That's a decent test for determining if the camera will be suitable for infrared photography.

It helps if the camera has live view, as in being to view the shot the camera would take in the LCD display. That way, you can see the IR remote beam going on & off. Failing that, just take a picture with the remote aimed at the camera while pressing a button on the remote.

*EDIT* this is done with the IR filter mounted to the lens.

your 400D has a built in filter that is designed to stop Infrared light getting to the sensor and let all visable light pass thru. A IR filter fitted externally is designed to reduce as much as possible the visable light getting thru & permit infrared inhindered. The combination of the two results in really long exposure times - suspect to see a TV remote you'd need to be using at least 30 seconds with as big an apeture as you can get.
What are you needing to achieve?

Extinctionjet,
If the TV remote uses IR light (which most do), then like others said a long exposure with wide open aperture is needed to see the IR light from the remote.

its very dim but ill try with a higher apature and let you know. :)
