How Do Motion Sensors Work In Ann Arbor?

You understand the basic purpose of motion sensors is to set off your alarm when activity is observed. But how do they work? What is the technology behind them, and should you use them? This straightforward tutorial will respond to your questions and provide reasons why these devices are such a vital facet of your home’s defense.

How Are Ann Arbor Motion Sensors Implemented?

Standard home security motion sensors will look for disturbances within a set distance between six to 70 feet. If you want, you can find models that can extend your coverage to a greater extent. These devices are commonly used in things like exterior flood lights. Whenever they notice unusual activity, they signal your lights and illuminate your surroundings.

In addition to lighting, you’ll also see motion sensors in surveillance systems like the ADT outdoor security camera. This powerful component is able to be programmed to dispatch updates and even a video clip to your cell phone when motion is found.

Active Motion Sensors

Active sensors, as you might expect, continually emit some kind of signal and then measure the rate of return. If there is a fluctuation in the rate of response, movement is signified and your security system is warned. 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 track the bounce-back rate of infrared light.

Passive Infrared Motion Sensors

One of the other most prevalent kinds of motion detection devices in Ann Arbor is the passive infrared --or PIR-- motion sensor. Dissimilar to active models, they don’t continually emit a signal. Instead, they are able to discern changes in temperature within a designated area. An abrupt heat increase, like an individual walking across a room, will set off the sensor.

In comparison to active kinds, PIR components require less power, are simpler to operate, and cost less. As an added benefit, you may adjust the levels of sensitivity for most installations. For example, the pet-friendly ADP motion sensor can be set to disregard tail-wagging friends less than 60 pounds.

Additional Sorts Of Motion Sensors

You may come across some motion sensors that employ two types of technology. Known as dual, combined, or hybrid sensors, these components assist in minimizing false alarms as both types of sensors must be tripped for your alarm to activate. You will also encounter vibration sensors and tomographic motion devices that are typically employed in more expansive commercial spaces.
