Do you know your led model , or are they "plain IR leds" ? If they're narrow beam leds, you can widen the beam by sanding the led case flat near the chip inside of the case. I´ve read that some webcam´s have an ir-filter build in Basically EVERY webcam has a builtin IR filter. This filter is needed for normal operation of the webcam. this ir-filter should be build out You only seldom HAVE TO ir-mod your webcam. But IR leds work far better with an Ir modded webcam. It's your choice. My hint would be : - try without modding your webcam, since once modded, the webcam isn't suited for "standard use" anymore - If it works well, stay with an unmodded webcam. regards

If it doesn't solve your prob, then it's still time to unmount your webcam's IR filter. just my 2 cents opinion cya.
