The very short second site visit took place between 14:32 and 14:35 today. It’s also cloudy today. Being an artificially lit place, there was no discernable difference in lighting conditions in the second-floor corridor. There were classes going on in the two rooms, and a quick peek showed that the rooms are in fact quite well lit. On the 5th floor, the thing turned out to be an outward-facing spotlight, not an inward-facing camera. The open space looked fine in the afternoon, but we might have to wait until some sort of prototype is made to know if there really is going to be problems with the ambient lighting. There were also classes in the two rooms in that open space on the 5th floor. A quick peek showed that they are pretty well lit too.
