Vehicle Theft & Tampering Alerts: How GPS Keeps Your Assets Safe

Modern GPS tracking goes well beyond simply showing you where a vehicle is. Sophisticated alert systems can detect suspicious activity around your vehicles — even before a theft is fully underway — giving you the best possible chance of preventing losses.

What counts as tampering?

Tampering takes many forms. It might be someone testing door handles, attempting to access the OBD port to clone keys, draining fuel from a tank, or disconnecting a battery to disable a tracker. Each of these events can be detected and reported by a properly configured GPS tracking system.

Movement and ignition alerts

The most fundamental anti-theft alert is a movement notification — triggered the moment a vehicle moves without the ignition being started in the normal way. This catches tow-away thefts, vehicle roll-aways, and any unauthorised physical movement.

Ignition alerts notify you the moment a vehicle's engine is started — useful for detecting key theft or relay attacks on keyless entry systems.

Fuel drain detection

For fleet vehicles and heavy machinery with large fuel tanks, fuel theft is a significant and ongoing problem. TrackVision Tech's Premium plan includes fuel drain detection — if the fuel level drops abnormally outside of normal operational patterns, an alert is triggered immediately.

Door open and trailer disconnect alerts

Sensors can detect door openings and trailer decoupling events — useful for cargo vehicles where access to the load area outside of expected times could indicate theft in progress.

Geofencing as a first line of defence

Setting up a geofence around a vehicle's usual overnight location means any movement outside that zone — however slight — triggers an immediate alert. This is particularly effective for forecourt vehicles, construction equipment, and any asset stored in a fixed location overnight.
