Frequently Asked Questions (FAQs)

1. Are sensor lights good for security?

If you want to improve nighttime security around your home, motion sensor lights are both effective and affordable.

2. How does automatic light sensor work?

Motion detectors are small electronic eyes that detect infrared waves, i.e. heat waves that radiate from moving objects. When the detector senses an object moving across its field of view — especially warmer objects such as people, animals and cars — it electronically turns on the lights.

3. Which sensor is best for motion detection?

PIR's are the most commonly utilized type of sensor in motion detectors and security systems, as they are some of the most reliable when it comes to detecting motion in the room or area where they are placed.

4. Can a flashlight set off a motion detector?

Here's what I found. Lights can trigger a Motion Sensor. For Motion Sensors which sense Infrared Radiation, lights which quickly change in temperature can cause the sensor to trigger. Motion sensors which use image comparison can also be set off by light when a sudden change in light intensity occurs rapidly.
