Streaming from analog and digital sources

Hey folks, I'm working on a project where I'd like to stream content from digital and analog sources. In particular, I'll be using multiple cameras (two analog handycams from the 2000s and a modern DSLR) as well as video from a vhs player. Can anyone point me to an appropriate capture device that will let me feed that content live into my PC? I'll be using VDMX to create some mixes and animations from the 4 sources.

Thanks!
