subject: The Different Types Of Burglar Alarm Devices: Which One Suits Your Need? [print this page] Alarm companies offer a wide variety of burglar alarm systems, each built with a specific feature and function. As normal force sensors may not be applicable to all types of burglary, there are other sensors that can cover specific situations. Using a combination of these different kinds of alarm systems increases the chances of averting crime and capturing the culprit.
Infrared. Changes in temperature of a particular area can be used to determine criminal activity. Infrared sensors perform this tedious task. The sensor acquires the temperature of the area in normal conditions and raises the alarm if there is a sudden spike. The change comes from the body temperature of the culprit entering the area, the infrared sensor detecting the change and raising the alarm.
Glass break. Statistics show that most burglars force their way into a building, meaning they can break through windows to get in. Glass break sensors can prevent window entry by raising an alarm when it feels the shock resulting from the force of breaking glass. These sensors are ideal for perimeter protection especially where there are many windows.
EMF. An acronym for electromagnetic field, the EMF system senses changes in the magnetic field of an area. Alarm companies design these sensors so that they can be buried to the ground, useful for covering an expanse of open field. If the burglar is carrying something with metal, most likely for breaking in, the EMF sensor can spot him.
Lasers. This kind of alarm system is commonly seen in movies, but they can be applied in real life, as well. A laser alarm works by triggering an alarm when the laser is broken, meaning someone is blocking its beam. Alarm companies Long Island clients trust create this system to provide maximum security for, say, a museum housing priceless artifacts.
Sound. Alarm companies New York clients trust also have alarm systems that use sound or microphonic sensors. These sensors are placed in wire fences, triggering an alarm at the sound of someone cutting the wire or climbing over the fence. This system works similarly to alarms that detect force. It also has a high rate of detecting burglars.
