Security equipment detection,
Protective covers are also one of the most commonly used equipment in monitoring systems, mainly divided into indoor and outdoor types. The main differences between indoor protective covers are their size, appearance, and qualified surface treatment. The main function is to prevent dust and damage. The outdoor protective cover has good sealing performance, ensuring that rainwater cannot enter the inside of the protective cover and corrode the camera. Some outdoor protective covers also come with exhaust fans, heating plates, and wipers to protect equipment. When the weather is too hot, the exhaust fan automatically operates; The heating plate automatically operates when it is too cold; When there is rainwater on the protective cover glass, the wiper can be activated through the control system. When selecting a protective cover, first consider the overall structure. The fewer installation holes, the more waterproof it is. Then, check whether the internal wiring is easy to connect. Finally, consider appearance, weight, installation seat, and so on
