Preroll video blurred top and bottom

Hi, I bought a Ring Doorbell 3 Plus, and it works a treat now it’s set up. I am a bit puzzled, though, that the preroll (black-and-white) video has a blurred bar across the top and bottom, while the middle is nicely sharp. Is this by design or is there an issue?

Hi @jem70. Thank you for attaching that photo of your Pre-Roll for your Ring Video Doorbell 3 Plus! To answer your question, yes. This is exactly how the Pre-Roll should look. You can find more information on Pre-Roll here.
