let's talk about the technology. Most systems installed today are wireless. Now don't get confused like some providers would like you to be. A security and lifestyle monitoring system consists of three very important segments.The first segment is detection. Detection is the part of the system that detects status changes or emergencies (your door was opened by an unauthorized party or your front window was broken, for example). Detection components include door and window contacts, Passive Infrared (PIR) motion detectors, glass break sensors, smoke detectors, carbon monoxide detectors and more.The second element of a system is annunciation. In a nutshell, annunciation announces that a system has been breached or needs attention at the source: sirens, bells or flashing lights are all examples of annunciation. It’s important to note that audible or visual annunciation occurs only at the source of the potential security breach; in your home or business for example. The part of the system that alerts people who are currently away from your home’s perimeter is defined as monitoring or communication.Which brings us to the third, and probably the most important, element of any system. Your monitoring system is the element that communicates emergencies and system health and maintenance information to a central station monitoring center. It also broadcasts alerts to anyone who is directly associated with the premises. For example, if you get a text alert saying that your patio door lock was disabled, that’s a prime example of monitoring and communication. This is the segment of your system that serves as the umbilical cord, connecting you and the outside world. In most cases, your monitoring and communication system is the element that minimizes (or even eliminates) the possibility of a disaster.
