RadarFind's Sentry AV real-time location system (RTLS) is a patented enterprise-wide solution for locating and tracking medical equipment and patients. It features active radio-frequency identification alarm capabilities. The wall-mounted device integrates with RadarFind's wireless-sensor network to identify events that will trigger an audio or visual alarm, or both at once, depending on hospital user preference. Users can set an alarm to alert staff via e-mail, pager or a RadarFind-user computer screen; and an audible and visible alert if tagged devices, such as telemetry units, approach a laundry facility, an exit or any other exclusion zone, preventing damage or theft of the unit.
