The ST419NG Series is a compact GPS tracker purpose-built for reliable Plaspy-compatible asset and vehicle monitoring. Combining GPRS and LoRa communications with an integrated 900 MHz RF module, the ST419NG offers flexible connectivity for mixed deployments — from urban cellular coverage to low-power wide-area networks and local radio links. Its small form factor, long backup battery and configurable protocols make it a strong choice for fleet management, recovery and concealed installations where dependable real-time tracking and telemetry matter.
Designed for integrators and fleet operators who require an easy Plaspy integration path, the ST419NG Series supports GNSS positioning with LBS fallback, motion sensing and adaptable I/O options across multiple variants (including ST4410 and ST410MG). The device ships with a user manual for installation and configuration, and supports memory download modes (LIFO/FIFO) to optimize data transfer and power usage in remote deployments.
Key Highlights
- Plaspy compatible GPS tracker with GPRS and LoRa channels for versatile connectivity and reliable real-time tracking.
- Integrated 900 MHz RF module for local radio links and recovery workflows where short-range communication is needed.
- Built-in 2,700 mAh backup battery supports extended operation during power loss or tamper events.
- Compact form factor (approx. 8.9 x 3.5 x 2.3 cm) suited to concealed vehicle or portable asset installation.
- Motion sensing and configurable I/O interfaces enable telemetry and event-based alerts (variant-dependent).
- Configurable transmission protocols plus LIFO/FIFO memory download modes to balance data usage and battery life.
- LED indicators and an on/off switch simplify commissioning and status checks on site.
How It Works with Plaspy
When integrated with Plaspy, the ST419NG delivers the location and telemetry data you need for operational visibility and anti-theft workflows. Its dual-communication approach lets Plaspy receive frequent real-time tracking updates over GPRS in covered areas, while LoRa provides an alternative low-power path for long-life asset monitoring. The dedicated 900 MHz RF module can handle local radio links such as on-site recovery beacons or asset-to-asset messaging, and configurable transmission protocols help optimize how and when the device reports to Plaspy to save data and battery.
- Real-time GPS location and telemetry updates to Plaspy via GPRS or LoRa.
- Motion-based alerts and event reporting for movement detection and wake-on-motion scenarios.
- LBS fallback provides coarse location when GNSS signals are unavailable, ensuring continuity in reporting.
- Local 900 MHz RF links for short-range communications or recovery assistance integrated into Plaspy workflows.
- Configurable I/O allows event inputs and outputs to be reported to Plaspy; ignition or immobilizer control may be possible when a chosen variant and wiring provide those interfaces.
- Memory download (LIFO/FIFO) ensures Plaspy can retrieve queued logs after connectivity is restored.

- Anti-theft and recovery: concealed installation and 900 MHz RF support to aid recovery; immobilizer or ignition control may be implemented when a variant's I/O supports it.
- Motorcycle and compact vehicle tracking: compact size and backup battery support covert mounting and continued reporting after power loss.
- Asset monitoring and IoT deployments: LoRa and GPRS combination enables long-life asset tracking across mixed connectivity environments.
- Site or yard operations: local 900 MHz links can improve on-site communication between assets and gateways for telemetry aggregation.
Why Choose This Tracker with Plaspy
Choosing the ST419NG Series for a Plaspy-compatible solution delivers practical value: versatile communications (GPRS, LoRa and a 900 MHz RF channel) reduce single-point connectivity risk, while the 2,700 mAh backup battery and motion sensing help maintain reliable telemetry during power interruption or tamper events. Its compact form and configurable I/O options support discreet installations for fleet management, recovery and anti-theft workflows. Because the device supports configurable transmission protocols and memory download modes (LIFO/FIFO), integrators can tailor data reporting to Plaspy for optimal power, data usage and reporting cadence, enabling scalable, trustworthy GPS tracker deployments across mixed vehicle and asset fleets.
