Instructions
An LPR camera is designed to read a license plate only. When a license plate passes by the
camera, the re ective lm on the plate will be re ected back to the camera which gives you
the good clear shot of the plate. You will ONLY capture an image of the plate.
US license plates need to be at least 216 pixels wide. This translates roughly into an image
no wider than 5-6 feet assuming 1080P standard de nition video.
1
The horizontal angle between the camera and plate should be within 20° degrees. This
means that if your camera is 10 feet away from the plate, the plate cannot be more than 3
feet to the right or left of the camera.
2 The vertical angle between the camera and plate is within 30° degrees. This means that if
your camera is 10 feet away from the plate and the plate is 3 feet o the ground, the camera
cannot be mounted more than 8 feet high.
3 Attempting to position the security camera at odd angles or exceeding the distance
capabilities will result in a poor shot of the plate
4 The DVR's recording fps should be at the highest to assure best capture quality.
THE CAMERA SHOULD BE MOUNTED AT AN ANGLE NO GREATER THAN 30 DEGREES
