PIR Operation

PIR (passive infra-red detector)

All PIR sensors detect changes in infra-red radiation, in the form of heat emitted by a number of bodies including people, cars and to a lesser extent, dogs or other small animals. The bigger the body, the more infra-red radiation is omitted and the easier it is for a PIR sensor to detect.

If you imagine the images shown on television of a Police Helicopter following a suspect in the pitch black using night vision technology or a Soldier looking through night vision binoculars in the middle of the night, this is exactly how the PIR is working.

There are two ways of fitting the PIR (the PIR is supplied with an easy to fit adjustable mounting bracket):

1 - 1.5 metres from the ground, pointing horizontally across the ground (this is the most efficient way to avoid false alarms from small animals).

High up pointing down towards the ground, but you will need to experiment with the angle to avoid detection of the ground.



  • The operating range between the PIR's & Receiver is 80 metres (line of sight) which equates to approximately 40 metres after taking the walls of the house into account.
  • PIR's: The Wireless PIR's are powered by a 9v PP3 Battery which will last for between 9 - 18 months in most applications, they have a 13 metre Detection range and is supplied with a specially designed rubber hood.
  • Receiver: The unique 4 x Channel Receiver can operate with up to 16 x Wireless Sensors (4 x on each channel) and is powered by a plug in transformer, 4 x AAA batteries can also be fitted into the rear of the panel to act as back up power in the event of a power cut.
  • Alert: Beep (the system can be set to give an audible 'beep' for approximately 6 seconds following an activation, this beep will identify which channel has been activated.
  • Alarm: The Receiver has a built in 100 Decibel Siren which can be turned on at any time by using the built in keypad, remote control or wireless keypad.
