The DEFA DVS90 alarm system is based on electronics that can be adapted to individual needs. This makes installation in most vehicles significantly easier than other alarm systems using 12 V or 24 V battery voltage. It responds to tampering attempts, breakage of glass and level changes (theft of tyres) and is able to distinguish between dangerous and harmless movements inside the vehicle. So there won’t be any false alarms by flies and the likes. It is also suitable for all types of CAN bus in today’s vehicles.
