The cam corder was not invented in 1972. You had to manually hook up to a reel to reel 1” tape or 3/4” tape recording machine... the size of a huge TV...
and that was if you had a power outlet to plug into, to power all that video technology.
And then, the transmitter would be huge.
But the battery pack would be the size of another huge Television set.
That said, the photos you posted are probably of black and white video cameras. Too small. The color tube(s) made the color video cameras larger.
Both needed to be plugged into the wall or TV studio power supply.
The official NASA story says their color video cameras were only 4 pounds in weight. That is dubious, too. They also said the relay time to transmit to earth was 1.5 seconds... nonsensical.
Apollo 11 did not.

The link that I gave you at #78 explains why the Apollo color camera did not need three imaging tubes.
