Observing infrared light from IR LEDs

Many people has asked me weather is possible to observe infrared signal emitted from the Irdroid IR LEDs with a naked eye . The answer is no, however one can observe an IR LED flashing with a camera, pointed to the Irdroid devices. The Irdroid modules has two IR LEDs which use half period rectification in order to double the 19khz carrier and to make it 38khz standard remote control carrier frequency.  When you point a camera toward Irdroid infrared module , you should be able to observe the two IR LEDs flashing when a button from the Irdroid app is tapped and a command is sent.
