Homeowners looking for peace of mind can upgrade their security system with a motion detector. A built-in motion detector within a home security system will automatically alert of an intruder by switching on a light when movement is detected. The motion detector light will continue to stay on as long as it senses movement. Once all is clear, the light will turn off automatically after a set time.

Types of motion detectors

Motion Detectors

There are countless motion detectors on the market. The most common are:

Combination devices also exist, which incorporate more than one of these technologies so that false alarm instances are reduced.

How do motion detectors protect the home?

A motion detecting device can be integrated into an existing home security system. They can be fitted outside to keep intruders away from the house, but in this case you may end up with many false alarms as animals and guests can trigger them.

These devices are most often placed inside homes, facing towards an entryway or having a field of vision that covers one or more rooms. Anything that moves within this field will trigger the alarm or another function that the unit can perform.

Choose the best device for different situations: Avoid false alarms

Which motion detector you choose will depend on what you need it for. Those that handle lights can be used outside the house for safety purposes. They can also be used to provide lighting when needed and conserve power when not. In some neighborhoods, a motion detection device that triggers a light is often enough to alert the neighbors to potential intruders.

Nonetheless, light-activating devices can turn up a lot of false positives, especially if used outside. Cats and dogs can trigger them, as can some other curious animals such as deer or raccoons. In this case, a pet-sensitive motion detector is preferred that will provide a "sensing buffer" for animals up to 40 or 80 pounds, depending on the system.

Or, it might be better to consider a motion detecting device that raises alarms or calls a security company inside your house. The best place to put them is facing a doorway where they can get a large field of vision that covers the whole room or at a central part of the house where intruders must cross if they are already inside.

False motion alarms are a major concern for homeowners, and rightly so. If you don't want to deal with complaints from neighbors or waking at all hours because of a false positive trigger, it's critical to shop carefully for a motion detector based on features. A pet-friendly sensor can avert triggers from small animals, static, and other ambient factors. You can also consider a motion sensor with an adjustable distance range or sensitivity to prevent unnecessary alarm trips in the middle of the night.
