Also, home security systems now contain far more features then they ever have before, so they perform more functions as they have become more convenient and easy to use. One surprising feature of a home security system now is carbon monoxide detection capabilities that can actualy save the lives of you and your family. Many people are unaware of the fact that people are killed every year while they sleep in their homes by carbon monoxide gas that is produced and pumped into their homes by a malfunctioning gas heater.
Even charcoal Bar-BQs have killed people that inadvertently used them in a confined space. Carbon monoxide is a colorless and odorless gas that has no symptoms as it kills, so the hapless victims simply fall asleep and never wake up again. With a modern, high tech home security system, sensors located in the home will sound the alarm if the deadly gas is detected and axiomatically call for emergency help.
Another added feature of a home security systems is fire detection capabilities that uses sensors in the home that signal the system to sound the alarm and call the fire department is high temperatures are detected inside the residence. Of course the basic function of a modern state of the art security system is and always has been to detect and prevent break-ins to the residence and any other buildings on the premises.
Using advancements in technology such as micro-electronics a home security system now functions to protect property and its inhabitants far better and more conveniently then ever before, while the over all cost of these systems has dropped considerably. New technology in body heat and motion detectors has rendered them far more sensitive and smaller, meaning that they are now virtually impossible to detect.
ADT systems now even has the ability to install a thirty-five foot security perimeter around your home that will detect anyone who enters it once the system has been activated. The sensors they use are so finely calibrated that they can differentiate the difference between a man and an animal such as a cat or a dog, completely eliminating the chance of false alarms.
These same ultra-sensitive heat and motion detectors are used inside of the home or business to detect anyone who is inside, on the slim odds that they have made it that far. So while the older alarm systems had the capacity to detect an intruder that entered through a door or a window the modern alarm system has multiple layers of security that begin on the outside perimeter of your home.
