This means that an intruder no longer has to enter a building in order to be detected, because he will trigger the alarm as soon as he is detected outside. They have
range of thirty five feet, operate day or night in any type of weather conditions and can easily tell the difference between a dog, a cat or a human. This means that you will never have to be bothered by false alarms and you certainly won’t have to contend with an intruder in your home. Another thing that has made todays security systems far more effective and reliable is wireless technology, that improves systems in a number of areas. Prior to wireless technology, a security system was connected by a series of wires running throughout a building and just
like you have seen in the movies these wires could be cut to disable the system. Not only that but monitored systems had to be connected to the monitoring station by a land phone line that could also be cut to disable that end of the system as well.
