Queclink GV51MG — Product and Deployment Information
The Queclink GV51MG is a slim LTE Cat M1/NB1 GNSS tracker for automobile finance, rental and leasing, fleet monitoring and stolen vehicle recovery. It supports AES-256 encryption, basic digital I/O and a configurable I/O.
Queclink lists GV51MG on its End-of-Life page. Contact Tracking Hardware UK to confirm remaining stock, lifecycle support and a suitable alternative before specifying it for a new project.
Tracking Hardware UK supplies GV51MG for B2B projects. We can help check the exact hardware version, destination network, receiving platform, installation requirements and current availability before you order.
Key Specifications and Deployment Notes
Cellular: LTE Cat M1/NB1 with 2G fallback. Match the exact device bands, SIM service and operator support to the destination; fallback requires an available compatible network.
GNSS: Qualcomm GNSS receiver, as listed in the linked manufacturer datasheet. Confirm the hardware revision for receiver-specific requirements.
Encryption: AES-256 support. Confirm the required firmware, configuration and receiving-platform integration; support alone is not a complete system-security guarantee.
External supply: 8–32 V DC.
Backup battery: 190 mAh Li-Polymer.
Dimensions and weight: 87 × 55 × 12.5 mm; 95 g.
Operating temperature: −30°C to +80°C.
Interfaces and monitoring: Positive-trigger digital input, open-drain digital output, configurable negative input/output and TTL UART for configuration. Scheduled reports, geofences, tow alerts, crash detection and up to 10,000 buffered messages.
Frequently Asked Questions
Is GV51MG suitable for a new deployment?
Queclink lists GV51MG on its End-of-Life page. Contact Tracking Hardware UK to confirm remaining availability, lifecycle support and an alternative appropriate for the project before ordering.
How does GV51MG differ from GV53MG?
The linked manufacturer datasheets list GV51MG as LTE Cat M1/NB1 and GV53MG as LTE Cat M1/NB2. Check the exact hardware, supported bands, firmware, platform and lifecycle requirements when selecting a replacement.
Does GV51MG support encrypted data?
The manufacturer lists AES-256 encryption support. Confirm the device firmware, configuration and receiving-platform integration for the intended deployment.
Can I use a driver identification keypad?
The linked datasheet lists digital I/O and TTL UART, but does not list BLE or 1-Wire. Send the exact proposed pairing and interface requirements for a compatibility check.
Does GV51MG have a backup battery?
Yes. The linked manufacturer datasheet lists a 190 mAh Li-Polymer battery. Backup runtime depends on signal conditions, reporting frequency, temperature and configuration.
Can I request a quote for replacements or existing installations?
Yes. Send your installed model and revision, quantity, destination and platform to Tracking Hardware UK so remaining stock, support and suitable alternatives can be checked.
