How Motion Sensors REALLY Work (PIR vs. Microwave)

Описание: You see them in every office and home, but do you know how that little plastic box actually spots an intruder? 🕵️‍♂️🚨

In this video, we "demystify" the technology inside security sensors. We reveal how Passive Infrared (PIR) sensors use "heat vision" to detect body heat, and how Microwave sensors use radar to see through walls. We also explain why combining them into a Dual-Tech sensor is the ultimate "False Alarm Killer."

Plus, we tackle the classic problems: How to protect glass windows without false alarms, and the low-tech trick sensors use to let your dog roam free (and why it might fail!).
