INSTALLATION INSTRUCTIONS*
An LPR camera is designed to read a license plate only. When a license plate passes by the
camera, the reflective film on the plate will be reflected 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 130 pixels wide. This translates roughly into an image
no wider than 5-6 feet assuming 4CIF standard definition 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 off 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 CAPTURED IMAGE SHOULD BE FILLED WITH THE FULL WIDTH OF THE VEHICLES
