Passive Infrared Motion Detecting Sensors Frequently Asked Questions

Why Do Insects and Small Animals Set Off PIR Motion Detectors?
Motion detectors respond to infrared (IR) energy. Since insects and rodents emit IR energy, they can activate motion sensors if they get close enough. Learn about motion sensors.
Added:

Dual Tech Motion vs. Traditional Motion
There are two main types of motions. There are dual-tech motions that use both PIR and microwave, and there are traditional motions that only use PIR. Learn about motion sensors.
Added:

What is a Walk Test?
You should perform a Walk Test after installing a new motion sensor to make sure it responds properly and won't cause false alarms. Learn about Walk Tests and how they work.
Added:

What is a PIR Motion Sensor?
Passive infrared (PIR) technology is the most common method for detecting motion. This involves looking for changes in infrared energy. Learn about PIR motion sensors.
Added:

Do Cats Set Off Motion Detectors?
Animals can activate motions if they are able to get in their direct field of view. This is usually the result of a poor installation. Learn more about pet-immune 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.
Added:

Does a Honeywell 5800PIR-RES Motion Light Up?
A Honeywell 5800PIR-RES Motion will light up when it is in its walk test mode. The sensor will automatically activate this mode whenever it is first powered on. In this mode, the sensor will display a red LED light upon detecting. Learn more about walk test mode on a Honeywell 5800IR-RES.
Added:

What Is the Range of My PIR Motion?
Every passive infrared (PIR) motion has its own range and field of vision. The range for one PIR motion can be considerably different from that of another. It is very important that you use a PIR motion with an appropriate range for the situation. Find out the range of your PIR motion.
Added:

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.
