|The Rednet ® Series of photobeams is a range of active infrared sensors designed to combine high levels of intruder detection with a low potential for false activation.The system utilises the infrared transmission to synchronise transmitters and receivers and removes the need for hardwire synchronisation cables between towers.RN4 systems feature four high power transmitters and four receivers. Uniquely, each transmitter operates to all receivers and all receivers are operated by all transmitters. This combination creates a sixteen beam path ‘net’ which is difficult to compromise.
The Rednet ® system is simple to design and install as it is modular and has just five main components.
The Rednet ® beam head contains a folded optical array to combine a long focal length with small head size. This creates narrow transmission and receiving angles to maximise performance. The heads also contain their own heater to ensure that the maximum amount of energy is directed to the section of the tower the beams operate in.
