There are many factors to consider when you are shopping for a home alarm system. The alarm type is probably on top of most homeowners’ list. However, deciding on what type of sensors to install is also very important because they are the most vital component of your home alarm system. An efficient alarm system sensor will detect any intrusions and save you from unfortunate circumstances.
Many of us are familiar with motion sensors, as they have become a common part of most home security systems. These sensors are much like the motion detectors that open the doors to the grocery store or cause the sinks and toilets in the airport to activate without touch. We see motion-sensing devices everywhere. But how do they work?
There are two basic types of motion detecting systems. There are those with active sensors and those with passive sensors. Active sensors send out ultrasonic sound waves and passive sensors detect infrared energy.
