Camera Aiming
Accurate aiming and positioning of the camera is essential to maximizing plate capture performance.
Proper aiming ensures that license plates traveling through the camera's field of view are at an ideal
distance and angle for generating images that are as clear and readable as possible.
Remember these helpful tips when aiming the camera:
• Point the camera in the same direction as the flow of traffic so that the back of vehicles are being
captured as they pass.
• Aim the camera so that license plates are horizontally parallel with the blue zone as they pass
through. Minimize the rotation of the camera with respect to the plate.
• While aiming, adjust the example plate at the center of the image towards the green boxes that
appear after each detection. Avoid the orange and red boxes.
• If the camera is at the correct distance, license plates will fit within the example plate as they pass
through the blue zone.
• In locations where traffic is intermittent, it is helpful have an assistant available to drive a vehicle
through the estimated capture zone while the camera is being aimed.
3.6.1
Preparing to Aim the Camera
Before the camera can be aimed, the Mobile Companion Application needs some information about
the position of the camera. This information is used by the application to calculate the angle and
distance from the camera to the license plate capture zone, and then adjust the camera accordingly.
Procedure:
1 Tap Begin Aiming in the Mobile Companion Application.
2 Tap Join to allow the application to connect to the camera over Wi-Fi and display the video
stream.
If prompted, tap OK to allow the application to locate devices on the local Wi-Fi network.
3 Select the side of the road that the camera will be mounted on confluent with the direction of
traffic.
4 Measuring in feet, determine the two distances A and B that form the legs of a triangle between
the camera and the license plate capture zone:
• A is the distance that the camera is laterally offset from the capture zone.
• B is the distance from the camera to the perpendicular line across the road formed by
distance A.
NOTE: If the installation site prohibits the use of a tape measure, use a distance
measuring app like Apple Measure or Google Measure.
