Burglar alarms have become things of common place in almost all super stores and business set ups. Private homes are not left out too far behind. Advancements in technologies and competition in the market have brought down the rates to around $10 for a basic alarm system.
How Does Burglar Alarms Work
Wired alarms are almost extinct. Wireless burglar alarms operate by either of the two means, today.
1.Connected by radio frequency
2.Connected by infra red light rays
Wired systems required power to operate continuously unlike the wireless alarms which run on battery power. There is the third type, which combines the features of the earlier two and is known as hybrid alarm.
Burglar alarms operate on simple principles. When their ‘connection’ or circuit cuts, they get triggered. When intruders pass between two sensors or a door opens it is detected by their cut circuit.
Normally there are 2 types of circuits; open circuit systems and closed circuit systems. Let us not get into jargons and cliché words; closed circuit operates when the door is closed as electricity begins to flow. But when interrupted by opening doors, circuit also opens and the alarm goes off. And it is the exact reverse of this in open circuit alarms. The siren is triggered when doors are closed.

The world today has a plethora of advanced technological means of protecting their valuables be it jewelry, an expensive electronic gadget, piece of art, or antique that you have paid a fortune to make yours!
However, with all good things, there is something bad and security systems are no exceptions! This means technology too can fail!
Looking at the brighter side, like I said all your hard-earned valuables could be protected today without your having to worry 24/7 whether your favourite diamond ring or antique Chinese vase is no more yours when you get back home after a hard day at work!
However before you embark on a search for the best security system for your home, you need to do a reality check. Your best option is to ask your family and close friends- people you trust, about their security systems if they have one. Take a note of all the problems they may have had with their security systems since they installed them. This will help you to cross-question all the security firms that you visit and hence clear your doubts too!
Another important consideration is how much are you ready to shell out to secure your home, now I do not mean just buying the equipment required because the expenses do not end here. If you want a complete security system, you also have to consider paying the security firm that is going to monitor all the events while you are away!
Now to give you a lowdown on the options available to you,
One you can go in for a do it yourself kit, but again I suggest this option only if you are confident of setting up the system and of coarse also if you want to save on costs. However if you goof up, you are obviously going to be spending a lot more then you thought of saving in the first place!
Second, you can visit a security firm who will give you a customized system according to your requirements and budget, they also monitor all the events 24/7, and you will be charged for these daily services. For the best firm in the market and of coarse one in your area you can you can search on the internet or again ask friends and family.
To understand the technical jargon in layman terms you can read on.
In terms of location, you have:
Perimeter alarms
As the name suggests such alarms are usually used to stop the intruder at the boundaries of your property. They are fairly simple in design, why? The answer is simple; because while guarding a perimeter your aim is to stop the intruder outside and hence will want to sound an alarm if somebody crosses the boundary because if they are inside the your property your alarm was ineffective! Simple switch circuits are very effective for such purposes. Good examples of these are the open circuits and closed circuit alarms explained later on in the article.
