Concept
The Rednet series of photobeams is a range of active infrared detectors 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. System Design The Rednet system is simple to design and install as it is modular and has just five main components. To design a system, simply decide where the towers are to be positioned and measure the distance between these points. Choose the wall or free-standing towers and select the correct beam set for the distances between them. Towers come complete with all fixings and the electronics include heaters, thermostats, fixings and alignment aids.  Beam HeadThe 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. |

Concept
The Redwide is a rugged external wide angle passive infrared detector. It is designed to provide reliable intruder detection at distances of up to 50 metres over a 30 degree span. These detectors are ideal for use as motion detection devices for CCTV systems. They can be used to activate video transmission systems, position, pan & tilt or dome cameras, or alert an operator to movement in a specific area. Features

Concept
The Redwall 100Q is a robust external long range passive infrared detector designed to operate at ranges of up to 100 metres. As a single-ended device it does not require a transmitter to be mounted at the far end of the protected area reducing both installation time and cost. The Redwall 100Q is the first long range external detector to incorporate quad element technology and represents a mojor step forward in the design of this type of sensor. Ideal for use as a motion detector for CCTV equipment, the Redwall 100Q can be used to activate phone line video transmission equipment, recording devices or alert an operators attention to movement in a specific area.
