IR source detection on a screen? Answered

Hello everyone,
I'm trying to find a way to detect a IR source -a LED- from 100m. I only need to detect the source, I do not need to transmit data. 
When I turn the camera towards a IR source the software would put an icon on the source BUT without seeing the beam. Namely, the led should look like it is off but the icon on the image should indicate that it is a IR source when it is on.

Thank you all!

You can read the sensors on a Wii remote, which will show IR and nothing else.

No, the Nintendo Wii game remote has a 1024 x 768 IR sensitive camera in it.

And avoid sunlight because most of it is IR overpowers any Infra Red fQ LED that exists.

I have seen people using Python Image Processing to do something like what you are describing. check this out. I haven't delved into this yet myself, but I know similar problems have been solved using that approach. As per the camera, You could remove the inferred filter behind the lense, or just buy a proper Low-Lux camera.

Well most cameras are going to show the IR light as a visible spot on the screen. If it doesn't then it can't see the IR light to start with. Typically IR tracking is done with an IR camera. So if you find a camera that doesn't see the IR then pair it with an IR tracking camera.
