Action cam/Camcorder Advice

Yeah it sounds great.

Did make me think about what audio I’ll want to be recording, too.
Do I actually need two XLR inputs?

One way would be to get some nice jack to XLR leads and plug into the line-in, for sure.
But actually do I need that option?
Could I just use any camera’s external mic input and whatever converter cable was needed? (Assuming the camera in question actually has an external mic input).
If so, am I better off paying for the Sony ZV1 as it has a camera too, and just connecting audio via it’s mic connection.
Sorry, I’m just thinking aloud more than asking questions now.
