You’ve probably got a reasonable understanding of what motion detectors do merely based on their name. Indeed, they sense activity, but how precisely do they work? Take a moment to learn about the technology behind them and the different sorts of devices you might come across. You’ll achieve a clearer appreciation of how they work and how you are able to integrate them into your contemporary smart home.


What is the technology that drives motion detectors?

Identifying movement can be performed in a few specific ways, but motion detectors are generally grouped into either of these two categories - active or passive.

● Active motion detectors: These devices are deemed active, as they regularly broadcast transmissions like microwaves and then assess the time of response. Motion is indicated when the return time changes. While microwave sensors are most often found, you’ll also encounter active motion detectors that use infrared light or sound waves.

● Passive infrared (PIR) motion detectors: Usually encountered within home security installations, PIR motion detectors perform by discovering variations in the ambient temperature. ​​In essence, the component detects what the standard temperature is supposed to be within a given area. If there are instant heat spikes, like an invader skulking along the room, the sensor takes notice and sets off your alarm. Since they aren’t continuously transmitting signals, passive detectors usually consume less power and are more economical to operate.

Besides active and passive, you may discover hybrid motion sensors that utilize a mix of technologies. These can help lower false alarms, as every sensor has to be triggered before the alarm is prompted. Other possibilities include vibration motion detectors and tomographic devices that are often used in bigger industrial spaces.

How to use Scottsdale motion detectors

The chief objective of motion detectors is to detect activity within a given area, generally up to 50 feet away. You’ll commonly find them integrated into outdoor floodlights or as standalone devices within the interior of your property. When motion is noticed, they’ll activate your alarm and inform your professional monitoring agents.

But contemporary motion detectors are more versatile than ever before. In fact, they are able to interact directly with other smart devices. For instance, if movement is noticed, they can trigger your lights to switch on or your surveillance camera to start recording. They can even notify your smart thermostat to modify the temperature.

Get immediate notifications and adjust settings for animals

Another significant advantage of current motion detectors is that you’ll get immediate updates transmitted to your smartphone whenever the sensor is tripped. If you own house pets, you are even able to help preempt false alarms by customizing settings to account for the size of your four-legged family members.
