Embodiment Construction

[0036] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0037] Existing protective devices based on wipers, fans, etc., can only clean the surface of the monitoring window invaded by rain, fog, and wind and sand, and do not fundamentally isolate the monitoring window from harsh environments such as rain, fog, and wind and sand. Therefore, the existing protection The device does not really solve the pro...

Abstract

The invention embodiment discloses a video monitoring camera head protection method and device; the method comprises the following steps: a protection controller obtains present environment visibility according to real time monitoring environment information; if the present environment visibility is smaller than a preset first control threshold value, and the present window state of a transparent window protection layer is open, then the present window state of the transparent window protection layer is switched to a closed state; in a protection method of the prior art, a monitoring window of a camera head is eroded by severe whether like rain, fog and dusts, so the monitoring window is worn and aged, and is low in transmittance; the method and device of the invention can solve the said problems.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular, to a camera protection method and device for video surveillance. Background technique [0002] Usually, protective covers for optical instruments with special purposes, such as outdoor protective covers for cameras, etc., are exposed to harsh outdoor environments for a long time, especially in rainy areas and desert areas. The erosion of bad weather causes the surface of the monitoring window to wear and age, resulting in a decrease in transmittance, which changes the optical parameters of the optical instrument, thereby reducing the imaging quality of the optical instrument. Further, due to the special manufacturing process and complex structure of the optical instrument protective cover, the maintenance cost is high, and the replacement of the monitoring window of the protective cover is more complicated. [0003] In order to prevent the monito...
