  • VHF (Very High Frequency) is the technology that Tracker uses to track and locate stolen vehicles. This addresses the problem of signal jamming that can affect GPS and GSM systems to ensure jammers cannot disable Tracker systems.


    VHF technology also aids location of concealed vehicles and is effective at finding even those hidden in shipping containers, garages or underground car parks.

  • Global Positioning System (GPS) is a constellation of satellites providing location and time information anywhere where there is an unobstructed line of sight to four or more GPS satellites. Tracker use GPS in helping to locate vehicles.

  • GSM stands for Global System for Mobile Communications and is the standard used to describe technologies for second generation (2G) digital cellular networks. Tracker uses GSM to communicate with the Tracker systems.

  • Tracker Locate, Tracker Cat 5 Plus, Tracker S5 Plus or Tracker Plant fitted vehicles listen out for the messages or reply codes being sent out by stolen SVR fitted vehicles. When a vehicle installed with Tracker Locate, Tracker Cat 5 Plus, Tracker S5 Plus or Tracker Plant passes a stolen vehicle, it picks up the reply code and sends its position to the Tracker Control Room. Importantly, the driver of the listening vehicle will have no idea that their car has helped identify a stolen vehicle, and equally, the driver of the stolen vehicle won’t know they are being tracked either.

    Please note: the Tracker subscription is non-transferable; therefore your subscription cannot be transferred to the new owner if you sell your vehicle. 

  • No. A major security feature of the system is that the presence of the Tracker system is not disclosed to the thief. In fact, identification stickers are an encouragement to thieves to damage the vehicle, as they may hurriedly attempt to locate the system. 

  • No.  For security reasons and avoidance of any possible false alarms, the Tracker system stays with the original vehicle for its lifetime.  When you sell your vehicle, the new owner can benefit from the Tracker system once he or she has registered with Tracker and paid the subscription and registration fees.
