VT904 Security Upgrade Pack | Enhanced Immobilizer & Alarm System Expansion Kit

This comprehensive Security Upgrade Pack (SP904) is designed to seamlessly integrate with your existing 4G VT904 GPS Tracker, transforming it into a powerful, interactive security command center. By connecting your vehicle's alarm system to the VT904, you unlock advanced remote immobilization and real-time alert features, providing proactive control and peace of mind.

Key Features & Capabilities:

• SMS Siren Alert Notification: Connect your vehicle's existing aftermarket alarm siren output to the VT904. When the alarm is triggered, the system automatically sends an SMS text alert directly to up to two pre-programmed mobile numbers. The message includes an SOS ALERT with a direct link to your vehicle's real-time GPS location on a map.

• Remote Engine Starter Immobilization: Via the dedicated mobile app or SMS command, you can remotely activate or deactivate an installed relay to immobilize the vehicle's starter motor, preventing unauthorized engine starts. (Requires professional installation of a relay on the starter circuit).

• Dedicated SOS/Panic Button: The kit includes a button that can be installed for manual triggering. When pressed, it sends the same immediate SOS alert with live location to your designated contacts.

• System Integration: Designed to connect with most aftermarket alarm systems (e.g., Mongoose) that have a siren trigger output. If no alarm is present, a complete Mongoose security system can be added to enable these features.
