Horizontal black lines moving vertically!

I just set up my Ring wireless doorbell 4 and it has several horizontal black lines that move from the top of the picture to the bottom. It’s not a lense flare and my signal strength is RSSI-56. It’s mounted on an external metal door. It only started doing it after I mounted it to the door. Has anyone had a similar problem? Is it signal strength related?

Hi @RingBearer1. It’s possible that the metal door you’ve mounted your Ring Doorbell on could be causing some interference with the signal. Especially if this only started happening after you put your Ring Doorbell on the external metal door. Try putting the Doorbell somewhere else that isn’t a metal surface to test if these horizontal lines still appear or not, as that will narrow down the cause.
