Facts on the Inner Workings of Alarm Systems

By: David Johnson

During the past three decades the level of technology that is found in alarm systems for homes and business has greatly improved and now they are more secure and reliable then they have ever been before. Thirty years ago an alarm system on a home or business basically consisted of trip mechanisms on doors and windows, that were connected to a control panel, that was connected to an alarm and that was it.

For someone who was familiar with the level of technology that went into these early systems they were a cinch to bypass and most of the time all that was required was a pair of wire cutters and that was all. Two things have happened since that time to make alarm systems far more reliable, one being quantum leaps in micro-electronics technology and the other thing that happened is a a rethinking of just how an alarm system should function.

For instance now an alarm system will have more then one layer of security, that actually begins outside of the building that is being protected. It starts out on the front lawn and windows where a sign and decals will notify prying eyes that that home is equipped with a home security system. Thirty years ago this would have worked on the amateur thief but due to the known reliability of todays systems even skilled professional burglars will pass up a home with an alarm in favor of a home that is left unprotected.

The next layer of security begins thirty five feet from the home or business, where a broad perimeter of the building is guarded by a series of state of the art body heat and motion detectors that will sound the alarm if this perimeter is entered. These state of the art sensors are so accurately calibrated, that they can easily differentiate between a man and animals, such as dogs and cats, so there is never a chance of a false alarm.

The next level of protection is at the doors and windows, where high tech trip sensors protect each opening into the building from unauthorized entry. Due to state of the art wireless technology, these sensors can't be bypassed by cutting a wire like you have seen in the movies, because there is no wire. They are battery powered and will signal the control panel every three years when their batteries begin to run low, so there is never a chance of batteries going dead.

Then there is yet a fourth layer of security that is made up of body heat and motion detectors that are hidden inside of the home or business, that prevent anyone from moving around if they have found themselves this far in the security zone. For business people who worry about someone hiding out in a commercial complex during operating hours, these sensors are the answer. Then the whole system is backed up by an auxiliary power source that can run the whole system for weeks if it has to, should the main power supply be cut off.
