ELI5: How did the cameras that were used during the moon landing work? How were they able to broadcast relatively clear picture and sound from space, using 1960s technology?

I ask this because there is a group of people who think the moon landing *itself* is real but the tv broadcast was staged. I personally don't believe that the broadcast was fake, but the question piqued my curiosity and I would like to know how it worked.

Basically, the important thing in space communications is not the size or power of the transmitter, but the sensitivity of the receiver. Once you have compensated for local issues like atmosphere, other radio sources, the rotation and revolution of the Earth, etc, then the only thing that affects the transmission is distance, and we have lots of distributed, really sensitive receivers to pick up weak signals.
