What is the primary purpose of dual technology motion detectors?

The primary purpose of dual technology motion detectors is to reduce false alarms. These devices typically combine two different detection technologies, such as passive infrared (PIR) and microwave sensing. By requiring activation from both sensors to trigger an alarm, dual technology detectors can more effectively differentiate between actual human movement and environmental disturbances, such as pets or changes in temperature.

This dual activation mechanism significantly decreases the likelihood of false alarms, which can be caused by non-threatening factors. As a result, the use of dual technology motion detectors allows security systems to be more reliable and trustworthy, which is crucial for maintaining the confidence of users and minimizing unnecessary responses from law enforcement or security personnel.

While enhancing detection accuracy, improving installation times, and lowering overall costs are beneficial aspects of security technologies, the defining advantage of dual technology motion detectors is their primary focus on reducing false alarms.
