3.3.1 Test 1 - Detection Range

In Test 1, a person approaches the radar from outside the detection range of the radar at a variety of angles. Person walks at a typical walking speed, the person keeps arms loose by their sides. The distance at which the person is detected, is noted by the radar. User repeats the test three times for each angle.

The Detection Range pane in the Industrial Visualizer tool makes this measurement easy by labeling the detection distances of the different detection modes. For the overall detection distance, use the Mode 3 Detection Range (which is designed to turn on the video camera in a fully designed system).
