When an RSA perimeter is armed, it is ready to detect targets that cross it. RSA perimeters are armed from their associated tracking devices in the Monitoring task.
By default, an armed RSA perimeter is black and a disarmed RSA perimeter is white.
When the perimeter sensor reports an error, the perimeter reports a system warning and
changes to orange. If an intruder is detected on the perimeter, the perimeter changes to
purple. All of these colors are configurable from Config
Tool on the tracking system's
Properties tab.
