Park cameras are generally installed in the park management office. First, determine the monitoring area, expected destination, target object and investment budget; Select the camera type according to the size of the monitoring area and the detailed requirements of the monitoring screen; Camera signal transmission medium and power supply mode; Choose whether the lens size is wide-angle or telephoto; According to the site environment, try to reduce the difficulty of wiring, avoid trees, strong electricity, overheated pipes and strong light. The installation position of the monitoring camera can be divided into: flat angle, lower angle and upper angle due to different angles. The best installation method in practice is straight angle installation, which can show more facial details. Dongguan Ruishi-Vision suggests that the maximum overlooking angle should not exceed 15 degrees. When the site environment is limited, in order to obtain the best effect, the installation distance can be appropriately selected to adjust the object distance and realize the idealization of the angle.
