It’s probably safe to say you already know that the main objective of a motion sensor is to identify any action within a specified area. But you may still be wondering: How do they work? What kind of technology is involved, and are they necessary? This basic explanation will answer your questions and give you an idea of why these components are such an indispensable part of your home security system.
Why Are Seattle Motion Sensors Implemented?
Typical home security motion sensors will detect activity in the nearby surroundings up to 70 feet away. If required, you may find options that can increase the scope of your coverage to a greater extent. These tools are generally found in features like exterior flood lights. Whenever they detect movement, they prompt your lighting which shine down on your home’s perimeter.
As well as flood lights, you’ll also find motion sensors used in surveillance systems like the ADT outdoor security camera. This versatile camera can be customized to deliver alerts and even video segments to your cell phone when motion is sensed.
Active Motion Sensors
Active sensors, as you can probably guess, continuously discharge a type of wave or signal and then measure the rate of return. Whenever there is a change in the response time, motion is signified and your command center is notified. Microwave sensors are the most widespread kind of active device. You will even find ultrasonic sensors that use sound waves and reflective sensors that assess the response rates of infrared light.
Passive Infrared Motion Sensors
Another one of the most common kinds of motion detection devices in Seattle is the passive infrared (PIR) motion sensor. Dissimilar to active devices, they won’t continuously send out a signal. Conversely, they are able to notice changes in temperature inside a specified space. An abrupt heat increase, like a person moving into a room, will trip the passive sensor.
If comparing to active types, PIR options require less power, are easier to operate, and are more cost-effective. As an extra advantage, you may alter the degree of sensitivity for most installations. To illustrate, the flexible ADP motion sensor may be set to ignore furry friends weighing under 60 pounds.
A Few Extra Kinds Of Motion Sensors
You should also understand that there are more than passive and active detectors. In fact, there are some types that utilize two or more methods of sensing. Known as hybrid, dual technology, or combined sensors, these options help cut down on false alarms as both types of sensors have to be set off for your alarm to turn on. You might even see vibration detection equipment and tomographic motion detectors that are generally utilized in bigger commercial spaces.
