The JM-VL03 from JM is a compact, discreet 4G LTE Cat 1 GPS tracker designed for fleet managers, insurers and vehicle asset protection teams who need reliable, Plaspy compatible hardware. With LTE communication and GSM fallback, wide input voltage support and a small backup battery, the VL-03 delivers continuous real-time tracking and event-driven telemetry suitable for cars, motorcycles, scooters, industrial vehicles and light equipment.
The VL-03 pairs with Plaspy to provide actionable fleet management and anti-theft capabilities: ignition (ACC) detection, remote immobilizer control via a relay, geo-fence alerts, driving behavior analysis and a suite of instant notifications for device removal, vibration, over-speed and power events. Its rugged IP65 enclosure and GNSS performance make it a practical choice for deployments requiring compact form factor and dependable positioning.
Key Highlights
- Plaspy compatible 4G LTE Cat 1 tracker with GSM fallback for consistent connectivity and real-time tracking across networks.
- Wide 9–90 VDC input range supports virtually all vehicle types—cars, motorcycles, scooters, golf carts and industrial equipment.
- Driver Behavior Analysis detects harsh acceleration, harsh braking, harsh cornering and collisions to improve safety and insurance telematics.
- Remote immobilization (relay) and ignition (ACC) detection enable anti-theft and controlled vehicle shutdown workflows through Plaspy.
- Accurate GNSS positioning (GPS + BDS + LBS) with < 2.5 m CEP and fast TTFF for reliable location updates in open sky conditions.
- Compact, IP65-rated enclosure and wide operating temperature range for outdoor and harsh-environment installations.
- Event-triggered alerts—geo-fence, over-speed, abnormal vibration, low battery and power-off—feed Plaspy for immediate notifications and reporting.
How It Works with Plaspy
When integrated with Plaspy, the JM-VL03 streams location and telematics data over LTE (with GSM fallback) so fleet dashboards, maps and rules engines receive near real-time updates. Plaspy ingests the VL-03’s event triggers and sensor telemetry to power alerts, reports and automated actions such as immobilization or dispatching. Installation is straightforward: connect power and ACC inputs, insert the Micro-SIM, mount the compact IP65 unit and configure device settings in Plaspy.
- Real-time location and telemetry updates for fleet management and live tracking on Plaspy maps.
- Ignition (ACC) status and digital input reporting for ignition-aware workflows and utilization tracking.
- Relay-based remote immobilizer (remote cut-off) support for anti-theft actions initiated from Plaspy.
- Driver behavior events (harsh acceleration/braking/cornering, collision) reported as telemetry events for safety analytics.
- Geo-fence entry/exit, over-speed, vibration and power alerts for instant notifications and rule-based automation in Plaspy.
- Telemetry usable by Plaspy for integration with fuel monitoring or third-party sensors when such systems are combined at the platform level.
