RadarFind's plug-in readers are part of a distributed sensor-network-based system. Intelligent RTLS tags continuously communicate wirelessly with readers placed throughout a hospital facility to report location, status, contextual awareness and environmental conditions regarding medical devices and people. A pass-through design accommodates most electrical outlets, yet preserves electrical sockets for use by other medical equipment. RadarFind offers hospitals their choice of electrical socket colors to match existing outlets, including red receptacles to indicate outlets that are powered by back-up generators in the event of an electrical power outage. Tamper-resistance enhancement complies with NEC safety standards.
