Toggle between Multiple USB Camera

Overview

This example acquires images from a gige or usb camera using the IMAQdx driver which is part of the Vision Acquisition Software. It's possible to toggle between multiple cameras by selecting the camera name input.

Description

Some USB camera drivers are not capable of acquiring from two cameras simultaneously.  Since the IMAQdx driver goes through the camera driver, if the camera driver is unable to acquire from multiple cameras simultaneously, then IMAQdx will not be able to acquire from these cameras simultaneously.

But if you would simple like to be able to toggle between multiple USB camera, you can use the following example for it.
