This is a suggestion for the newest motion detection zone setting. Would it be possible to do the opposite of what you currently have programmed? Meaning have an option to draw a box around a spot to not detect motion. So then motion would be detected on the full screen except for where the box is drawn.
I will forward this suggestion to our Dev team. I am not 100% sure if they will be able to do this to be honest but its worth talking about!
This is known as masking. Imagine taking masking tape and placing it over an area in a picture you didn’t want someone to see then show them the photo. A pair of scissors does the same thing, the trick is to uncut the photo when you are done!
