N900 can see IR, see the image attached (not the best, but I think it proves the point).

Ok I see, maybe its just another frequency. I tested only the two remotes in my office and the IRDA of another phone to check. But thats not anything like I see on my other phones/cams. This looks like a candle compared to a car on fire.
I will have a look for an IR torch with different frequencies... might never come back though... the basement is like a dungeon and I am aware of dragons...

Look straight down into your n900 lens, see that shiny red thing?
That is the infrared blocking filter

Sorry but why the cam is blocking IR? The camera works bad if it get IR light?
I want to take some IR pics but normal ones too. So I don't know what is the best: leaving or quiting the IR filter?

Basicaly, the pixel responsible for registering red light are also sensitive to IR light. But they cannot distinguish between red and IR.
So you need to filter one of the two if you want any meaningful picture.

Aah ok but there are no always IR light in the environment. Just testing indoor for example there are near nothing of IR light.
Outdoor sunny day have much more IR light. But cloudy there are a few IR light.
So I guess if I quit the IR filter I will get bad pics only in sunny days. Just of course the best time to take landscape pics. But that is acceptable.
Am I right?
Anyway I just noticed that the N900 cam is not so good to take IR pics. And as I can see, it is very difficult to take out the IR filter. So I don't will try it, I guess can damage the Carl Zeiss lens :P
But, why just the IR light is white in the display and not red if it is only captured with red pixels sensors?
And as you can see in TV it is greenish not red. I don't understand that, lol.
Thanks to all.
