Hello, I have a question about ni imaq for usb in ni vision builder ai 3.6 (I have made a vi with imaq and I run it in vision builder) and I want to know how I can connect several web cams to the computer and how many of them can be connected. can they all be from one brand and one model and can they be run with one driver installed on the computer?thank you

Hi, In general NI-IMAQ for USB can only support one camera at a time. You can acquire from multiple cameras (non-simultaneously) by using the IMAQ USB Enumerate Cameras VI to identify each camera plugged into your system and access them through the other IMAQ for USB VIs. I would also like to point out that Vision Builder AI does not support the NI-IMAQ for USB Cameras driver. It is designed to solve machine vision applications but USB cameras usually don't provide the triggering or advanced modes necessary for machine vision. Because machine vision and USB cameras don't usually go together, we didn't provide support for USB cameras within Vision Builder AI.

Machine Vision
