Want To Know How Motion Sensors Work?

At the end of the day, every motion detector will trigger when it detects unusual movement. However, the question still remains: How do they work? What kind of technology do they use, and should you use them? This basic explanation will answer your questions and give you clarity on why these implements are such an indispensable part of your home’s defense.

Why Are Motion Sensors Implemented?

You can generally expect a home security motion detector to monitor a space somewhere inside a distance of six to 70 feet. If needed, you may find options that can extend your coverage to a greater degree. These tools are often found in features like outdoor flood lights. Whenever they observe unusual activity, they prompt your lights which shine down on your home’s perimeter.

In addition to lighting, you’ll also discover motion sensors in video cameras like the ADT outdoor security camera. This versatile device is able to be customized to send alerts and even video clips to your mobile device when motion is detected.

Active Motion Sensors

Active sensors, as you can probably guess, actively emit a type of wave or signal and then record the response time. When there is a fluctuation in the rate of response, movement is indicated and your command center is notified. Microwave sensors are the most prevalent form of active device. You will even find ultrasonic sensors that employ sound waves and area reflective sensors that track the response rates of infrared light.

Passive Infrared Motion Sensors

Another one of the most prevalent sorts of motion detectors is the passive infrared --or PIR-- motion sensor. Different from active devices, they won’t constantly send out a signal. Instead, they will detect changes in temperature inside a specified area. An abrupt heat increase, like an individual walking through a room, will trigger the sensor.

If comparing to active types, PIR options need a lower amount of power, are more straightforward to run, and cost less. As an additional benefit, you can alter the degree of sensitivity for most installations. For example, the flexible ADP motion sensor may be customized to dismiss four-legged occupants under 60 pounds.

Additional Types Of Motion Sensors

You will come across various motion sensors that employ more than one type of technology. Usually identified as dual, combined, or hybrid sensors, these devices assist in minimizing false alarms as both types of sensors need to be triggered for your alarm to activate. You will also encounter vibration sensors and tomographic motion devices that are typically found in larger commercial buildings.
