Chances are you already know that the primary purpose of a motion sensor is to detect movement in a specified area. But you may still be wondering: How do they work? What kind of technology do they use, and do you really need them? This simple guide will address your questions and give you clarity on why these components are such an important aspect of your home security system.
How Are Huntsville Motion Sensors Used?
You can generally look for a residential motion detector to cover a space inside a distance of six to 70 feet. If required, you may find models that will increase the scope of your coverage to a greater extent. These tools are often used in things like outside flood lights. When they detect movement, they prompt your lighting and brighten your home’s perimeter.
As well as lights, you’ll also find motion sensors used in surveillance systems like the ADT outdoor security camera. This powerful component may be set to send alerts and even a video clip to your cell phone when motion is found.
Active Motion Sensors
Active sensors, as you can probably guess, continuously discharge some kind of signal and then record the rate of return. Whenever there is a sudden alteration in the response time, movement is indicated and your command center is alerted. Microwave sensors are the most prevalent form of active device. You might also find ultrasonic sensors that use sound waves and area reflective sensors that assess the response time of infrared light.
Passive Infrared Motion Sensors
One of the other most ubiquitous sorts of motion detection devices in Huntsville is the passive infrared (PIR) motion sensor. Different from active devices, they don’t continuously send out a signal. Instead, they will discern changes in temperature inside a designated area. An abrupt heat increase, like a person moving across a room, will set off the passive sensor.
In comparison to active types, PIR components use less power, are simpler to run, and are less expensive. As an extra bonus, you may alter the sensitivity levels in most cases. For instance, the flexible ADP motion sensor is able to be programmed to ignore furry family members under 60 pounds.
Additional Sorts Of Motion Sensors
You will discover various motion sensors that employ more than one type of functionality. Known as dual, combined, or hybrid sensors, these devices aid in reducing false alarms as both styles of sensors have to be set off for your alarm to activate. You could even see vibration detection equipment and tomographic motion devices that are usually found in bigger commercial buildings.
