Connector Types/Sizes Charts?

There are no doubt hundreds of different types of jacks, connectors, plugs and sockets, but are there any charts per category to be found? Anybody have a source? It would be nice to have a reference.

Ex: The back of a CCTV camera PCB board…

What is that? And what size, etc. of “that” is it?

Sincerely,
