WARNING: Please read the disclaimer to make sure that all of the installation constraints have been fulfilled!
Moreover, the camera should frame the back of vehicles, so to avoid problems due to car headlights; it is also advisable to use an outdoor varifocal camera. Cameras should be installed on a pole or any other steady element, otherwise camera's vibrations could negatively affect the performance. Minimum height required is 5 meters (it is crucial to avoid occlusions between vehicles and that the whole vehicle is framed in the image and not just a part of it.), with a tilt angle of 15°. Lastly, please remember that to properly detect vehicles the minimum pixel area required is 50x50; any eventual zoom has to be configurated according to this requirement.
