Navtelekom - SMART S-2420

The SMART S-2420 from Navtelecom is a compact, entry-level GLONASS/GPS vehicle tracker that is Plaspy compatible and designed for straightforward vehicle monitoring where cost, simplicity, and reliable positioning matter. With integrated sensitive GLONASS/GPS and GSM antennas, a single-SIM 2G modem, and Bluetooth 4.0 for local configuration, the S-2420 provides the fundamental telemetry and I/O capabilities fleet operators and service providers expect for basic tracking, route logging, and anti-theft workflows.

The SMART S-2420 is ideal for permanent vehicle installations that rely on vehicle power (the unit has no internal battery). It exposes three universal configurable inputs and two control outputs for sensor and actuator integration, and includes hardware power protection and input-line protection up to 200 V. As an archived/discontinued model, documentation and firmware history remain available through Navtelecom’s downloads and DRC portal, but firmware support is limited compared with current product lines.

Key Highlights

• Plaspy compatible GPS tracker suited for cost-conscious fleet management and basic asset tracking.
• Built-in sensitive GLONASS/GPS and GSM antennas simplify installation—no external antenna cabling required.
• 2G GSM modem with single SIM support for standard real-time tracking and telemetry reporting (verify regional 2G availability).
• Bluetooth 4.0 for local configuration and interaction with Bluetooth sensors or setup tools.
• Three universal configurable inputs for digital sensors, ignition detection, or fuel sensor interfaces.
• Two control outputs to drive relays, immobilizer circuits, or other actuators for anti-theft and remote control.
• Robust power protection and input line protection up to 200 V for vehicle electrical environments.

How It Works with Plaspy

The SMART S-2420 integrates with Plaspy through standard Navtelecom communication protocols, enabling Plaspy to receive location fixes, basic telemetry, and digital I/O states for real-time tracking and reporting. Plaspy uses the device’s 2G uplink for position and telemetry packets; Bluetooth 4.0 is available for on-site configuration during installation or maintenance.

• Real-time location and telemetry updates delivered to Plaspy via the 2G modem (subject to network availability).
• Ignition and digital input states reported through configurable inputs—useful for engine-on/off events, door sensors, or alarm triggers.
• Fuel monitoring and other telemetry when compatible sensors are connected to the universal inputs and mapped in Plaspy.
• Remote immobilizer or actuator control supported by Plaspy using the tracker’s control outputs (requires proper configuration and relay wiring).
• Bluetooth 4.0 for local configuration, diagnostics, and optional Bluetooth sensor discovery during setup.

Technical Overview

Use Cases

• Fleet management for light vehicles where low-cost, Plaspy compatible real-time tracking and route logging are required.
• Basic anti-theft monitoring with relay-based immobilizer control via the device’s control outputs.
• Remote status monitoring (ignition on/off, door/open alarms) using configurable inputs for event-driven alerts in Plaspy.
• Simple telemetry and fuel monitoring when a fuel sensor is connected to the universal inputs and integrated into Plaspy’s reporting.
• Asset tracking and location logging where permanent vehicle power is available and minimal hardware footprint is desired.

Why Choose This Tracker with Plaspy

The SMART S-2420 offers a pragmatic balance of essential GPS tracking features and Plaspy compatibility for deployments that prioritize affordability and straightforward integration. Its sensitive integrated GNSS/GSM antennas reduce installation complexity, and the configurable inputs and control outputs allow Plaspy-based workflows for basic telemetry, ignition detection, and remote immobilization. For organizations that need a compact, entry-level GPS tracker for fleet management, route logging, or anti-theft functions, the S-2420 remains a viable archived option—provided you confirm regional 2G network availability and accept the limited support lifecycle associated with an archived model.

Before deploying at scale, verify 2G network compatibility in your region, confirm any required wiring for ignition or immobilizer functions, and review the Navtelecom downloads/DRC portal for available documentation and firmware history. When paired with Plaspy, the SMART S-2420 delivers reliable basic tracking, telemetry and local Bluetooth configuration for cost-sensitive vehicle monitoring projects.
