I just got one delivered today. 3 black lines. Used eyeglass cleaning cloth on lens and still there. is this part of the sensor normal? I have only tried mine in my office. Was going to mount it to see if it clears up. Different lighting outside.
I am replacing my doorbell, we'll see if it is a HW or SW defect.
Few things I noticed are that it doesn't happen when in night vision mode, happens when it is dark outside and there's some external source of light, turning on/off the light above the doorbell temporarily resolved the problem.
Sorry for the late response, but I wanted to drop in here to help.
I understand that this issue can be frustrating but I definitely wanted to stop by and see how I could help.
Just wanted to double check to see if you were still needing help on this? If so, what troubleshooting steps have you tried?
Please let me know.
