Overview

Modern vehicle theft has evolved beyond conventional alarm systems. The Teltonika Security TSec alarm system integrates directly with your vehicle's CAN and LIN bus — communicating with the factory ECU to block engine start at the firmware level. This method cannot be defeated by cutting wires, cloning key fobs, or physically removing the device. Combined with built-in GNSS tracking, integrated GSM connectivity, shock and tilt sensors, and real-time mobile monitoring, this is enterprise-grade vehicle protection compatible with 700+ vehicle models — installed and commissioned by our Nairobi-based team.

How It Works

From installation to insight — step by step

01

CAN/LIN Bus Integration

The TSec device connects directly to the vehicle's CAN and LIN bus lines with no spliced wires and no relay boxes. Pre-mapped profiles for 700+ models ensure clean, invisible integration with the factory ECU and locking systems.

02

ECU-Level Immobilisation

The immobiliser blocks engine start at the ECU firmware level — not via a physical relay that can be bypassed. Even if the device is disconnected, the ECU remains locked until the TSec system authorises release.

03

Sensor Monitoring & Alarm Activation

Integrated shock sensors detect impacts and forced entry. Tilt sensors trigger immediately if the vehicle is lifted, towed, or wheels are removed. Any event activates the siren and dispatches instant alerts.

04

Real-Time Tracking & Remote Response

Built-in GNSS and GSM enable continuous location tracking, instant push/SMS alerts, and remote commands — arm, disarm, lock, unlock, or trigger engine cut — directly from the Teltonika Security mobile app.

Key Features

Everything you need in one solution

CAN/LIN Dual Bus Integration

Direct integration with the vehicle ECU via CAN and LIN bus — no additional relays, no visible wiring, seamless compatibility with factory security systems.

ECU-Level Immobilisation

Engine start is blocked at the ECU firmware level. Disconnecting the device does not remove the lock — the ECU stays blocked until TSec authorises release.

Built-In GNSS Tracking

Integrated GNSS module delivers real-time vehicle location, trip history, and theft recovery coordinates — all accessible directly in the mobile app.

Built-In 4G/GSM Connectivity

Onboard GSM module transmits alerts, location data, and remote commands without requiring a separate GPS tracker device.

Shock & Tilt Sensors

Integrated shock sensor reacts to impacts and break-in attempts. Tilt sensor triggers immediately if the vehicle is lifted, towed, or wheels are removed.

Teltonika Security Mobile App

Arm and disarm the alarm, lock and unlock doors, trigger remote engine start where supported, and monitor all alarm events in real time from a single app.

Multi-Channel Instant Alerts

Push notifications and SMS alerts with GPS coordinates dispatched the moment a sensor trigger, forced entry, or movement event is detected.

700+ Vehicle Model Compatibility

Pre-mapped CAN/LIN profiles covering 700+ vehicle models across major global manufacturers ensure reliable, factory-grade integration on any fleet.
