Digital cameras are sensitive to IR light.

Have you read http://www.linuxtv.org/v4lwiki/index.php/Remote_controllers

Specifically,
saa7134: Most cards need only the saa7134 driver, but a few need the
ir-kbd-i2c helper. Boards known to require ir-kbd-i2c include the Upmost
Purple TV and the latest "i-series" Pinnacle PCTV boards (110i, 50i)

Otherwise, you might try the linuxtv mailing list.
