BluTag (U.S. Patent RE 39,909 and RE 38,838) is the original one-piece GPS monitoring device that houses its receiver and transmitter in a single unit.
BluTag can monitor the movements of enrollees in active, passive and hybrid GPS modes without changing equipment. The difference between each mode is (a) how quickly the device transmits monitoring data to VeriTracks, our Internet-based monitoring application, and (b) how it transmits monitoring data to VeriTracks.
Differences Between GPS Monitoring Modes
- Active GPS Monitoring: BluTag generates immediate notifications for all events and transmits them to VeriTracks by calling into it using nationwide cellular telephone networks.
- Passive GPS Monitoring: BluTag receives and stores all monitoring data, including violation events, in its onboard memory until the enrollee enters the RF signal range of BluHome.
- Hybrid GPS Monitoring: BluTag generates immediate notifications for inclusion zone violations and tampers. All other event data is stored in the device’s onboard memory until the enrollee (1) charges the battery or (2) the supervising agent/officer initiates a Location Request.
A Location Request occurs when the supervising agent/officer logs into VeriTracks to determine the immediate location of a specific enrollee, regardless of the last time the BluTag device transmitted monitoring data. Only BluTag Active and BluTag Hybrid can provide the immediate location of an enrollee.
Features and Functionality of BluTag in All Monitoring Modes
Over the years, numerous enhancements to its functionality make BluTag a highly effective GPS monitoring device. There are many common features and functionalities of BluTag regardless of the monitoring mode used to supervise an enrollee.
- Shielding GPS signal: BluTag is the only GPS monitoring device capable of detecting, recording and reporting the enrollee's deliberate shielding of the device's ability to receive GPS signals.
- Enhanced Location Technology: BluTag provides increased accuracy of an enrollee’s movements when in a location not conducive to receive GPS signals. BluTag uses data provided by the cellular phone towers to more accurately determine an enrollee’s location.
- Battery: BluTag has the longest battery life of any available GPS monitoring device when receiving one set of GPS latitude and longitude coordinate points each minute. The battery operates BluTag for 60 hours on a single charge and recharging takes only one hour, which is a simple process and can take place in any location that has a standard 110-volt electrical outlet. The battery’s life span is approximately 24 months.
- Specifications: Weight - approximately six ounces; Dimensions - 4.33” x 2.08” x 1.25”
- Tampering: BluTag detects tampering to its strap and case.
- Zones: BluTag can store up to 99 zones in its onboard memory, so it continuously compares enrollee movements to the location of zones to ensure continued compliance.
