How did a TV recording studio broadcast live television via a film camera before the use of video in 1952?

Video cameras had been around for two decades by 1952 so live broadcasts used video rather than film. Recording video was rather harder because video recorders were not available until the mid 1950s.
To capture content for broadcast later demanded that film was used. The film was then run through a tele-cine unit. It is similar to a film projector but had a video camera mounted in front of the specially made lens. The film was played in sync with the the television frame timing and each film frame was converted to video.
Tele-cine equipment is still in use today and although they are far more sophisticated, they work on exactly the same principle as the early units.

How does a security camera work?
A security camera works through a closed circuit broadcast. Where a TV signal is broadcast openly, a closed circuit camera is broadcast only to a specific place. Basically, the security camera broadcasts a feed, just like a normal camera. That feed is only sent to one place, usually inside the same building as the camera, which then displays that image on a monitor or host of monitors.

How long have movies been shot in high definition?
Most movies are shot on film and not captured to video. Because of that, they have never suffered from the constraints of television resolutions. Typically, 35mm and 70mm film have an effective resolution that is higher than either SD or HD television. When a movie is broadcast, it is converted to a video signal using a tele-cine unit (a film projector and television camera combined into a single device). The television resolution is defined by the camera in the tele-cine unit at the time it is captured to video. so, film that has been shot before the days of HD television can still be broadcast as HD.
Why did Apollo 12 plan fall through to broadcast color TV?

What is the differences of cctv and ip camera?
CCTV means closed circuit television. It refers to any television system that is not broadcast to a large number of viewers. Traditionally, CCTV meant one or more cameras, one or more displays and sometimes, a recording device within a building or a small group of buildings. Generally each video feed used a single co-axial cable. An IP camera uses a network (Internet Protocol) to deliver a signal from one point to another. They are being used increasingly within CCTV systems as they overcome some of the limitations of standard cameras such as video transmission distance. The use of low cost network cable provides another useful benefit. An IP based video signal can easily be manipulated, stored and transmitted to other locations and allows CCTV to be monitored from remote locations with ease. IP is also used for broadcast applications, so an IP camera does not always mean it's a CCTV camera. View IP Camera and CCTV camera from t.co/1tqbO25qLV There are obvious difference in parametres.
