To visualize the extent of the sensor eld of view, the 90° eld of view is imprinted on the top

and bottom of the sensor case. If more of a visual indicator is needed, then a square framing

tool (e.g. raer square) or other tool with a right angle can be held above the sensor. By look-

ing down both edges of the tool, you can visualize the extent of the radar’s coverage.

Usually the front edge of the sensor’s eld of view is aligned to provide coverage beyond

the stop bar (see Figure 1.4). is allows you to place detection zones beyond the stop bar

to detect those vehicles that do not stop at or behind the stop line and will also allow the

sensor to see vehicles exiting queues. If the sensor pole is upstream from the stop bar, it is

recommended to pan in the direction of the stop bar.

Use the following steps to correctly align the SmartSensor Matrix:

1 Adjust the side-to-side angle so that the front edge of the eld of view provides a view
