How to choose the right position
The camera should be centered above the entrance door. It
is also recommended that the camera should be positioned
as close as possible to the doorway without any obstacles.
How to define the focal length
A standard-sized entrance door with a width of 2-3m requires
one camera.
The coverage varies based on the camera's focal length, as the
table shows.
