You understand the fundamental objective of motion sensors is to set off your alarm when activity is recognized. However, the question still remains: How do they work? What kind of technology is involved, and are they necessary? This basic explanation will respond to your questions and provide reasons why these components are such an indispensable facet of your home security system.
Why Are San Antonio Motion Sensors Implemented?
You can generally expect a residential motion detector to provide coverage for an area somewhere within a distance of six to 70 feet. If required, you may locate models that will increase your coverage even more. These components are often incorporated into features like exterior flood lights. When they observe movement, they trigger your lighting and brighten your surroundings.
In addition to lights, you’ll also see motion sensors in video cameras like the ADT outdoor security camera. This versatile component may be set to deliver updates and even video segments to your mobile device when activity is found.
Active Motion Sensors
Active sensors, as you might expect, continuously emit a type of wave or signal and then analyze the response time. When 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 can also come across ultrasonic sensors that use sound waves and area reflective sensors that measure the bounce-back rate of infrared light.
Passive Infrared Motion Sensors
One of the other most ubiquitous types of motion detectors in San Antonio is the passive infrared (PIR) motion sensor. Unlike active models, they won’t constantly emit a signal. Instead, they will discern temperature changes within a specified space. A sudden heat increase, like someone sneaking through a room, will trigger the passive sensor.
When compared to active types, PIR components use not as much power, are easier to run, and cost less. As an added benefit, you can change the sensitivity levels in most cases. For instance, the pet-friendly ADP motion sensor may be customized to disregard tail-wagging family members less than 60 pounds.
A Few Extra Types Of Motion Sensors
You may discover various motion sensors that employ more than one type of functionality. Known as dual, combined, or hybrid sensors, these options assist in minimizing false alarms as both styles of sensors need to be set off for your alarm to activate. You will also come across vibration detectors and tomographic motion sensors that are generally found in more expansive commercial areas.
