This section provides the instructions to adjust the L5Q Camera after the camera is mounted.
4.1
Measuring the Camera Height
Procedure:
1
Use the Tape Measure to measure the height from the camera infrared sensor to the ground.
2
Use the Tape Measure to measure the distance from the ground below the infrared sensor to
the aiming distance in the road that corresponds to the measured height.

Aiming Distance
4 ft
55 ft
6 ft
56 ft
8 ft
57 ft
10 ft
58 ft
12 ft
59 ft
14 ft
60 ft
NOTICE:
Aiming at a point in the road that is farther than 60 ft away from the camera
decreases the license plate character recognition accuracy as the pixel size of the
resulting image decreases beyond acceptable levels. Aiming at a point that is less than
55 ft away decreases vehicle detection rates.
3
Aim the camera at the end of the Tape Measure out to the aiming distance.
NOTICE:
Aiming for distance calibrates when the camera captures images because of
the Motion Activation. Configuring the placement of License Plates in the image frame is
addressed in the Reconyx app in the Windowing tab.
