For building automation of a perimeter, fence or wall, we distinguish two application areas, area monitoring and location indicator systems.
With area monitoring, software in the sensor will manage all monitoring areas. The system signals if intruders are present by releasing the switching output and triggering an alarm whenever an area is violated. This may, for instance, also be triggered by objects or items regardless of whether they are mobile or not.
The sensor uses the measuring data with which it has been provided to determine the location.
When this is done, the devices are set so that small animals, adverse weather conditions or mere passers-by do not trigger any false alarms.
