A MAC is symmetric and can thus only be verified by you or somebody who you trust to not misuse or leak the key. Regular digital signatures is what’s needed here

You sign them against a known public key, so anybody can verify them.
If it’s just the cameras owner attesting, then just have them sign it. No need for expensive complicated circuits and regulations forcing these into existence.

You can’t use a MAC for public key signatures. That’s ECC, RSA, and similar.
