I’m sorry if I mislead you, but no the WCO does not detect “anything moving”.
The way it works is the WCO only starts recording when it’s PIR is triggered ( meaning it detects something move that is a different temperature than the surroundings). After the recording is made the servers looks for any people in the recording and it is flagged for “People” if one is found.
The V2 on the other hand is always “watching” because it doesn’t run on batteries. So it detects the amount of pixels that change from frame to frame to determine if something has moved. For this reason a V2 can detected a person on the other side of a window and WCO cannot.
