You’re likely to have a fairly decent grasp of what motion detectors do merely based on their title. Indeed, they sense motion, but how precisely do they work? Take a little time to learn about the technology that drives them and the different sorts of sensors you might encounter. You’ll gain a better appreciation of how they work and how you can incorporate them into your advanced smart home.


What is the technology behind motion detectors?

Identifying motion can be performed in several different ways, but motion detectors are typically classified into either of these categories - active or passive.

● Active motion detectors: These instruments are considered active, as they continually transmit signals like microwaves and then assess the response time. Movement is shown when the time of response changes. Even though microwave sensors are most prevalent, you’ll also find active motion detectors that utilize infrared light or sound waves.

● Passive infrared (PIR) motion detectors: Commonly encountered within home security installations, PIR motion detectors function by recognizing changes in the surrounding temperature. ​​Essentially, the instrument detects what the usual temperature ought to be within a designated area. If there are abrupt increases of heat, like a burglar creeping along the area, the device observes it and triggers your alarm system. Since they aren’t continuously transmitting signals, passive detectors usually use less power and are more economical to run.

Besides passive and active, you might discover hybrid devices that use more than one technology. These can help reduce false alarms, as each sensor has to be tripped before the alarm sounds. Other choices include vibration motion detectors and tomographic devices that are often employed in more extensive industrial locations.

Ways to implement Alpharetta motion detectors

The primary goal of motion detectors is to identify motion within a specified area, usually up to 50 feet away. You’ll commonly find them included in outside floodlights or as independent devices within your residence. When activity is detected, they’ll set off your alarm system and notify your professional monitoring team.

But contemporary motion detectors are more functional than they’ve been in the past. In fact, they can interact directly with other smart components. For instance, if activity is noticed, they can trigger your lighting to activate or your surveillance camera to commence recording. They might even notify your smart thermostat to change the temperature.

Another tremendous advantage of contemporary motion detectors is that you’ll get alerts delivered to your mobile phone whenever the sensor is triggered. If you have pets, you are even able to help ward off false alarms by tailoring settings to take into account the size of your four-legged family members.
