Selecting a Mounting Location
You must select a mounting location before you can install the HD LPR Capture Kit. It is important to mount the kit
in an appropriate location to optimize the LPR accuracy.
The kit can be mounted in the overhead or roadside position. The LPR camera can recognize vehicles traveling
at up to 100 km/h (60 mph) when mounted in the recommended overhead mounting height, but the maximum
detectable speed decreases to 65 km/h (40 mph) when mounted in the maximum overhead mounting height or
when mounted in the roadside position.
Overhead Mounting
In overhead mounting, the HD LPR Capture Kit is mounted directly above the vehicle path. Refer to the following
tables for recommended and maximum mounting heights for each HD LPR Capture Kit model and their
corresponding horizontal distances to the license plate detection area.
