The Wyze Pan v3 has secure boot fused as well.
Unfortunately for them, the implementation of it is broken because it only verified the first 32 bits of the signature, so thingino (a 3rd party firmware replacement) now just calculates it during build for that device.[1]
As for the camera being dead, do find out if it's just corrupt or something. Those line of cameras are fairly forgiving in regards to re-flashing broken images. (They have both microsd fallback and an ISP mode, I believe.)
Wyze as a company however have pulled their own firmware images from their support site, which kind of makes brick recovery painful. I don't know why they would do this.
