Video camera mounting and setup for the Traffic Detector module

General information

The video camera should be located at the top of the lamp pole at the edge of the road (side location), or at the horizontal truss above the road (central location).

If the camera meets the requirement described above (see the Video camera requirements for the Traffic Detector module section) and is aimed at the recommended directions, up to six lanes can be processed in case of a central camera location, and up to four lanes in case of a side location.

When mounting the Traffic Detector cameras, follow these recommendations:

1. Mount the cameras at a height of 8 to 20 m.

   Note.

   Optimum camera height is 12 m.

2. Mount the cameras not farther than 3 m from the road edge.
3. Horizon is not to be in the camera visibility scope.

Spatial orientation of the surveillance camera

The camera operates properly if its viewing zone contains not less than 25 m of road length, and the road in the image is as close to vertical as possible. The figure shows the road image if the camera is mounted at the recommended location.

The following figure shows the maximum allowable deviation of the road image from the vertical line (30 degrees).

 The camera mount should have two degrees of freedom, which allows it to ajust its orientation in the directions shown in the following figure.

 The camera can be tilted and rotated during its mounting and setup.
