Radio Frequency (RF) Tether
The Radio Frequency system consists of a transmitter, worn on the offender’s ankle, and a receiver which is placed in the offender’s home. The transmitter communicates with the receiver, which has a pre-set distance range the offender must stay within during the times they are scheduled to be home.
All transmitters are water resistant and have dual tamper detection, strap and body tampers. The receiver communicates via the home telephone line to our monitoring center and reports all leaves, returns, fail to returns, tampers, power failures and phone line problems as they occur.
