The RF Patrol™ electronic monitoring system from Sentinel is one of the most proven and reliable electronic home monitoring units available on the market today.

Used extensively across the U.S. and internationally as well, this two-piece system is comprised of a non-removable radio frequency (RF) PTX2 ankle transceiver and a home-based monitoring unit.

RF Patrol is effective for home confinement monitoring as the ankle transceiver and home monitoring unit continuously communicate with one another to monitor the presence of the participant. The home monitoring unit communicates directly with Sentinel’s 24/7/365 National Monitoring Center to report the participant’s location.

With its simple, durable, and highly cost-effective design, RF Patrol is the monitoring solution of choice for hundreds of agencies across the country. The PTX2 transceiver is water resistant and features a hypoallergenic tamper-resistant fiber-optic ankle strap and a built-in extended-life battery.

Available in landline and cellular models, the home monitoring unit can monitor multiple PTX2 transceivers, making it an ideal solution for supervising participants co-located in “halfway houses” or group housing.

RF Patrol is the feature-rich solution that has become the industry standard for RF monitoring.

  • Small, lightweight durable ankle-worn transceiver
