CO-EYE i-Bracelet / i-Tracker

CO-EYE i-Bracelet / i-Tracker - 1

Two-Piece GPS Electronic Ankle Bracelet & Tracking Device

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.

The smallest ankle bracelet for law enforcement

The smallest ankle bracelet for law enforcement

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.

Main Features

Simple to install

Quick and simple installation and activation procedure using custom tools for a secure fit every time.

Tamper protected solution

Multiple detection mechanisms on the Two-Piece GPS unit and the participant's body-worn transmitter provide electronic and physical evidence of tamper attempts.

Reliable communication

Data transfer to the monitoring center supports HTTPS connection, or proprietary protocols using AES encryption for authentication and validation.

Advanced tracking methods

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.

Flexible program configuration

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.

Multiple data communication options

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.

Frequently Asked Questions

What is a two-piece GPS ankle monitor?
A two-piece system separates the wearable component (i-Bracelet, worn on the ankle) from the tracking hub (i-Tracker). The bracelet communicates with the tracker via BLE/433MHz radio. This design allows larger batteries in the hub and enables home-based or vehicle-based monitoring configurations.
How does the i-Bracelet communicate with the i-Tracker?
The i-Bracelet uses both BLE (Bluetooth Low Energy) and 433MHz radio to maintain a constant connection with the i-Tracker hub. The 433MHz range reaches 20m indoors and 100m outdoors for the standard i-Tracker, or 50m/200m for the i-Tracker Plus with phone functions.
Can the i-Tracker work as a standalone GPS tracker?
Yes, the i-Tracker functions as a full GPS tracking device with its own GPS, cellular (3G WCDMA / 2G GSM), WiFi, and battery. It can be used independently for asset tracking or paired with the i-Bracelet for offender monitoring.
What anti-tamper technology does the i-Bracelet use?
The i-Bracelet uses optical fiber anti-tamper detection embedded in the strap, delivering a zero false-positive rate. Any physical cut or break in the fiber immediately triggers a tamper alert to the monitoring center — with no false alarms from skin contact loss, sweat, or environmental factors.
