Brentwood designed and programmed a GPS radio system using the most advanced technology. They chose Motorola digital radios: portable DP3401s (for handheld use), and mobile DM3401s (for vehicle use). They also selected a desktop radio (used with a PC-based system) for the dispatcher in the office.
The dispatcher can track the exact locations of radio users using the GPS feature – and speak to them at the same time. They also have the option to time-log and voice-record every call made. If someone steals a radio, the dispatcher can even disable its operation, reviving it later (if found again). Brentwood arranges all licensing for the GPS software.
These tough, durable radios allow staff to talk to the whole group, or make private calls to individuals. If they need assistance, they simply press the ‘Emergency’ button to alert their colleagues. As they work in a highly populated area, the radios encrypt all their calls. This feature prevents anyone else picking up their transmissions and eavesdropping.
