What is an advantage of having a dual technology sensor?

A dual technology sensor combines two different detection methods—typically passive infrared (PIR) and microwave detection. This combination enhances the sensor's capability to accurately identify actual intrusions while minimizing the likelihood of false alarms.

When both technologies are used together, the sensor is designed to trigger an alarm only when both detection methods are activated. For example, the PIR might detect body heat, while the microwave component detects movement. If only one of these sensors is triggered—such as by a pet moving through the area—the dual technology sensor may not activate, effectively reducing the chances of false alarms caused by non-threatening stimuli like insects or moving objects.

This feature is particularly valuable in environments prone to false activations, enabling more reliable security without the constant interruptions caused by false alarms, which can be costly and lead to complacency in response measures.
