You’re likely to have a fairly decent idea of what motion detectors do simply based on their name. Of course, they detect motion, but how specifically do they work? Take a minute to learn about the technology that powers them and the various sorts of sensors you might encounter. You’ll get a better comprehension of how they work and how you are able to blend them into your contemporary smart home.


What is the technology that drives motion detectors?

Detecting motion can be done in several specific ways, but motion detectors are usually grouped into either of these categories - active or passive.

● Active motion detectors: These devices are viewed as active, as they continually broadcast transmissions like microwaves and then assess the response time. Movement is indicated when the time of response changes. While microwave sensors are most common, you’ll also find active motion detectors that use sound waves or infrared light.

● Passive infrared (PIR) motion detectors: Frequently encountered within home security applications, PIR motion detectors function by discovering variations in the surrounding temperature. ​​Basically, the component notes what the standard temperature is supposed to be within a specified area. If there are instant heat spikes, like a burglar sneaking along the room, the sensor takes notice and sets off your warning. Since they don’t constantly emit signals, passive detectors usually need less power and are more economical to operate.

Besides passive and active, you could come across hybrid motion detectors that utilize multiple technologies. These can help minimize false alarms, as each sensor must be tripped before the warning siren goes off. Other options include vibration motion detectors and tomographic sensors that are typically employed in larger commercial or industrial locations.

Ways to use Evansville motion detectors

The primary purpose of motion detectors is to identify motion within a designated area, usually up to 50 feet away. You’ll commonly find them incorporated into outside floodlights or as independent devices within the interior of your residence. When activity is sensed, they’ll initiate your alarm and inform your dedicated monitoring team.

But modern motion detectors are more versatile than they’ve been in the past. In fact, they are able to communicate directly with other smart devices. For instance, if motion is noticed, they might trigger your lighting to activate or your video camera to commence recording. They may even signal your smart thermostat to change the temperature.

Receive instant updates and adjust settings for furry friends

One more significant benefit of current motion detectors is that you’ll have instant notifications dispatched to your mobile phone any time the device is triggered. If you own animals, you can even ward off false alarms by adjusting settings to accommodate the size of your furry friends.
