TRACKER is set to launch an enhanced version of its stolen vehicle recovery service with the arrival of a round the clock monitoring system. Targeted specifically at commercial vehicles, Tracker's 24 Hour Monitor automatically alerts owners as soon as their vehicle is stolen.

The system is based on a movement detector linked to an immobiliser system, which immediately alerts the Tracker network if the system is illegally bypassed. Tracker then contacts the customer to confirm whether the vehicle has been stolen and activates the on-board Tracker unit which can then be picked up by police cars and helicopters.

With almost 100,000 Tracker units in operation, the police have recovered 1,400 stolen vehicles fitted with Tracker and made more than 500 arrests. The 24 Hour Monitor costs an additional £175 over Tracker's standard £170 lcv system and at £78, the network subscription costs an extra £26 a year.
