I would set it back to factory defaults, then set it back up from scratch.I am having a problem with this one camera.
during daylight hours - the camera suddenly looks like its suddenly losing its focus, blurring, then coming back a little brighter than normal, then returns to a good image.
all this happens in a matter of about 4 seconds, buts it doing it a lot, a causing alerts while it happen in blue iris.
this runs its course every few minutes to tens of minutes then stops for a while, then do this again maybe a couple of hours later.
This does not seems to happen at night, maybe only because I don't happen to get an alert from blue iris and see it happen.
Correct, it does not have a speaker output or one builtin.
