In all likelihood you already know that the main objective of a motion sensor is to identify activity in a particular zone. But you may still be wondering: How do they work? What kind of technology do they use, and are they necessary? This basic guide will respond to your questions and give you reasons why these implements are such an indispensable part of your home security system.
Why Are Baltimore Motion Sensors Used?
You can generally look for a residential motion detector to monitor an area somewhere within six to 70 feet from its location. If required, you are able to find models that can expand your protection to a greater degree. These tools are often found in features like exterior flood lights. Whenever they observe unusual activity, they trigger your lighting and illuminate your property.
In addition to lights, you’ll also see motion sensors in surveillance systems like the ADT outdoor security camera. This versatile component may be customized to send updates and even a video clip to your smartphone when activity is sensed.
Active Motion Sensors
Active sensors, as you might expect, continually discharge a signal or wave and then analyze the response time. If there is a sudden alteration in the response time, motion is indicated and your security system is notified. Microwave sensors are the most common type of active device. You will even come across ultrasonic sensors that use sound waves and reflective sensors that measure the bounce-back rate of infrared light.
Passive Infrared Motion Sensors
Another one of the most ubiquitous kinds of motion detection devices in Baltimore is the passive infrared (PIR) motion sensor. Unlike active devices, they won’t continually emit a signal. Alternatively, they can discern temperature changes in a specified space. A sudden heat increase, like someone walking across a room, will trip the sensor.
If comparing to active kinds, PIR devices use a lower amount of power, are simpler to operate, and are more cost-effective. As an extra bonus, you can adjust the sensitivity levels for most installations. For instance, the pet-friendly ADP motion sensor may be programmed to disregard four-legged family members weighing under 60 pounds.
A Few Extra Types Of Motion Sensors
You should know that you are able to get more than active and passive detectors. You’ll even discover some types that use two or more sensing technologies. Known as combined, dual, or hybrid sensors, these devices aid in reducing false alarms as both kinds of sensors have to be triggered for your alarm to activate. You could even come across vibration detection equipment and tomographic motion devices that are typically found in more expansive commercial spaces.
