Motion sensors or motion detectors or Passive Infra-red (PIR) sensors have been a staple in the home security industry for decades. A key part of most home security equipment designs. Most homes with home security systems installed use motion sensors. How did motion detectors also known as motion sensors become the go-to sensor for home security users? The answer lies in its functionality.
First, let me state that motion detectors haven’t always been the most reliable or efficient sensors over the years, the motion detectors you see today have come a long way. When you think of older home security systems, the ones with the huge control panels and wires and more wires running from a cluster in the closet or your attic connected to the numerous points of entry throughout the house. Those systems were very complicated, lots of hardware and wires and maintenance, older motion detectors where the reason behind a lot of maintenance calls to the home security company, they were also the cause of numerous false alarms over the years. Some home security users had so many false alarms they stopped using their home security system altogether, to avoid the hassle and false alarm fees.
It wasn’t unusual for a motion detector to set off an alarm because of a balloon floating to the ceiling or small animal running around the house. They seemed overly sensitive and impractical. Motion sensors were also a staple for businesses and commercial locations looking to cover wide areas with a security system after hours. If you’ve ever been in a warehouse you might of seen a dozen motion sensors strategically positioned in high traffic areas, motion sensors and nothing more than the locks on the doors.
Motion sensors have come a long way, they are now typically pet friendly- depending on the size of the pet typically around 40lbs. The sensitivity issues have been addressed too, the Passive Infra-Red (PIR) is capable of picking up a person or animal in its path, based on temperature or body heat. These triggers set off the motion sensors as opposed to just anything moving in its path. These improvements have also made home security systems a lot more appealing to people. Home security systems are now viewed as more reliable than they ever before, thanks to the improvements in motion sensors.
Motion detectors are a great sensor for people who may be concerned about break-ins mainly when they are away, and the property is supposed to be empty. Remember most motion detectors are typically turned off when people are in the house going about their day, they can be used at night when there’s minimal movement around the property. It’s important to understand how you want to use a home security system before picking out any sensors. Motion sensors have withstood the test of time and will continue to provide home security users with the peace of mind they deserve.
