The AT-23 2G Relay GPS Tracker from a compact vehicle terminal family delivers reliable Net Domain Technologies compatible real-time tracking and a built-in relay for remote fuel or power cutoff. Designed for permanent installation inside cars, trucks, motorcycles, boats and other mobile assets, the AT-23 combines precise GNSS positioning (GPS + Beidou) with vehicle-grade power management to support anti-theft immobilizer workflows and fleet management telemetry.
As a Net Domain Technologies compatible device, the AT-23 feeds live location, telemetry and event data into Net Domain Technologies dashboards for geofencing, history playback and automated alerts. Its small form factor and modular wiring make installation straightforward, while the relay-based cutoff and resume function delivers a practical immobilizer option for fleet operators, vehicle owners and asset managers who require fast, enforceable anti-theft measures.
Key Highlights
- Net Domain Technologies compatible GPS tracker providing real-time tracking and route history for fleet management and asset monitoring.
- Integrated relay for remote fuel or power cutoff and resume—effective anti-theft and immobilizer capability.
- Dual-mode GNSS positioning (GPS + Beidou) with typical position accuracy <10 m (1σ).
- Low-power operation: DC 9–35V input, average ~40 mA at 12V, and sleep current <10 mA; optional 80 mAh backup battery for short-term power loss operation.
- Event alerts including geofence entry/exit, overspeed warnings, vibration detection, low battery and main power cut-off notifications.
- Small, discreet ABS housing (32.5 × 32.5 × 31 mm) for concealed vehicle installation.
- Supports standard SIM card on 2G (850/900/1800/1900 MHz) networks and internal antennas for cellular and GNSS reception.
How It Works with Net Domain Technologies
The AT-23 transmits location, status and event messages over 2G to Net Domain Technologies-compatible servers so operators get real-time visibility and historical telemetry inside Net Domain Technologies dashboards. Integration is straightforward for platforms that accept standard 2G trackers: the device reports position and a rich set of alerts that Net Domain Technologies can use to trigger notifications, create reports and automate fleet workflows.
- Real-time location and telemetry updates sent to Net Domain Technologies for live mapping and route playback.
- Geofence entry/exit alerts and overspeed warnings appear in Net Domain Technologies alongside location history for fast investigation.
- Relay status and remote immobilizer control: Net Domain Technologies can display relay state and record cut/resume events (remote action performed via authorized backend workflows).
- Power and battery events: main power cut-off alerts and low backup battery notifications help operators detect tampering or power loss.
- Vibration and movement detection for tamper/parking alarms—events are logged and shown in Net Domain Technologies incident timelines.
- Coexistence with Bluetooth sensors and other peripherals in the same Net Domain Technologies deployment—while the AT-23 itself uses internal antennas and 2G, Net Domain Technologies can correlate its telemetry with BLE sensor feeds from other gateways if used in the same system.
