Photo Electric Beams

DOUBLE MODULATION
Almost all infrared beams available on the market use a simple process called SINGLE MODULATION. However, the single modulation signal is easily duplicated by various sources of infrared light emission. The ability to reproduce infrared signal by other infrared emitting devices makes it possible to breach the perimeter security system undetected. This compromises the reliability of the system.

All TAKEX Intelligent Synchro-Quad and Super Twin infrared beams use a patented process of infrared signal at two frequencies. The unique pattern created by this process cannot be duplicated by other infrared light sourcecs. To further aid this process, the receiver contains a patented PHASE LOCK LOOP circuit that locks on to the double modulated signal, and ignores other forms of infrared light. This patented process assures you of a high integrity perimeter system that will with-stand attempts to defeat it.
