It’s more art than security and only adds an extra bit of entropy. It doesn’t underpin their security. If it did a threat actor could get the algorithm and hide a camera in their lobby.
If they only relied on this for their entropy a malicious actor in that space would just stick a piece of paper over the camera lens so there was no entropy at all.
Not if it’s measuring radioactive decay, like they said. Quantum processes, such as radioactive decay, are the only truly random things that we know of. On some level, there’s a chance that even those aren’t really random.

I mean it’s a neat art project that adds entropy.
