Owl Cam Gives Your Spare Mac a Memory

Field notes

The app compares each frame with a frozen image of the empty room, using separate readings for movement, presence, and the stopping threshold. Its stated output is a set of ordinary MP4 files in a folder chosen by the user, rather than a proprietary archive. The page says an hour at a desk can become one clip instead of 14 motion fragments, with recording beginning three seconds before detected movement and ending only after the room is genuinely empty.
