In all likelihood you already know that the primary purpose of a motion sensor is to identify any action within a specified area. But how do they work? What kind of technology is involved, and are they necessary? This simple guide will respond to your questions and give you an idea of why these devices are such a vital part of your home security system.
Why Are Dothan Motion Sensors Implemented?
Standard in-home motion sensors will detect movement in a set distance from its position up to 70 feet away. If needed, you may locate options that can extend your coverage to a greater degree. These components are often incorporated into other elements like outdoor flood lights. When they detect a disturbance, they trigger your lighting and illuminate your home’s perimeter.
In addition to lights, you’ll also discover motion sensors in video cameras like the ADT outdoor security camera. This adaptable component can be set to dispatch alerts and even a video clip to your smartphone when movement is detected.
Active Motion Sensors
Active sensors, as the name suggests, continually send out a signal or wave and then record the rate of return. If there is a fluctuation in the response time, activity is indicated and your alarm system is notified. Microwave sensors are the most common kind of active device. You will even run into ultrasonic sensors that employ sound waves and reflective sensors that measure the bounce-back rate of infrared light.
Passive Infrared Motion Sensors
Another one of the most ubiquitous types of motion detectors in Dothan is the passive infrared (PIR) motion sensor. Unlike active devices, they don’t continuously discharge a signal. Instead, they can discern temperature changes inside a designated zone. A rapid change in heat, like a person walking through a room, will set off the passive sensor.
If comparing to active types, PIR devices require a lower amount of power, are more straightforward to implement, and are less expensive. As an added benefit, you can alter the levels of sensitivity in most cases. For example, the animal-friendly ADP motion sensor may be programmed to dismiss furry family members weighing under 60 pounds.
A Few Extra Types Of Motion Sensors
You may find motion sensors that use two kinds of functionality. Usually identified as hybrid, dual technology, or combined sensors, these components help cut down on false alarms as both kinds of sensors have to be set off for your alarm to engage. You will also see vibration detection equipment and tomographic motion devices that are typically found in larger commercial buildings.
Find A Security Package With Motion Sensors in Dothan
Knowing that you have a little more knowledge of how motion sensors work in Dothan, it’s a great time to request your own security system with these important components. When you get them as a core feature of a package, you’ll enjoy peace of mind knowing they will be implemented skillfully with your other security tools.
