IDRANet modules can receive/transmit IR remote control signals compatible
with most equipment. This enables interaction with IDRANet using remote
control handsets and also allows IDRANet to control most A/V equipment.
   
Codes can be learnt from most handsets
Receiver modules are capable of relaying IR data to the network for IR
  redistribution (extender) functions
Receiver modules can be taught to recognise codes such that an arbitrary
  handset can be used to control IDRAnet functions or to request information
Transmitter modules allow IDRANet to control existing A/V or other such
equipment. For example, you can phone home and get the system to action
your DVR to record that program you forgot... you could also get it to turn off
  your IR controlled air conditioner unit...
