The OM400 is a one-piece GPS/Cellular offender monitoring ankle bracelet specifically to track low to high-risk offenders 24/7, indoors and out. The OM400 allows you to signal offenders using vibrations and sounds and receive offender acknowledgement in return. Built on the rock-solid reliability of the popular OM210, the OM400 continues to provide reliable tracking services.

This device can also be used in domestic violence programs in which both the offender and victim are issued an OM400. Both devices are simultaneously tracked by our 24/7/365 National Monitoring Center. If the victim and the offender come within a predetermined distance from each other, our personnel can contact the victim directly to provide notice of the offender’s proximity.
