Key words: security monitoring camera installation angle
Guide: the installation position of surveillance camera can be divided into flat angle, depression angle and elevation angle according to different angles. In practice, the best way is flat angle installation, which can show more facial details. It is recommended that the maximum viewing angle should not exceed 15 degrees. When the field environment is limited, in order to obtain the best effect, the installation distance can be appropriately selected to adjust the object distance to realize the idealization of the angle.
The installation position of surveillance camera can be divided into flat angle, depression angle and elevation angle according to different angles.
flat angle installation: the installation height of the surveillance camera is close to the height of ordinary people's face, which fully shows the details of facial features. It is the preferred angle for the installation of the surveillance camera at the entrance and exit of the building. During the indoor installation, the installation distance, position and height can be adjusted to achieve the flat angle. With the emergence of three-axis and two axis adjustable hemisphere surveillance cameras, most surveillance cameras can be installed close to the flat angle by sticking to the wall. Its disadvantage is that the concealment is not strong, it is easy to damage the scene environment landscape, and it is easy to be affected by the light environment.
prone angle installation: in this installation mode, the monitoring camera often adopts ceiling or lifting mode. Its advantages are convenient installation, concealment, can avoid the impact of direct reflection of some light. In this way, we should pay attention to the angle between the surveillance camera and the face should not be too large, otherwise the top of the head picture is larger and the facial features are less. The disadvantage is to reduce the recognition rate.
. This way is a special way selected for the needs of the site. In this way, the influence of various light sources must be considered. Avoid light interference. The protection of surveillance cameras should also be considered in detail. The monitoring camera should be the product with mature light treatment.
