850nm is suitable for outdoor and strong light use;
760nm is suitable for indoor and weak light use;
720nm is suitable for indoor and weak light use;

Anyone can answer? Use mod on cam or use filter

My Canon G2 is modded with a 715nm filter, allowing false colouring (similar to R72 720nm filter), which is fun.
I just got a 1000nm filter from ebay (~$25) which I can attach to my camera to block out even more.
Modded cam is easier though, but the camera will be dedicated to IR if the filter is installed inside, which is great
