What are the differences between a Cat 1 and a Cat 2 car alarm?
Most Insurance Companies will specify that your car should either have a Cat 1 or Cat 2 for the policy to insure against theft. A Category 2 (Cat 2) specifies a car immobiliser and a Category 1 (Cat 1) means a car alarm with incorporated immobiliser. These classification are set by ‘Thatcham’ which is a company that tests car alarms & immobilisers to determine that they reach a certain standard, they then award the systems a Cat 1 or Cat 2 status.
