in the prior art is influenced by multiple factors such as illumination conditions and environmental factors, so that collected or collected images and videos are not clear and even cannot be imaged when being serious. The monitoring lens capable of eliminating the reflection influence comprises a lens body, a rotary sleeve is arranged at a port of the lens body, a threaded sleeve is fixedly installed at the end, close to the lens body, of the rotary sleeve, the rotary sleeve is in threaded connection with the lens body through the threaded sleeve, a polarization filter is arranged in the lens body, and the polarization filter is in threaded connection with the lens body. A stabilizing structure used for fixing the polarization filter is arranged in the lens body. By arranging the polarization filter, the illumination intensity and the reflection influence of the shot target can be effectively reduced, meanwhile, the purpose of improving the contrast ratio and the definition of a shot picture is achieved, and the adverse influence of reflection on shooting is effectively avoided.
Description
technical field [0001] The invention relates to the technical field of monitoring lenses, in particular to a monitoring lens that eliminates the influence of reflections. Background technique [0002] Surveillance lens is the best tool for collecting images and has a wide range of application scenarios, such as car monitoring, road surface monitoring, home monitoring and other scenarios. It is the main front-end component of image collection. [0003] Surveillance lenses are affected by lighting conditions, environmental factors and many other factors. The images and video data collected and collected by natural surveillance lenses are also affected by lighting conditions and environmental factors, which may cause the images collected or collected. , the video is unclear, unclear, or even in severe cases, it cannot be imaged. SUMMARY OF THE INVENTION [0004] The purpose of the present invention is to provide a monitoring lens that eliminates the influence of reflection, ...
