Improvements in security systems live some of the most uncertain of our recent history moments. This is moved to different areas, but one of the most alarming is that refers to security. The insecurity is a fact. Nor is no reason to panic, but it is clear that any business or any home needs to have security systems so that unwanted events do not occur. These security systems have evolved over time, in the same way that there has been an evolution in theft systems. The locks are much safer than before, and almost everyone has a more or less protected door in the entrance of his house. Similarly, the alarms are no longer limited to an acoustic signal, are now connected with services of private monitoring that can themselves at our home in a matter of a few minutes.

Home Security: alarms beyond locks, security doors and other protective mechanisms, the alarms have a great credit within systems security of the home. It is logical. They are reliable, accurate, and little given to failing. Let’s see how they work. As a general rule, an alarm has at least three parts: central, keyboard and sensors. The central part, as its own name allures to, is something like the brain of the device. It coordinates all signals, both input and output, and is that the Auxiliary battery, so that in case of electric suspension alarm can continue to operate. It is not difficult to imagine the keyboard function: through the program the alarm and also has a panic button, to indicate to whom it may concern in case of immediate need. Finally there are sensors that report to the central unit any suspicious abnormality.
