Chances are you already know that the main purpose of a motion sensor is to spot movement in a specified space. But you may still be wondering: How do they work? What kind of technology is involved, and should you use them? This simple explanation will respond to your questions and provide reasons why these implements are such an important aspect of your home’s security.
Why Are Asheville Motion Sensors Used?
You can generally expect a residential motion detector to provide coverage for a zone within a distance of six to 70 feet. If required, you can find models that can increase the scope of your coverage even more. These tools are generally used in things like exterior flood lights. Whenever they notice a disturbance, they prompt your lighting and illuminate your home’s perimeter.
Along with lights, you’ll also find motion sensors used in surveillance systems like the ADT outdoor security camera. This powerful component can be programmed to send alerts and even video segments to your mobile device when activity is found.
Active Motion Sensors
Active sensors, as the name suggests, continually emit a signal or wave and then measure the rate of return. When there is a fluctuation in the reply, movement is shown and your command center is alerted. Microwave sensors are the most common kind of active device. You will even find ultrasonic sensors that utilize sound waves and reflective sensors that track the bounce-back rate of infrared light.
Passive Infrared Motion Sensors
Another one of the most prevalent kinds of motion detectors in Asheville is the passive infrared (PIR) motion sensor. Different from active devices, they don’t constantly send out a signal. Instead, they will detect temperature changes within a designated zone. A sudden heat increase, like a person walking into a room, will trip the passive sensor.
If comparing to active sensors, PIR options require not as much power, are more straightforward to implement, and are more cost-effective. As an added advantage, you are able to adjust the sensitivity levels in most cases. For instance, the flexible ADP motion sensor can be programmed to disregard furry friends less than 60 pounds.
Additional Kinds Of Motion Sensors
You should know that there are more than active and passive detectors. You’ll even discover some kinds that employ two or more sensing mechanisms. Known as combined, dual, or hybrid sensors, these components assist in minimizing false alarms as both kinds of sensors need to be tripped for your alarm to activate. You might even see vibration detectors and tomographic motion sensors that are typically found in larger commercial areas.
