The Canon DSLR runs on a separate engine than the USB Cameras, despite connecting to your machine via USB. To get Eclipse to pick up the feed from the DSLR, go to the SLR Capture tab (making sure that your DSLR is on and connected). If you still have connectivity issues, turn off the DSLR, and unplug it from the machine, then plug it back in and turn the camera on. If you cannot access the SLR Capture tab, you do not have a Pro License on your dongle. If you ordered a Pro License, but this tab is grayed out, we will send you an upgrade file to fix the issue. Just give us a call!
