Comprehensive program helps intended victims and the authorities that protect them

Domestic violence offenders return and attack their victims all too often*. Protection orders alone may not be enough to prevent a repeat attack. The Domestic Violence Monitoring program from Sentinel gives victims extra peace of mind and law enforcement another tool in this important effort.

How it works

The victim voluntarily carries a small and discreet GPS tracking device. The offender is court-ordered to wear a GPS ankle bracelet at all times. Advanced GPS monitoring technology tracks the location of both the offender and their intended victim.


A Mobile Exclusion Zone (MEZ) follows the tracking device carried by the victim.  Sentinel compares location data from the victim and offender. Should the offender approach within a preset distance, from thousands of feet to tens of miles, an alert is triggered.


Specially trained operators in Sentinel’s National Monitoring Center notify the targeted individual and law enforcement. The victim is given the appropriate guidance and ample time to get to a safe and secure location. The offender’s location is tracked and they can be held accountable for their actions. Contact between intended victim and offender is avoided
