Here’s an answer from another thread-if you let the camera pick up an IP via DHCP at the c8:02:8f:xx:xx:xx address, it should pull down its firmware and update to a Wyze MAC address.
“Wyze cameras are manufactured in China. Most of the camera parts are purchased from China too. Nova is one of the suppliers for out manufacturer. When our camera boots up, it has an original MAC like c8028f. Wyze purchased our own MAC range which register under our company name, they start wit A4DA, 2CAA, and may be others in future. During our device boot time, our program will ‘overwrite’ the device MAC to be a uniquely assigned Wyze MAC. We have see occasional report of device showing as c8028f MAC. It is rare and not none. This is very likely to be the ‘overwrite’ failed for some reason. We are chasing the issue but it hasn’t been resolved yet. No matter what MAC the device uses your device should be functioning fine (unless you have one MAC address blocked through your network).”
