The OM400 is a one-piece GPS electronic monitoring ankle-worn bracelet utilized to track low- to high-risk offenders 24/7/365, indoors and out, and relay this information to the monitoring application via cellular communications. The OM400 allows you to signal offenders using vibrations and sounds and receive offender acknowledgment in return.

This device is also used for domestic violence monitoring programs. Devices are simultaneously tracked, and, if the victim and the offender come within a predetermined distance from each other, our National Monitoring Center personnel can contact the victim and designated law enforcement personnel and provide notice based on agency-defined notification protocols.
