The 482xPro series of "Digital" outdoor perimeter protection microwave barrier systems, manufactured by Cias Elettronica of Milan, Italy, have exclusively designed digital signal analysis. The 482xPro series outdoor microwave systems are a direct replacement for those outdoor systems that are false alarm prone and use analog signal processing. These field-proven outdoor perimeter microwave barriers use a unique and exclusive internal microprocessor and "Fuzzy Logic" to analyze the received signal from the transmitter offering extremely high intrusion detection probability at all intruder speeds while providing a very low false alarm rate.
