Camera protective cover
The protective cover is an important component in the monitoring system. It is a protective device to make the camera work normally under the conditions of dust, rain, high and low temperature, etc.
Protective covers are generally divided into two categories.
One type is a protective cover for indoor use. This protective cover has a simple structure and a low price. Its main function is to prevent the camera from dusting and has certain security protection functions, such as anti-theft and anti-vandalism.
The other type is the outdoor protective cover. This protective cover is generally an all-weather protective cover, that is, it can make the camera installed in the protective cover work normally regardless of the harsh conditions such as wind, rain, snow, high temperature and low temperature. Therefore, this protective cover has the functions of cooling, heating, rain and snow. At the same time, in order to enable the camera to take images normally in rain and snow, a controllable wiper is generally installed in front of the glass window of the all-weather protective cover. The current all-weather protective cover is a protective cover that uses semiconductor devices to heat and cool. This protective cover is equipped with semiconductor elements, which can be automatically heated or cooled, and the power consumption is small.
In addition, there are hemispherical and spherical protective covers. These protective covers have a universally adjustable bracket and have a beautiful shape.
The sealing performance of the outdoor protective cover must be good to ensure that rainwater cannot enter the inside of the protective cover to erode the camera. Some outdoor protective covers are also equipped with exhaust fans, heating plates, and wipers to better protect the equipment. When the weather is too hot, the exhaust fan works automatically; when it is too cold, the heating plate works automatically; when there is rain on the protective cover glass, the wiper can be activated through the control system. The choice of camera protective cover should first include the camera and lens used, and leave appropriate spare space, and secondly, choose the appropriate type of protective cover according to the use environment. The weight of the entire camera front including the gimbal is accumulated, and the bracket with the corresponding load-bearing value is selected. Also depends on the overall structure, the fewer the installation holes, the better the waterproof, and then whether the internal wiring is easy to connect, and finally the appearance, weight, mounting seat, etc. must be considered.
In the protective cover, in addition to the spherical protective cover used for the integrated camera system, there are different shapes such as cylindrical and rectangular, and the application occasions include two types of indoor and outdoor types. Indoor camera shields are mainly decorated, concealed and dustproof, while outdoor models are all-weather applications and must be able to adapt to different use environments. The material of the protective cover is mainly aluminum, alloy, extrusion molding, stainless steel, etc.
