A Brief on How Intruder Alarm Systems Work

I think we have stated the fact that every space where you live or either work need a complete security solution to safeguard you, your loved ones, your assets, your data and of course your premises from the numerous risks and hazards lurking in every corner.

This is the primary reason why security and video surveillance system’s supply and demand have spiked in the last so many years and the Burglar/ Intruder Alarm Systems have become the most sought after and one of the standard equipment in the home and business security solutions stores and other video surveillance systems outlets. They are becoming quite common and being widely installed in homes, renovation sites, retail shops, offices, banks, gyms, and other commercial businesses. You will get the gist of how wide the spectrum of home and business security solutions have become when you will step into the market to get one for yourself.

The broad spectrum of home, business, and commercial security systems ranges from simple do-it-yourself kits that do not need the assistance of the security system provider to a wide range of high-tech and highly advanced complete house and office security networks that can only be installed with the professional help. But whether it is a DIY security project or the sophisticated technology led ones, all the home alarm systems basically circles around the same design concept which the experts of Sure Secure have deconstructed to help you better understand the working of the Intrusion/ Burglar Alarm Systems.

Operation of an Intruder/Burglar Alarm System

  • To understand the working of an intruder alarm system, one needs to understand the working of an electric circuit.

  • Compare a burglar or an intrusion alarm system and its working to that with the working of an electric circuit or appliance.

  • You need to turn on a switch if you want the lights to light up and start working.

  • This same approach works with the Intruder/Burglar Alarm Systems

  • In an Intruder Alarm System, the movement of an intruder is detected by the switch.

  • When an intruder breaks in through a door or a window, this breach will be detected by the switch which will trigger the burglar alarm system.

Now, the circuits are divided into 2 categories

Open-circuit: When the door or the window will be closed by an intruder, the circuit will be closed and the alarm will be triggered.

Closed-circuit: When the door or the window is closed, the circuit is closed meaning that the electric current can flow from one end to another. Therefore, when the door or window is forcefully opened by an intruder, the circuit will open and the alarm will be triggered.

Now, coming to the Intruder Alarm System, it is an electric alarm system with a low-voltage electrical circuit that works with the assistance of magnetic sensors on the windows and the doors. So, whenever a door or window will be opened, the magnetic sensors will instantly detect the interruption in the flow of the electricity and will instantly trigger an alarm or any other warning sign.

Also, there are various other intruder alarm systems that apart from the perimeter sensors are equipped with the motion detectors that keep a watch over the larger areas outside an office or home. When the motion detectors detect or sense some movement in their periphery or range, an alarm is triggered to warn the owners and call the authorities. The most high-tech and highly advanced motion detectors are capable enough to segregate the suspicious movements of intruders and the nocturnal maneuvering of a family pet.
