Intruder Alarm Dual Tech Detectors

Looking much the same as PIR detectors, though usually slightly bigger in size, dual tech detectors use microwave technology to detect movement.

Dual techs would typically be installed in places where there is a more harsh enviroment. ie a warehouse or garage where there could be a lot of drafts and changes to the tempature.

Dual tech detectors also come as pet friendly detectors, 360 degree detectors, anti-masking detectors and long range detectors.
