BluTag® Passive

BluTag® Passive (U.S. Patent RE39,909 and RE 38,838) is the only commercially proven one-piece passive GPS monitoring device on the market today. The receiver and transmitter are housed in a single unit that remains securely fastened around the offender’s ankle. An offender need not carry or plug into any other equipment.
 
BluTag® Passive transmits data using a radio frequency (RF) tether to BluHome™, a GPS accessory, while still attached to an offender’s ankle. Multi-piece passive GPS devices require an offender to remove the transmitter (the component that actually tracks an offender’s movements) every day for up to eight hours to recharge the battery and/or transmit monitoring data. 

Data transmissions
BluTag® Passive receives and stores all monitoring data onboard until the offender enters the RF tether range of BluHome™, a GPS accessory that uses a standard landline telephone connection to transmit data to our Internet-based tracking application, VeriTracks®. BluHome™ installs into an offender’s residence and is powered by plugging into a standard AC electrical outlet.
 
BluHome™ allows customized cut-off points for the RF tether regardless of the layout or construction of the residence. This significantly enhances curfews because the tether can be programmed to cut off at a specified location in or out of the offender’s residence. Traditional electronic tethers remain effective only within a default range and when the layout and/or construction of the residence provides few, if any, obstacles through which the signal must penetrate.

Increased public safety
BluTag® Passive immediately receives GPS coordinates when the RF tether between itself and BluHome™ is broken. Because BluTag® Passive remains securely attached to an offender’s ankle at all times, public safety is enhanced because the movements of an offender are tracked 24/7, even when an unscheduled exit from the residence occurs. BluHome™ sends a violation alert when such an event occurs.
