This wasn't focused on the building so you last sentence is meaningless. They may have recorded digitally in 2001 but not for a traffic camera that really wasn't used for security. Even when it can be rerecorded then you can't keep it and 1 FPS DOES adequately show what it needed to show. Your whole argument is nothing more than "If I ran the zoo."
Maybe it is to you but I am trying to figure out what that Defense Dept video is about. The money they spend and this is all they come up with... But yes, the camera WAS pointing straight at the building.Why would they want to keep it, for keepsake? They had an automatic loop.
