Exclusive Accessories


Since the ReliAlert device demonstrates such outstanding GPS performance, in most cases a beacon is not necessary and is only used if GPS reception has proven to be insufficient. If a location that an offender regularly visits, such as home or work, has insufficient GPS coverage, a beacon may be used to ensure location information via the beacon’s RF location reporting functionality.
