WiPro III does without motion detectors, as used in conventional car alarm systems, and instead uses safety-encoded wireless magnetic contacts to monitor vehicle doors, windows and flaps. In addition to low installation costs, this also has the advantage that people and pets can move freely in the vehicle when the alarm system is activated, without having to switch off certain sensors. It is also possible to connect the vehicle's own door contacts or the CAN bus system. The "easy add" function makes the subsequent coupling of new radio accessories easy.
