160° Fisheye Night vision Module - not fisheye image?

What resolution did you set it too? Just so you know, I don’t have one. I do have several of the Normal Official V2 cameras. I can take portrait or landscape images depending on which way the camera is positioned etc. Mine are all being used in Motion Eye OS, video mostly.
