1. Pitch angle installation

Elevation installation is a special installation method, which is generally used at the entrances and exits of some sunken squares, basement entrances and exits, parking lot entrances and exits, etc. This method is a special method selected according to the needs of the site. In this way, the influence of various light sources must be considered. Avoid light interference. The protection of surveillance engineering cameras shall also be considered in detail. The surveillance camera should be a product camera with mature light processing.

2. Flat angle installation

The installation height of the surveillance engineering camera is close to the height of the face of ordinary people, which fully shows the details of facial features. It is the angle for the installation of the surveillance camera at the entrance and exit of the building. During indoor installation, the installation distance, position and height can be adjusted to achieve a flat angle. With the emergence of three-axis and two axis adjustable hemispherical surveillance cameras, most surveillance cameras can be installed close to the wall at a flat angle. The disadvantage is that the concealment is not strong, it is easy to destroy the on-site environmental landscape, and it is easy to be affected by the light environment.

3. Pitch angle installation
In this way, surveillance cameras are often ceiling mounted or hoisted. The utility model has the advantages of convenient installation and concealment, and can avoid the influence of direct reflection of part of the light. In this way, it should be noted that the included angle between the surveillance camera and the face should not be too large, otherwise the overhead picture is large and the facial features are less. The disadvantage is to reduce the recognition rate. When the on-site environment is limited, in order to obtain the effect, the installation distance can be appropriately selected to adjust the object distance and realize the ideal camera of angle.
