That's simply not possible. MAC is hardware encoded it can't be changed.

Actually it is possible, But rather unlikely. I know that this brand can do that, (The Dahua one) https://www.rrb-security.nl/camera-bewaking/.

I've seen it happen before with certain alibaba cheap dvr recorders as well. If you'd reset it it might change back

That would still be spoofed, not physically changing it. It's a software change not actual hardware.
