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".
I am describing systems my company interacts with daily. And yes, you
are "wrong".
You are talking about what you are involved in and I am talking about
what I am involved in.
From my perspective it is YOU that is wrong.
Just because you don't know what you're talking about doesn't make you
right.
I know very well what I am talking about because I am intimately involved in
it.
Your basic problem is that you feel only the things YOU are involved with
are "correct" or "right" and can not seem to understand that the Universe
does NOT revolve around you and your experiences.

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.
Again, wrong.
Nope, it is exactly what is happening with the systems I am involved in.
Obviously you are wrong.
See above.
See above.

Your experience and situation may be different.
They definitely are. We are in the commercial business.
I am not.
Then you have very little experience from which to speak. How many
installations do you do a year?
I don't do the installations, there are big teams to do the grunt work, and
it depends on how you define "installation".
The total number of cameras is currently somewhere around 1,000.
Here'a clue; the 2014 budget for the sub-organization I deal with is $21.1 B.
Yes, that is a 'B'.
So what? It doesn't mean you have any idea what you are talking about.
Just that your sub-organization wastes a lot of money.
And you know that how?
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.
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.
What part of "miles" is it you fail to understand?
Pray tell us, oh great magician. How do you get analog cameras to go
"miles" over coax without all kinds of amplifiers on the way? Make and
model of the cameras and coax.
Of course there are amplifiers in the system.
How else would you get analog video from a camera 25 miles away?
And of course there is more than just miles of of video cable and the
stuff to get the video to go for miles.
Again, exactly what?
It is not my job to specify the nuts and bolts out there nor do I care in
the slightest as it is someone else's job to make sure the video gets to
where it is supposed to go.
There is also miles of the multidrop, 1200 baud twisted pair copper for PTZ.
Again - exactly what PTZ cameras will run off of 1200 baud twisted pair?
Make and model of the cameras and the controllers.
The original cameras were Javelin JO505R/D12 and PTZ control is via a
custom program written on HP-UX Unix.
As Javelin is long out of business, newer models from Pelco and Cohu have
been added to the mix and the control program updated for the newer models.
As new contruction adds TCP/IP connected cameras over fiber, the program
has also been modified to allow TCP PTZ control in addition to legacy
serial.
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).
That would be about the time frame of the first installed camera.
When the replacement costs are in the hundreds of millions of dollars
and the system runs 24/7/365 you don't replace everything just to have
the latest technology; you update through slow and carefully planed
attrition.
And when you have no idea what you're talking about, you can make any
claims you want. That doesn't mean you are right. In fact, from this
post you show just how ignorant you are.
From your posts you show you are a self centered egotist who is unable
to understand that the whole Universe does not revolve arout you.
You are firmly convinced that the only person in the Universe that does
things "correctly" is you and can't possibly understand there may be other
situations where your "solution" doesn't work.
