4G Relay GPS Tracker for Cars

The 4G Relay GPS Tracker is a concealed vehicle tracking device designed with the appearance and installation structure of a standard automotive relay. Its discreet design allows it to be installed inside a vehicle relay box or another hidden wiring area, making it difficult to discover or remove.

The tracker combines GPS and BeiDou dual-satellite positioning, cellular data transmission and vehicle status detection. Vehicle owners and fleet managers can view real-time locations, historical routes, ignition status and alarm records through an Android app, iOS app or web-based tracking platform.

Hidden Relay-Style Installation

A conventional GPS tracker may be easily recognized during vehicle inspection. This product uses a compact relay-style enclosure that integrates naturally with automotive electrical components.

The concealed installation design is particularly useful for vehicle anti-theft protection, rental fleet management, vehicle financing and other applications that require discreet location monitoring.

GPS and BeiDou Dual-Satellite Positioning

The device supports GPS and BeiDou positioning for stable outdoor vehicle tracking. A built-in ceramic antenna improves satellite signal reception without requiring a visible external GPS antenna.

AGPS can assist with faster initial positioning when cellular network data is available. LBS positioning can provide an approximate location when the vehicle is temporarily inside a weak satellite-signal environment.

Real-Time Vehicle Monitoring

After installation, the relay GPS tracker transmits location data through a 4G LTE or compatible cellular network. The platform can display the vehicle’s latest position, speed, movement direction, positioning time and online status.

The reporting interval can be configured according to different tracking, data-consumption and fleet-management requirements.

Optional Remote Engine Cut-Off

The relay-control version can be connected to a suitable vehicle control circuit for authorized remote fuel or power interruption. This function may help prevent unauthorized vehicle use or support vehicle recovery after theft.

For safety, remote cut-off commands should only be performed when the vehicle is stationary or travelling at a safe, low speed. Installation must be completed by a qualified automotive electrician, and the control circuit must match the vehicle’s electrical system.

ACC Ignition Detection

The ACC input detects whether the vehicle ignition is switched on or off. Fleet managers can use this information to review driving time, parking duration, unauthorized use and daily vehicle activity.

ACC status also helps the tracking platform distinguish between normal parking, active driving and abnormal movement.

Geo-Fence and Vehicle Alarms

Users can create virtual boundaries around parking areas, warehouses, cities, approved routes or customer locations. The platform can generate an alert when the vehicle enters or leaves a configured area.

Depending on firmware and platform settings, the tracker can also support overspeed, vibration, abnormal movement, external power disconnection and device-offline alerts.

Historical Route Playback

The tracking platform stores historical location records for authorized review. Users can check travel routes, stop locations, driving periods, vehicle speeds and previous alarm events.

Route history is useful for logistics verification, fleet dispatching, rental management and investigation of unauthorized vehicle movement.

Mobile App and Web Platform

The relay GPS tracker works with Android and iOS mobile applications as well as a browser-based management platform. Individual users can monitor one vehicle, while fleet operators can manage multiple devices from a centralized account.

Available platform functions can include real-time tracking, device lists, route playback, geo-fence configuration, alarm reports, ACC status and remote command management.
