What You Need to Know about Burglar Alarms

While no one disputes the necessity of installing a burglar alarm system in the home, there are those who are still unsure of which products to buy, given the wide array of choices available. To get the one that is right, you need to know some basic facts.

Burglar alarm systems today can be classified into two types: the indoor and outdoor varieties. Both can be used in residences and offices, while large perimeter areas that need to be secured are best protected with outdoor alarms.

Indoor Burglar Alarm Systems

Each system or kit will have their own distinct features, but in general most will include a passive infrared detector, or PIR. This device is relatively inexpensive and quite effective; it functions by evaluating the temperature in the room or environment it is placed and when someone breaks in, this burglar alarm device will be able to sense it.

Another common feature in indoor burglar alarm systems is the ultrasonic detector. This gadget emits sound waves which, if an intruder where to enter the room, interrupt the flow and trigger off the system. A device that works in a similar fashion is the microwave detector, which relies on microwave emissions.

Another common feature in indoor burglar alarm systems is the glass break detector. Once these devices are installed near glass windows or panes, it will automatically trigger off sounds, penetrating walls throughout an edifice.

A photo electric beam, on the other hand, functions by emitting electromagnetic waves such as light or infrared. By putting up three or more beams in an area, it becomes very difficult for a break in to take place without triggering the device.

Outdoor Burglar Alarm Systems

Among the most common features in these systems include the inertia sensors, which rely on the premise that the intruder will make contact with the object where this gadget is installed, triggering off the alarm. A passive magnetic field detector consists in part of wires that are placed on a wall or placed underground. The system works by assessing any changes that occur in the magnetic field around the perimeter.

The E-field is another outdoor burglar alarm system that works in a similar vein, and relies on electromagnetic frequencies. To hinder any attempts to infiltrate chained fences, microphonic systems are employed, and taut wire fence detectors function in the same manner.

This introduction to the different types of burglar alarm systems should now enable you to better understand the devices that you need. As you get more familiar with the terms and jargon, you’ll be able to make the proper purchase.
