The OM400 is a versatile, one-piece, GPS/cellular ankle-worn electronic monitoring bracelet with 2-way communication. The OM400 was designed to track—and communicate with all types of offenders 24/7, indoors and outdoors. The OM400 signals offenders using vibrations and sound, and receives offender acknowledgment in return.

The OM400 can pair with Omnilink’s optional OM400 RF Beacon to extend battery life and precisely verify in-home locations. OM400 uses the cloud-based software application, FocalPoint®, to map and track offender location.
