Home security is an issue which must be of a significant concern to everyone. Whether a person buys a cheap home security system or an expensive one he or she should see to that they are able to install as many security features as possible because they are now so affordable, it has become common to purchase.

The burglar alarms are useful in catching the burglars red handed at the moment of burglary. The moment the burglar breaks into the place, the alarm sounds and everyone will be alerted.

Now-a-days are wireless security systems are often used, due to the some setbacks found in the wired security systems. The burglar has a chance to break the circuit wire in the wired security system, so that the alarm maynt work. As radio signals are used in wireless security systems, any intervention caused by the burglar is absorbed by the sensor, which in turn sends a radio signal to the alarm, and the alarm sounds to alert everyone.

The security systems consist of control panel, sensors like motion based passive infra red sensors, door magnetic contact, smoke & gas leak detectors, telephone dialers with recorded message & hooters/sounders.
