Deviant Ollam's two-hour conference talk explains how elevators work, from the pit and buffers to the car top, controller logic and access-control features. It shows how this knowledge can be used for optimization and for bypassing building security.
HN commenters call it an absorbing, entertaining deep dive on elevator security and the go-to link whenever elevators come up.

Deviant Ollam does another talk with elevator consultant Howard Payne just about elevator security which is fantastic. It's very similar to this one, but goes deeper into the single subject. There are a few versions on YouTube of various lengths, but here's the 2 hour version: this video
Yes. That's the shorter censored versoion. I recommend the full 2 hour version, with all the secrets: this video My second favourite talk: You spent all that money and your still got owned: [LINK] I even watch these again and again.
And watch this[0] entire (super entertaining) talk from Hope X about elevator security. You get a pretty good feal for how the safety measures work after watching it. [0] this video
I ran into this video (Elevator Hacking: From the Pit to the Penthouse) awhile back, and it was so interesting to me that I ended up watching the entire 2 hours in one sitting.
If you feel like going down an elevator rabbithole, Deviant Ollam has quite a few talks/videos about all sorts of niche elevator stuff. My personal favorite: this video
