Independent microwave motion detectors for lighting are not common because most microwave detectors will include microwave and PIR detection in dual technology settings. When using the dual technology setting, the microwave and PIR sensors must be triggered to sound an alarm. This can be a good way to prevent false positives. Unfortunately, if an intruder can spoof a PIR sensor or microwave radar, the device will not be activated and no alarm will be issued. However, it is extremely difficult to escape these two detection methods, which makes dual technology a reliable security solution for consumers.
