Knowledge Quiz: Motion Detector Guide
Open Quiz
5 quick questions - see how much you learned!
1) What does a PIR motion detector primarily detect?
Answer: C
PIR = Passive Infrared. It detects motion by sensing changes in heat patterns, typically from warm bodies moving across its view.
2) Why do dual-technology motion detectors reduce false alarms?
Answer: B
Dual-tech sensors require two different sensing methods to agree, which filters out common triggers like heat blasts, curtains, or small animals.
3) What’s the most common cause of motion detector false alarms in homes?
Answer: A
PIR sensors react to heat changes. HVAC vents, radiators, fireplaces, and sunlight patches are classic false-alarm triggers.
4) Where is a “best practice” placement for a standard indoor motion detector?
Answer: D
Corner placement at ~7–8 feet is the sweet spot: wide coverage, fewer dead zones, and better pet immunity performance.
5) If you have large dogs and past false alarms, what’s usually the best upgrade?
Answer: C
Dual-tech and advanced pet-immune sensors are designed to reduce pet triggers and environmental false alarms while keeping strong intrusion detection.
