CO-EYE i-Bracelet/i-Tracker two-piece GPS Tracking Unit provides precision location tracking for continuous offender monitoring. A transmitter (i-Bracelet) worn by the monitored person sends signals to the Two-Piece unit to verify their proximity to the tracking unit (i-Tracker). Location data processed and stored by the two-piece unit is transferred over the cellular network or Wi-Fi networks.
Request a QuoteThe Two-Piece GPS device (i-Tracker) incorporates a new-generation integrated GPS module providing highly accurate location capabilities. This is coupled with Wi-Fi location and triangulated cellular Location Based Service (LBS) as backup location methods.


RF i-Bracelet device is the smallest and lightweight professional ankle electronic bracelet, equipped with multiple high-security anti-removal protection mechanisms such as optics, electronics, machinery, and physics. It also provides IP68 waterproof protection.
Quick and simple installation and activation procedure using custom tools for a secure fit every time.
Multiple detection mechanisms on the Two-Piece GPS unit and the participant's body-worn transmitter provide electronic and physical evidence of tamper attempts.
Data transfer to the monitoring center supports HTTPS connection, or proprietary protocols using AES encryption for authentication and validation.
Leveraging multiple satellites systems (supported by GPS, GLONASS, Galileo, and BeiDou), Wi-Fi tracking, and Tower Based Tracking is meticulously designed to provide a location in the most challenging locations.
Scheduling and zone configuration options to meet the monitoring needs of each agency and monitored individual. Customizable local indication (visual, audible and vibration), call intervals and GPS sampling rates.
The i-Tracker incorporates cellular and Wi-Fi communication – allowing selection of the preferred communication platform and providing redundancy when the primary channel is unavailable.
