How Do Motion Detectors Work In Seattle?

You’re likely to have a pretty good grasp of what motion detectors do simply based on their name. Indeed, they sense motion, but how precisely do they work? Take a little time to learn about the technology behind them and the many sorts of sensors you might come across. You’ll get a clearer appreciation of how they work and how you may integrate them into your advanced smart home.


What is the technology behind motion detectors?

Identifying activity can be achieved in a few different ways, but motion detectors are generally placed into either of these two categories - active or passive.

● Active motion detectors: These sensors are deemed active, as they regularly broadcast signals like microwaves and then assess the time of response. Motion is signified when the response time changes. While microwave sensors are most prevalent, you’ll also find active motion detectors that utilize sound waves or infrared light.

● Passive infrared (PIR) motion detectors: Frequently seen within home security installations, PIR motion detectors operate by recognizing changes in the ambient temperature. ​​In essence, the instrument learns what the regular temperature is expected to be within a given area. If there are sudden heat spikes, like an intruder skulking across the room, the detector recognizes it and initiates your security alarm. Since they aren’t actively sending out signals, passive detectors generally require less power and are less expensive to operate.

In addition to passive and active, you might come across hybrid devices that utilize a mix of technologies. These can help minimize false alarms, as every sensor must be activated before the alarm system is prompted. Additional choices include vibration motion detectors and tomographic devices that are commonly employed in bigger commercial buildings.

Ways to implement Seattle motion detectors

The chief aim of motion detectors is to detect activity within a designated area, usually up to 50 feet away. You’ll regularly find them integrated into exterior floodlights or as standalone devices within your residence. When motion is noticed, they’ll initiate your warning siren and advise your 24/7 monitoring staff.

But present-day motion detectors are more adaptable than ever before. In fact, they are able to connect directly with other smart devices. For example, they can signal your integrated smart light bulbs to switch on or your surveillance device to record whenever movement is detected. They might even alert your smart thermostat to alter the temperature.

Get instant notifications and customize settings for furry friends

One more significant advantage of contemporary motion detectors is that you’ll have instant updates sent to your mobile phone whenever the sensor is set off. If you have house pets, you can even prevent false alarms by adjusting settings to account for the size of your furry companions.
