You’ve probably got a reasonable grasp of what motion detectors do simply based on their name. Indeed, they detect activity, but how precisely do they work? Take a moment to learn about the technology that powers them and the various types of sensors you might encounter. You’ll gain a clearer understanding of how they work and how you may integrate them into your modern smart home.


What is the technology that drives motion detectors?

Detecting movement can be done in a number of specific ways, but motion detectors are typically classified into either of these categories - active or passive.

● Active motion detectors: These sensors are viewed as active, as they constantly send out signals like microwaves and then assess the time of response. Activity is signified when the response time changes. Although microwave sensors are most prevalent, you’ll also discover active motion detectors that use sound waves or infrared light.

● Passive infrared (PIR) motion detectors: Often seen within home security installations, PIR motion detectors function by discovering shifts in the surrounding temperature. ​​In essence, the component detects what the normal temperature is expected to be within a given area. If there are rapid spikes of heat, like an intruder creeping across the space, the sensor recognizes it and triggers your security alarm. Since they aren’t actively transmitting signals, passive detectors typically consume less power and are more cost-effective to operate.

In addition to active and passive, you may discover hybrid motion detectors that employ multiple technologies. These can help lower false alarms, as each sensor has to be activated before the warning siren is prompted. Additional possibilities include vibration motion detectors and tomographic devices that are typically employed in bigger industrial facilities.

Ways to implement St. Petersburg motion detectors

The main purpose of motion detectors is to spot motion within a designated area, typically up to 50 feet away. You’ll usually find them included in outdoor floodlights or as standalone devices inside your home. When motion is noticed, they’ll set off your alarm system and advise your professional monitoring agents.

But contemporary motion detectors are more functional than at any time before. As a matter of fact, they are able to interact directly with other smart components. To illustrate, they can trigger your connected smart lights to turn on or your video camera to record if movement is detected. They may even signal your smart thermostat to change the temperature.

Get instant updates and adjust settings for pets

One more great advantage of current motion detectors is that you’ll get immediate updates transmitted to your smartphone each time the device is set off. If you own animals, you are even able to help ward off false alarms by customizing settings to accommodate the size of your four-legged companions.
