Indoor Positioning

Indoor Positioning System
There is an increasing demand to provide accountability and traceability in the supervision of routine security tasks based upon our hermesTRX MOTOTRBO fleet management system. The hermesTRX family has been enhanced to provide both indoor and wide area Guard Control traceability. Not only does this solution provide Guard Control, but it can also be utilized to provide man down functionality further enhancing the safety of the guard.

Indoor Tracking compliments Wide Area Tracking

Indoor tracking is accomplished by the installation of a number of beacons throughout the various areas of a building or large complex. The beacon is fitted with an ISM transmitter, which broadcasts a unique ‘signature’ up to a distance of approximately 25 meters around the beacon. The hermes transponder option board is fitted with a corresponding ISM band receiver, which automatically picks-up the beacon’s signature as it is moved around the complex. The hermes transponder option board automatically instructs the radio to send the beacon ID to the hermesTRX dispatch station where the location of the subscriber is updated on the screen. In the event of an emergency, the location of the ‘downed’ person will be displayed in red on the screen.


Advanced Patrol Management

By placing beacons close to checkpoints which need to be visited by security guards, the hermesTRX beacon is ideally suited to provide verification that a check has actually taken place. The supervisor of a group of security guards can specify a particular route for each individual guard. Each time a guard checks a particular checkpoint the hermesTRX is updated with their progress, this ‘check’ is timestamped in the log. Should the guard fail to check aparti cular checkpoint in their designated route, an alarm will be given to the dispatcher, similarly, if the guard checks a checkpoint out of turn, or is delayed in arriving at a particular checkpoint, the dispatcher will receive an alarm. The hermesTRX Guard Control can be used to verify guard’s activities in both a wide area or a small complex.


The Beacons

The hermesTRX beacons have a coverage range which ranges from 1 meter up to 25 meters (1-75 ft). The output power can be adjusted as necessary to define the required coverage range. The beacons an be supplied in 3 variants for indoor, outdoor and flush mount variants. To eliminate failure of a beacon due to low battery power, the MOTOTRBO automatically send the actual battery power of the beacon each time the beacon ID is transmitted to the hermesTRX.
