In the night mode, check if the input signals are correctly detected. You may simulate the
night mode by blocking the IR unit's light sensor. Change the triggering parameters when
necessary.
If your target area is a stretched out field of view, such as shooting a part of a highway,
finding the best focus can be a problem. You can use the Snapshot Focus utility to make
sure you acquire clear images of the license plates of passing vehicles.
