ITHITRONIK® alarm systems are deliberately designed without motion detectors, since motion detectos are error-prone – no matter whether they are using ultrasound, radar or infrared technology.
This particularly applies to the leisure vehicle segment, where false alarms can be caused by moving curtains, trucks driving by, branches hitting the roof, trapped insects etc.
Furthermore, it is not possible to leave children or animals in the vehicle while the alarm systems is armed. Without these alarms, there is no protection; switching them off after lengthy periods is often complicated and not reproducible.
You shouldn’t have to worry about false alarms or the necessity of disconnecting these alarms. In your leisure time, the focus should be on ease of mind and simple operation.
