Motion Detecting Sensors 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.
Added:

Do Motion Sensors Work in the Dark?
Passive infrared motion sensors work by detecting changes in infrared energy. This allows them to work in the dark, Learn more about motion detection sensors and how they work.

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.

Can I Use Motions with a Qolsys IQ Panel 2?
Any wireless motion sensor will work with the IQ Panel 2, as long as it operates at a wireless frequency that is compatible with the system's daughterboard. The standard daughterboard accepts the 319.5 MHz frequency, but there are also others. Find out which motions work with the IQ Panel 2.

How Do I Add an IQ Motion to a Qolsys IQ Panel 2?
An IQ Motion can be added to a Qolsys IQ Panel 2 by putting the system into its auto-learn mode for enrolling new sensors and then activating the IQ Motion. The sensor will then be added to the system, and its settings can be configured. Find out how to add an IQ Motion to a Qolsys IQ Panel 2.

Where Should I Install My Motion Detector?
There are several things you should keep in mind when choosing a location for a motion detector. The ideal location for a motion detector is in the corner of a room and away from any windows. The device should be placed 6 to 8 feet off the ground. Learn more about where to install a motion sensor.

How Do I Set Up a Pet Alley Lens On a PIR Motion?
Installing a pet alley lens on a PIR motion is very easy. First remove the front cover and the support frame. Then take out the old lens and install the pet alley lens. Make sure the new lens is properly aligned. Finally, reapply the frame and cover. Learn more about replacing a PIR motion lens.
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.

Microwave vs. Passive Infrared Motion Detectors
Two of the most common methods for detecting motion are microwave sensing and passive infrared technology. These two methods are both highly effective in detecting motion, but they operate in completely different manners. Learn more about microwave vs. passive infrared motion detection.
