So, this provides the lever to start discussing physical buildings as networks, which is a rich conversation, but I think your mention of the log is actually even more illuminating, because it points out a current (I think quite serious) issue in most electronic locking solutions. More often than not, they do not log the actual opening of the door, only the successful or failed authentication. So, if you can bypass said authentication to open the door[0] there is no record of the door having been opened by anyone. Logging in the physical security space is both important and incredibly overlooked.

the logging is in the camera system; Most camera systems have ways of saying 'fast forward to the next movement' as well as a way to say 'show me what things looked like at time X' - so in a real way, the DVR /is/ the log. I'm mostly familiar with electronic locks and cameras in the data center context, and in that context, yes, there is a completely analog key that often opens everything[1], but then there are electronically fired locks, and, of course, a camera. There is camera software that will time sync with the electronic lock and show you what user had authenticated while showing you a video of the user entering the building. I don't know of any systems that correlate cameras with key use, but the motion-sensing thing should do at least part of that. (There is also usually security sitting up front, but especially in the early AM when it's just us grunts? those folks are often not paying a whole heck of a lot of attention.) [1]well, on the fail secure systems, anyhow. the mag-locks that are 'fail safe' - that open on power failure usually don't have an obvious manual key override.
