The CO-EYE ONE is a next-generation one-piece GPS ankle monitor designed for corrections, pretrial, and probation electronic monitoring programs. Weighing just 108g with a 7-day battery life and fiber optic anti-tamper technology delivering zero false positives, it is the most advanced electronic ankle bracelet available.
Request a QuoteThe CO-EYE ONE GPS ankle monitor incorporates a multi-constellation GNSS module (GPS + BeiDou + GLONASS + Galileo) achieving under 2m accuracy. Wi-Fi positioning and cellular LBS provide reliable backup for indoor electronic monitoring scenarios.


Deployed in hundreds of electronic monitoring programs across 30+ countries, the CO-EYE ONE GPS ankle monitor continuously tracks participants in real-time and alerts officers on location or supervision violations. Custom zone restrictions, schedules, and curfew management support every corrections and pretrial monitoring workflow.
Quick and simple installation and activation procedure using custom tools for a secure fit every time.
Multiple detection mechanisms provide both electronic and physical evidence of attempts to tamper with the device. Various levels of strap robustness options are available to meet the needs of the monitoring application and customer requirements.
The CO-EYE ONE incorporates LTE-M/NBIOT/GSM worldwide cellular networks communication – allowing selection of the preferred carrier network and providing redundancy when the primary channel is unavailable.
CO-EYE ONE supports any customized sizes of optical strap or steel-armed optical strap to cover any high-risk offenders usage. With default S/M/L/XL sizes, officers can just go pick-as-use out of box.
Scheduling and zone configuration options to meet the monitoring needs of each agency and monitored individual. Customizable call intervals and GPS sampling rates.
With our innovative patent design, CO-EYE ONE offers 3-second rapid installation and removal at field, and meanwhile keep electronic and physical evidences of tamper attempts.
