GPS Jammers and Your Car Tracker

How jammers are used in car theft

Thieves switch on a jammer during a hijacking or theft so the tracker cannot report the vehicle’s location, then move the car to a hiding place. Remote-jamming is also used in parking lots to stop central locking from working, leaving the car unlocked.

How trackers fight jamming

• Jamming detection: the unit notices it is being jammed and alerts the control room.
• VHF radio backup: radio-frequency recovery, such as Tracker’s network, keeps working when GPS and GSM are blocked.
• Early-warning alerts for unexpected movement or power disconnection.

Protect yourself

• After locking your car, check the doors are actually locked.
• Choose a tracker with jamming detection or radio backup if your car is high risk.
