Capture card for intel nuc6i7kyk
There are no internal expansion capabilities in this NUC that could be utilized to host a video capture card. You can add such a device via USB, however. This NUC has support for the simultaneous connection of a number of USB 3.0 devices. Here is an Amazon search that displays a number of the devices available: https://www.amazon.com/s?k=usb+video+capture+device&sprefix=usb+video+capture+device.
Hope this helps,
