1. A computer implemented method of determining identity of persons detected in a monitored site having a plurality of motion sensors each monitoring one of a plurality of monitored spaces of the monitored site, and a plurality of distributed RF receivers, each having a different reception coverage area overlapping with a respective one or more of said plurality of monitored spaces, said method comprising:

  • using at least one hardware processor of a central monitoring computing unit to;

    receive an indication of a detection event via a wireless interface from a detecting sensor of a plurality of motion sensors connected to said central monitoring computing unit, said detection event being for a detecting space of a plurality of monitored spaces of a monitored site that is monitored by said detecting sensor;

    instruct, in response to reception of said indication of said detection event via said wireless interface, a transmitter to transmit a wireless request message to all of said plurality of monitored spaces of said monitored site respectively monitored by said plurality of motion sensors, wherein in response to said wireless request message an identification device in said detecting space transmits a unique identification signal;

    estimate an identity of a person carrying and/or wearing an identification device in said detecting space of said detecting sensor of said plurality of motion sensors by analyzing said unique identification signal transmitted by said identification device in response to said wireless request message and captured by an RF receiver of a plurality of RF receivers which was selectively enabled from said plurality of distributed RF receivers based on said RF receiver having a reception coverage area that overlaps with said detecting space; and

    estimate a location of said person by analyzing a signal strength of said unique identification signal in case a multi-space RF receiver of said plurality of RF receivers has a reception coverage area overlapping with at least two of said plurality of monitored spaces.
