You know the fundamental objective of motion sensors is to signal 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 explanation will respond to your questions and offer clarity on why these devices are such an indispensable facet of your home’s security.
How Are Motion Sensors Implemented?
Typical home security motion sensors will identify disturbances in a set distance from its position up to 70 feet away. If required, you can find models that will increase the scope of your coverage to a greater extent. These tools are commonly used in other elements like exterior flood lights. When they notice unusual activity, they trigger your lights and illuminate your home’s perimeter.
Along with lighting, you’ll also discover motion sensors in surveillance systems like the ADT outdoor security camera. This adaptable camera can be set to send alerts and even video segments to your cell phone when movement is found.
Active Motion Sensors
Active sensors, as you can probably guess, actively send out a signal or wave and then analyze the speed of the reply. If there is a sudden alteration in the reply, activity is shown and your command center is warned. Microwave sensors are the most prevalent type of active device. You can also come across ultrasonic sensors that utilize sound waves and reflective sensors that measure the bounce-back rate of infrared light.
Passive Infrared Motion Sensors
One of the other most prevalent kinds of motion detection devices in is the passive infrared --or PIR-- motion sensor. Unlike active models, they don’t constantly send out a signal. Instead, they can detect changes in temperature in a designated area. A rapid heat increase, like someone walking across a room, will trip the sensor.
In comparison to active types, PIR options use less power, are easier to run, and are more cost-effective. As an additional advantage, you are able to change the sensitivity levels for most installations. To illustrate, the animal-friendly ADP motion sensor is able to be programmed to disregard four-legged occupants under 60 pounds.
Some Other Types Of Motion Sensors
You may find some motion sensors that use two types of functionality. Known as dual, combined, or hybrid sensors, these options assist in minimizing false alarms as both styles of sensors have to be set off for your alarm to activate. You could even come across vibration detectors and tomographic motion devices that are typically utilized in larger commercial areas.
