I think the privacy zones take a few mins to refresh if you had just deleted it. I noticed it stays there until I go back into privacy settings like 2 or 3 times. Then it clears. If you wanted to readjust the box, you need to make sure you click on the box you want to adjust, then after readjusting and saving, it will look like you have 2 boxes until a few mins or a few refreshes out and back into privacy settings. The box shouldn’t move on its own though. Not unless you accidentally set up more than one. Just be sure you are clicking on the correct box if you have more than one, it will say privacy zone 1, privacy zone 2…etc.
Yeah the lagged refresh and update of the saved zones suck for sure though I totally agree 100% on that. However I think the adjustable square is workable… Not like a circle would be that much more of a difference in setting up a zone. If they made it like the motion zones it would be perfect but in reality, who would need to set up a privacy zone needing that many points? I figure privacy zones would tend to be small areas out of the camera recording frame?
And by the way… the privacy zones are meant to not trigger camera recording for anything detected in that box, it’s not meant for blocking your view of that spot. Like setting up a zone for your neighbors window of they are in view of your camera… Or in my case, I set up a privacy zone right where my car window is since I tend to sit in my car which is on my driveway, and since it’s in the motion detection zone it would trigger multiple notifications. So with the privacy zone, I won’t get multiple notifications just for turning my head or looking up while I’m in my car. One thing to note though, that box stays set there… So for example in my case, if i move my car, there will be a little black box on my driveway where it will not trigger detection for recording… Although you are the only one who knows that fact so I highly doubt that will make any difference in terms of security.
