I want to record video of my podcast. Which camera should I buy?

Would like to spend less than $1500.
No recording limit. Sometimes episodes are up to 3h.
Power supply: good battery, or, ideally, would be able to plug in while recording.
Image quality: Would really like a great look, Sony a7ii is the benchmark here.
Low-light/indoor compatibility.

Everything else is unimportant: Will only use camera indoor in a studio, so it doesn’t need to be sturdy, or comfortable to hold, or small or look nice, or have clever placement of jacks, etc.
