Terrafirma Tracker



Terrafirma trackers are GPS/GPRS based motion sensor security system that provides: pinpoint tracking accuracy, automated responsive alert notifications, unparalleled service levels and the best customer controls on the market.

Our proactive system will activate and alert the user the moment any disturbance is detected in the vehicle.

Movements without the key in the ignition, forced entry through doors or windows, or if your vehicle leaves a predetermined geo-zone, will all trigger the device. Through the use of our mobile app, we have such confidence in our visual live feed tracking system that your vehicle will be recovered. Our product is unique because it combines monitoring and other various features that are controlled via our personalised mobile app.

Our system can be fitted in to any vehicle with all features working to full effect. Not only a tracking device but also an all inclusive security system.

An all-inclusive proactive security system designed to stop criminals at source and guard your vehicle from theft. With the mobile app you can proactively monitor any unauthorised activity and the location of your vehicle 24/7. A combination of inbuilt motion sensors and GPS technology result in immediate alerts (SMS/Phone call/App notifications) directly to your mobile phone in any moment any unlawful activity is detected. Trigger points include internal vibration, vehicle movement, keyless ignition or battery disconnection. Rest assured, if all these alerts go unheard, the proactive tracker has a remote-control isolator switch and all the tracking capabilities you come to expect from a product of this nature.
