This is made from a new piece of footage, also three days long. This time the led on the camera chose not to light, so the flashes of red seen in the first draft did not appear. Instead, the PIR controlled lights outside the window were turned on this time, so at night time an unmoving, although intermittent, light source appears.
The focus of the Yi camera was set further way, so the closest opening is out of focus, and the furthest room (whose corner is just visible) is now in focus.
On two out of three days the sun came out in the late afternoon, and reflected off the windows of the rear elevations of the neighbour’s houses.
