Hi, I've been thinking on building a night and day vision camera. I think its very straight forward, but I just wanted to have a look at your personal opinions before going any furtherer.
The idea is very simple: As you probably all know, digital cameras are able to "see" the visible spectrum, but also, some frequencies higher (I think), and lower. You can try this by pointing with a remote control to your camera, you will see a white light.
The fact is that the LEDs on remote controls are not powerfull enough to be reflected and seen by the camera. But I think that with a more powerfull infrared LED, or LEDs, it would be possible for you to see without being seen.
I've tought on puting the LEDs just as conventional bulbs in a torch, this way, all the light will point towards.
I think, and correct me if I'm wrong, that this is what some security cameras use, the problem is that they are ti expensive.
