Active and Passive Sensors
An active motion detector sends out a signal that is disrupted by movement. This means that when someone crosses the signal's path, the sensor is triggered, and it sets off an alarm. Passive motion detectors use infrared (PIR) sensors. These sensors are sensitive to infrared radiation and can detect body heat and changes in temperature.
Sensors Are Triggered
When the sensors are triggered, what happens next really depends on the kind of setup you have. If the motion detectors are a part of a professionally monitored security system, then the monitoring center will notice the alarm and send the authorities even if they can't reach you.
If the motion detectors have a smart sensor that is separate from your home security system, you will get a notification on your mobile device. Then it is up to you to decide what happens next. If you aren't home, you can either call the police or have a trusted neighbor check things out for you.
Finally, if you have one of the more basic motion detectors and sensors, then it probably has a built-in siren and you have to be at home to hear it. You will not receive any notifications, and the sensor is not monitored.
Motion Detector Placement
In order for the motion detectors to do their job, they need to be properly installed and placed. When they are not properly installed, you may find a high risk of false alarms, if they even work well at all.
If you are using PIR motion sensors in Fort Worth, they need to be kept away from any kind of heat source or you can have several false alarms. All sensors also should be installed near entryways and around walking paths where people will be passing by, and the sensors should be placed higher up so that pets and other animals can't accidentally set them off.
Motion Detectors and Security Systems
Motion detectors and sensors are always going to work better when they are paired with a high-quality home security system that is being professionally monitored. If the alarm is triggered, you will find that with these systems, you will have much faster response times, and you can begin to eliminate the possibility of false alarms.
