Honeywell DT8035 Frequently Asked Questions

Do Alarm Motion Sensors Work Through Glass?
Motion sensors detect changes in infrared (IR) energy. This cannot be done through modern glass, so motion sensors do not sense through glass. Learn more about PIR motion sensors.
Added:

Do Motion Detectors Work Through Windows?
Motion sensors are usually unable to detect motion through glass. The infrared energy needed to activate a motion won't easily pass through glass. Learn more about motion sensors.

How Does a Pet-Immune Motion Detector Work?
If a motion detector is pet-immune, it can be set up in a way that it will not activate because of a small animal walking by. Find out more about pet-immune motion detectors.
Added:

What Makes a Motion "Dual Tech"?
A "Dual Tech" motion sensor uses both passive infrared (PIR) technology and microwave technology to detect motion. Both the PIR and microwave sensors must activate in order for the device to trigger. This makes them great for reducing false alarms. Learn more about Dual Tech motion sensors.
Added:

What is a Microwave Motion Detector?
A motion that uses microwave technology will send out microwave signals to determine the structures in a room. The signals will bounce off the structures and return to the sensor with precise timing. A change in this timing means that motion is present. Learn more about microwave sensors.

Honeywell IS-3035 vs DT8035 Motion Detector?
The difference between the IS-3035 motion and the DT-8035 motion is that the DT-8035 uses PIR and microwave to detect motion. Learn about the two devices.
