Old way of marking a detection area was by creating a single rectangle of whatever size the user dragged into position.
… a new way of marking a detection area suddenly appeared on the cams using multiple small blocks (like tiles) which can watch/ignore specific small spots (tiles) that did not have to be connected to each other.
Keeping this in mind, I have discovered two problems.
The new small block area method (tiles) setting would sometimes vanish and resort back to the old way of a large rectangle detection of a random size, and the small block area (tiles) would be lost.
Motion was being detected in areas (highlighted by the old large rectangle) which included areas ignored by the small block method (tiles), although the new small block area method (tiles) setting hadn’t been lost.

It’s not shadows. It’s not signal.
Viewing camera live is always perfectly fine.
