It's closed-circuit TV (CCTV). You have a camera, mounted and focused to capture a scene, and the signal and control wires connect it to a control point. Every convenience store has remote closed-circuit TV cameras. This technology is quite old. The only new twist has been the advancement in camera design so that they are now very small.
Another example that can be seen readily are the camera shots from the upper stage of a launch vehicle, looking back at the first stage separating at the end of burn. SpaceX posts those shots fairly often. There is obviously no one on board holding a camera for those shots. Here is a quick example of the CCTV images from a Falcon 9 launch. The stage separation occurs about 2:38 on the timeline. https://www.space.com/spacex-launch-doubleheader-march-2023
I don't know exactly where the first camera was placed, but if you examine images of the LEM, you will find there are plenty of places where the body protrudes out far enough to view the exit hatch. Aldrin had to install a camera on a jutting mount, but that was the second camera.
No problem. I do ask questions because it just didn't make sense. Those are good answers.
No, I have no idea about remote cameras. How does that work?

Thanks for the info. I figured back then they will need some long mechanical arm in order to do that but I did not see that long arm
