Motion detector

« Back to Glossary Index

A motion detector is a device used in the burglar alarm industry to detect movement within a specific area. It is a crucial component of any security system as it can detect intruders and alert the monitoring center or the homeowner. The motion detector works by sensing changes in infrared radiation, which is emitted by all living beings. When an intruder enters the area, the motion detector senses the change in infrared radiation and triggers the alarm.

There are different types of motion detectors available in the market, including passive infrared (PIR) detectors, microwave detectors, and dual technology detectors. PIR detectors are the most common type and work by detecting changes in temperature within the area. Microwave detectors, on the other hand, emit microwave signals and detect changes in the frequency of the reflected signal. Dual technology detectors combine both PIR and microwave technology to reduce false alarms.

1. How do motion detectors work in burglar alarms?

Motion detectors in burglar alarms work by detecting movement within a designated area. They use infrared technology to sense changes in heat and movement, and when triggered, they send a signal to the alarm system to activate an alarm or alert the monitoring center.

2. What types of motion detectors are available for burglar alarms?

There are several types of motion detectors available for burglar alarms, including passive infrared (PIR) detectors, microwave detectors, and dual technology detectors that combine both PIR and microwave technology. Some motion detectors also have pet immunity features to prevent false alarms caused by pets.

3. Where should motion detectors be placed in a home or business?

Motion detectors should be placed in areas where intruders are likely to enter, such as near doors and windows. They should also be placed in areas where valuable items are stored, such as safes or jewelry boxes. It’s important to avoid placing motion detectors near sources of heat or air conditioning, as this can cause false alarms.
