Every car owner strives to protect his car from intruders as much as possible. The main counteraction to theft today is a car alarm system.
Anti-theft systems perform several main functions:
they warn about penetration into the car interior by sound and light signals;
warn of an attempt of external influence and suspicious approach to the car in the parking lot (removal of wheels, evacuation, impact, etc.);
notify the driver of the penetration and track the further location of the car (if this function is available).
The car alarm system is a whole security system that warns the owner about theft or an attempt to break into the car!
