When purchasing a camera shell, the first thing to consider is the waterproof property of the camera shell and the quality of the shell. If the material is poor, the shell will be out soon. Because there are too many places to be monitored for outdoor monitoring, it is necessary to select a larger size and adjustable focus when purchasing the camera shell so that enough scenes can be monitored. Generally, there are HS-85T/100/110 enclosures.
