I am using 2 webcameras of Logitech with IVision toolkit to parallel acquisition. Why it is needed to limit bandwidth of cameras? To have it optimized I had to limit to about 10kb for one of them and to 1014kb for the other. Is it posible to use NI IMAQ USB toolkit to do aqcuisition?
It should be possible to use the NI IMAQ for USB Cameras driver to acquire your images. Unfortunately the iVision toolkit is made by another company and I am unfamiliar with its use.
