CD-1 Color Bar and Dot Generator

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.

But the monitors these days are LCD and not CRT.

The days of static convergence, dynamic convergence, pin cushion, etc
are gone.

The new ones likely are but the vast, already installed, base is not.

Essentially irrelevant; when checking out such a system about the only
thing that matters is a known, stable video of something.

Apparently you have never worked on a CCTV system; a known, stable, and
portable source of video is a handy thing to have when troubleshooting.

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.

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

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.

I am describing systems my company interacts with daily. And yes, you
are "wrong".

Again, wrong. As I indicated, probably 1/3 of our camera installations
are replacing analog cameras with digital ones. The number of analog
cameras we installed last year could be counted on both hands. Digital,
OTOH (including replacements) are a lot.

Your experience and situation may be different.


They definitely are. We are in the commercial business.

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

You are obviously not familiar with HDBASE-T - which is a recognized
standard, just like HDMI, and is supported by multiple manufacturers.
Depending on the manufacturer, it is quite easy to send up to 4 IP
cameras over one coax up to 1,500 ft. - farther than analog cameras will go.

And if you need more, there are any number of solutions - all over coax.

I don't know what you deal with - but it's obviously not the current
state of the art. Sounds like something out of the 1980's (or before).
