Sierra Wireless - OMM400


Electronic Monitoring Device

The OM500 is a versatile, one-piece, GPS/cellular ankle-worn electronic monitoring bracelet with 2-way communication. The OM500 was designed to track—and communicate with— all types of offenders 24/7, indoors and outdoors. The OM500 signals offenders using vibrations and sound, and receives offender acknowledgment in return.

The OM500 can pair with Sierra Wireless’s optional RF Beacon to extend battery life and precisely verify in-home locations. OM500 uses the cloud-based software application, FocalPoint®, to visualize, map, and track offender movements and locations.
