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.

Closed circuit alarms are first choice for front doors for the fear of wiring being cut by burglars.

How does a sensor work, after all? In a wired system, a magnet pulls the spring loaded switch to close circuit when door is closed. When the door opens, spring retracts causing the circuit to break and triggering the alarm. The principle is same for wireless infrared system too. In place of magnets and wires, there are infrared sensors and emitters. If sensors don’t sense infrared light for reasons like opened door or other obstructions, the circuit is broken.

Burglar Alarms are also useful in protecting cars. FM radio based car alarms are getting popular because of their simplicity. They have a two part system: a transmitter, fitted to the car and a receiver which can be out side the car (home or office). The receiver makes noise when burglars move the car a few meters out of your porch. If the wireless alarm (transmitter) is disconnected from battery, remote alarm still remains activated because the receiver still continues to make noise. So this type of burglar alarm is highly reliable.

While installing, ensure you follow specified codes by insurance companies or certify it by third parties like Underwriters’ Laboratory etc. After all, you need someone even after burglar alarms are breached.

One very important decision that homeowners have to make regarding home security products is whether they opt for wireless or hardwired home security products. Obviously both wireless and hard wired home security products have their advantages and disadvantages. The decision to choose one type of home security products over the other is largely a matter of personal preference. This article will outline the advantage and disadvantage of these home security products and allow the reader to draw their own conclusion.

Wireless home security products certainly have their own advantages and disadvantages. For many the major advantage of wireless home security products is that the systems are easy and inexpensive to install. Home security products that do not require wires are so simple to install because you do not have to worry about installing complicated wiring into the walls. Another advantage of wireless home security products is that they can be easily moved from one location to another in the home. They can even be taken with you if you move to a new location. Finally another advantage is that wireless home products can be installed in locations where there is no access to a power supply because they have their own internal battery. Wireless home security products do have their disadvantages as well. One of these disadvantages is that wireless products often have design limitations that prevent these products from being placed too far from the central control panel. Another disadvantage is that wireless products require frequent battery changes.

Hard wire home security products are preferred by some but they do have both advantages and disadvantages. One of the most significant advantages of hard wire home security products is the reliability of the systems. Many consider hard wire home security products to more reliable than their wireless counterparts. Another advantage to hard wire products is they are usually installed by professional contractors and the work and parts come with a warranty. The cost of hard wire home security products is a definite disadvantage. These products are usually more expensive than wireless versions. Another disadvantage is that moving the parts is usually difficult and often impossible. The components of a hard wire security system are usually leased from the company who installs them and are not owned outright by the homeowner.

Weighing the advantages and disadvantages of wireless and home security products will help you determine which type of home security products you want to use in your home. In many cases the advantage of one system is the disadvantage of the other system. For this reason, choosing these home security products is mostly a matter of personal preference. Speaking to a professional in the industry can be an excellent way to make this decision.
