The one item in your list that no longer has any use!

I've got one of those, but not Heathkit, and PAL not NTSC

Closed Circuit TV is still mostly analog.

That's changing. We install much more digital (IP-based) systems than
analog, nowadays, including updating old analog systems.

Analog is still out there - but as the price of digital cameras comes
down, analog is fading.

Yes, new systems are predominantly digital, however there is a HUGE
installed base of analog no one is going to replace just because, though
some are replacing the recording/viewing portion with digitizers.

If you have to dig up and replace miles of cable to have digital cameras,
the cameras are likely to stay analog for a long time.

That's where you're wrong. Probably 1/3 of our installs is replacing
old analog systems with digital. The higher quality of a digital
picture is the main selling point, although the digital recording also
helps.

I am describing systems I personally know of and deal with, so no, I am
not "wrong".

Digital cameras are only installed for new construction and the quality
of the digital video is no better than the analog video as the analog
cameras were high quality video since day 1.

Your experience and situation may be different.

And BTW - we do it over the existing coax. No "miles of cable" are
replaced.

Such is not possible for many reasons in the systems I deal with, and
yes, there are literally hundreds of miles of cable.
