Queclink GV37CEU

Queclink GV37CEU — Ultra-Low Cost LTE Cat 1 bis Waterproof GNSS Vehicle Tracker

The Queclink GV37CEU is an ultra-compact, ultra-low cost LTE Cat 1 bis fallback 2G waterproof GPS tracker designed for a wide range of vehicle tracking applications. Its extremely compact design — just 81 × 42 × 19mm and 59g — makes it ideal for covert installation in cars, vans, motorcycles and light commercial vehicles where space is limited or discreet placement is critical.

With LTE Cat 1 bis connectivity on EMEA bands (B1/B3/B7/B8/B20/B28) and automatic 2G fallback, the GV37CEU delivers reliable real-time tracking across the UK and Europe. The IP67 waterproof rating ensures durability in outdoor and exposed environments, while BLE 5.4 support enables wireless connectivity to Queclink accessories such as driver identification key fobs. A 9–90V wide voltage input means it wires directly to virtually any vehicle without additional regulators.

As an authorised Queclink distributor in the UK, Tracking Hardware UK ships the GV37CEU directly from our London warehouse — with trade pricing available for telematics service providers, fleet operators and resellers.

Key Features

• Ultra-compact IP67 waterproof design — just 81 × 42 × 19mm and 59g, fully sealed against dust and water ingress for covert or exposed vehicle installations

• Wide voltage input — 9–90V DC operating range covers cars, vans, trucks and commercial vehicles without additional voltage regulators

• Multi-constellation GNSS — all-in-one GPS, BeiDou, Galileo and GLONASS receiver with under 2m CEP accuracy and 1-second hot start for reliable positioning

• BLE 5.4 — wireless connectivity to Queclink BLE accessories including driver identification key fobs and compatible sensors

• Ignition detection — dedicated positive trigger digital input for accurate ignition state monitoring and driving behaviour analysis

• Configurable I/O — one configurable input supporting analog voltage (0–16V) or negative digital input, plus one latched open-drain digital output for relay or accessory control

• Driving behaviour monitoring — built-in accelerometer detects harsh braking, harsh acceleration and crash events with data logging for accident reconstruction and analysis

• Geo-fencing — up to 20 configurable geofence zones with entry/exit alerts and parking violation alarms

• OTA management — remote firmware updates and configuration without physical device access, reducing maintenance costs across large fleets
