You understand the basic purpose of motion sensors is to trigger your alarm when some form of action is recognized. But you may still be wondering: How do they work? What is the technology behind them, and do you really need them? This straightforward guide will answer your questions and provide clarity on why these devices are such an important part of your home security system.
Why Are Pittsburgh Motion Sensors Implemented?
If you’re wondering about the number of motion sensors you’ll require, you should know that the zone they provide coverage for can fluctuate widely from as little as six feet up to a distance of 70 feet. If needed, you can find models that will extend your coverage to a greater extent. These tools are often used in things like outdoor flood lights. Whenever they detect movement, they signal your lighting which shine down on your home’s perimeter.
Along with flood lights, you’ll also discover motion sensors in surveillance systems like the ADT outdoor security camera. This versatile device can be customized to deliver notifications and even video segments to your smartphone when activity is found.
Active Motion Sensors
Active sensors, as the name suggests, actively emit some kind of signal and then analyze the response time. When there is a fluctuation in the response time, movement is indicated and your security system is notified. Microwave sensors are the most common form of active device. You can even run into ultrasonic sensors that employ sound waves and reflective sensors that track the response time of infrared light.
Passive Infrared Motion Sensors
One of the other most common sorts of motion detection devices in Pittsburgh is the passive infrared (PIR) motion sensor. Dissimilar to active models, they won’t constantly send out a signal. Instead, they are able to notice changes in temperature inside a specified space. A rapid change in heat, like someone walking across a room, will set off the passive sensor.
When compared to active sensors, PIR devices require not as much power, are simpler to run, and cost less. As an extra benefit, you are able to alter the levels of sensitivity for most installations. To illustrate, the flexible ADP motion sensor can be programmed to disregard four-legged friends under 60 pounds.
A Few Extra Kinds Of Motion Sensors
You can find some motion sensors that employ two types of technology. Called hybrid, dual technology, or combined sensors, these devices aid in reducing false alarms as both types of sensors have to be set off for your alarm to activate. You will also see vibration detectors and tomographic motion devices that are usually employed in more expansive commercial spaces.
