## Best Practices

* Capture of rear license plates only
* Position the camera to have a mostly uniform lighting environment
* Avoid visual obstructions and retroreflective signage in the field of view
* Position the camera as close to a direct angle to the license plate as possible
* Use a license plate on a tripod or a parked vehicle in the intended capture area while calibrating
* Calibrate separate “day” and “night” mode camera settings using real-world day and night capture scenarios from the actual install location
* The entire vehicle should appear in the frame at the point of aim
* Target pixel density for optimal accuracy is > 120 PPF (Pixels Per Foot; 0.1” per pixel)
* The recommended minimum pixel density is 70 PPF
