I use Cam Plus on my Video Doorbell Pro which is running on battery.
Because it is a battery Cam, it will give you options to set a cooldown for the VDBPro recordings and to limit the recording length.
I personally just set mine to no cooldown, though you can choose anywhere from 15sec, 30sec, 45sec, 1min, 3min, 5min, No Cooldown.
I also set the Max Video Length to 3 minutes, but you can choose 15sec, 30sec, 60sec, or 180sec.
You can also limit it to a schedule and reduce the motion Detection Sensitivity or a Detection Zone to help (I mostly just block off the road/sidewalk).
I have not seen that update message before, so I don’t have anything to say on that, but I appreciate you sharing. I will keep an eye out and see if we can figure out why it would say that when you are up to date already.
