Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • GPS Tracking & Anti-Jamming: Equipped with 4G and anti-jamming technology for real-time vehicle location tracking, ensuring reliable connectivity even in signal-challenged areas.
  • Bluetooth Relay Engine Cut-off: The relay module (40A, 12-24V) enables remote engine shutdown via Bluetooth, enhancing vehicle security against theft or unauthorized use.
  • Geo-Fence Alarms: Alerts users when a vehicle enters/exits predefined boundaries, supporting proactive monitoring for fleet management or personal use.

Key features

  • 1. Anti-Jamming GPS Technology

    • With advanced anti-jamming GPS capabilities, you can ensure uninterrupted tracking even in signal-obstructed environments. This technology outperforms standard GPS trackers prone to interference*, providing reliable location data for commercial or high-risk scenarios.

  • 2. Bluetooth Relay for Remote Engine Control

    • With integrated Bluetooth relay functionality, you can remotely trigger engine cutoff or control vehicle systems via a smartphone app. This eliminates the need for physical access, offering greater security compared to wired systems*.

  • 3. 4G Connectivity & High Current Handling

    • With 4G network support and a 40A relay capacity, you can achieve faster data transmission speeds (~50% quicker than 2G models*) and manage heavy-duty electrical loads, such as engine shutdowns or powering large accessories.

  • 4. Geo-Fence Alarms for Scenario-Specific Protection

    • With customizable geo-fencing, you can set virtual boundaries to trigger real-time alerts for unauthorized vehicle movement, ideal for fleet management or personal vehicle security. This feature surpasses basic trackers lacking location-based alerts*.

  • 5. Automotive-Grade Voltage Compatibility

    • With a 12-24V DC operating range, this tracker is certified for compatibility with most vehicle electrical systems, ensuring stable performance in both commercial and personal automotive applications.

  • Notes:

    • The product’s Bluetooth relay and anti-jamming GPS align with its core use case for vehicle security and remote control.

Supplier's note

  1. Technical Breakthroughs:

    • Bluetooth Relay Engine Cutoff: The Pro model’s 40A relay enables instant engine shutdown in theft scenarios, 3x faster than industry-standard relays.
    • 4G Anti-Jamming: The Advanced model’s dual-frequency GPS + GLONASS ensures 99.9% signal integrity in urban canyons.
    • Universal Voltage: The 12-24V compatibility (vs. 12V-only rivals) reduces fleet integration costs by 20%.

  2. Version Selection Guide:

    • Base Model: Ideal for small fleets needing basic tracking (e.g., local taxi services).
    • Advanced Model: Best for medium fleets requiring real-time data (e.g., delivery trucks with 4G coverage).
    • Pro Model: Tailored for high-risk assets (e.g., construction equipment) needing AES-256 encryption and heavy-duty relay capacity.

*Pro Model’s 20Mbps 4G speed is 50% faster than competitors’ 4G trackers.
