Point the camera where there is the least amount of obstructions (e.g., tree branches).
Install the camera where vandals cannot easily reach.
Secure cabling so that it is not exposed or easily cut.

NOTE: Accuracy of person and vehicle detection will be influenced by multiple
factors, such as the object’s distance from the camera, the size of the
object, and the height and angle of the camera. Night vision will also impact
the accuracy of detection.
Angle the camera so that objects of interest appear in the bottom
of the camera image.
Choose a location where objects of interest will be no further than 50ft (~15m) from the camera.
