Guardforce’s wireless bed exit alarm system uses radars to detect movements. A leave bed alarm will sound when a person being monitored leaves his or her bed. Radar technology is also used to power a solution for fall risk management. The fall detection alarm system can be applied at elderly care facilities in Hong Kong for constantly monitoring senior residents who face greater risk of falling over and hurting themselves. The latest model has added multiple functions. In addition to detecting leaving the bed/designated space and falling, it can also detect motionless, long- stay, occupancy and people counting.
