A self-contained one-piece GPS ankle monitor that replaces daily charging with weeks of unattended operation. Both ONE and ONE-AC models support WiFi-directed mode (~3 weeks battery, plus dead-zone coverage), while ONE-AC adds BLE-connected mode reaching 6 months. At 108 grams with fiber-optic anti-tamper detection producing zero false alarms, it is the lightest and most reliable one-piece device available for corrections, pretrial, and immigration programs.
Request a QuoteTraditional GPS ankle monitors burn through batteries in 24–72 hours because they run GNSS and LTE continuously — even when the participant is sleeping at home. Both CO-EYE ONE models change this with multiple operating modes that activate automatically:
WiFi-directed mode (both ONE and ONE-AC): Routes data through WiFi instead of LTE — extending battery to approximately 3 weeks while simultaneously covering cellular dead zones. A $10 WiFi repeater is all it takes.
BLE-connected mode (ONE-AC only): Pairs with the smartphone app or HouseStation and offloads all high-power operations — extending battery to approximately 6 months.
LTE standalone (both models): Full GNSS + cellular tracking for about 7 days — still 3–10× longer than most competitors.


GPS alone fails indoors, in basements, and in rural dead zones. The CO-EYE ONE stacks five independent positioning methods so there is always a fallback:
• Four-constellation GNSS (GPS + BeiDou + GLONASS + Galileo) — sub-2-meter outdoor accuracy
• WiFi positioning — 10–30m indoor location plus dead-zone data backhaul
• BLE proximity — confirms presence near smartphone or HouseStation without any GPS or cellular
• Cellular LBS — coarse location when GNSS is unavailable
• HouseStation verification — positive in-home confirmation for curfew programs
Built-in anti-spoofing monitors GNSS carrier-to-noise ratios and satellite constellation consistency to detect jamming and fake GPS signals.
A 500-enrollee program using 48-hour devices processes 50–100 low-battery alerts per day. Both CO-EYE ONE and ONE-AC run ~3 weeks on WiFi-directed mode; the ONE-AC reaches 6 months in BLE mode. Officers manage supervision instead of managing chargers.
Place a $10 WiFi repeater in a basement apartment or rural home. The device automatically routes data through WiFi instead of LTE — solving the coverage problem and extending battery life simultaneously. One fix, two results.
Fiber optic continuity on strap and case delivers binary tamper evidence without the 15–30% false-positive noise common to skin-sensing loops. Optional steel cut-resistant strap protects high-risk caseloads; 3-month+ tamper awareness remains after battery depletion.
Patented snap-on design delivers 3-second tool-free installation and removal—no torque drivers or strap presses in the field. Pre-configured S/M/L/XL TPU fiber optic straps preserve tamper evidence from the first click.
At 108g in a 60×58×24mm footprint, CO-EYE ONE is the lightest one-piece GPS ankle monitor in its class—40–55% lighter than typical 150–252g alternatives—improving comfort, stigma, and long-shift wearability.
Future-proof cellular with 5G compatible LTE-M/NB-IoT/GSM, dual-path connectivity, and ONE-AC eSIM + Nano SIM management. HTTPS/SSL, AES128/256 transport, and CyberSecurity EN 18031 certification keep data paths hardened.
