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.

What Is The Best PIR Motion Sensor?
Passive infrared (PIR) motion sensors come in hardwired and wireless varieties. The best one to use really depends on your needs. Learn all about PIR motion sensors.
Added:

What Is a Motion Sensor?
Most alarm systems will have at least one motion sensor installed. These devices are great for detecting unwanted break-ins. Find out what motion sensors are and how they work.
Added:

What Is a Motion Detector?
Motion sensors represent one of the most commonly used security sensors in homes and businesses. These devices are used to detect movement. Find out what a motion detector is.
Added:

How are Motion Detectors Wired to a Panel?
A hardwired motion detector will normally use a 4-wire connection with the panel. Two wires will transmit data, and the other two transmit power. Learn about motion sensors.
Added:

What Is a Dual Action Motion Sensor?
When a motion sensor uses both PIR and microwave technology, it is often referred to as "dual-action" or "dual-tech". Learn about dual action motion sensors and how they work.
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.

Does a Honeywell VISTA 20P Support Motion Sensors?
A Honeywell VISTA 20P can support hardwired motion sensors. It can also support 345 MHz wireless sensors if a wireless receiver is added. Learn about motion sensors.

What is an Interior Follower Zone?
When a zone is set to interior follower, it will trigger an alarm if the sensor is activated while the system is armed away. Learn more about the interior follower Response Type.
