but a detriment to those selling IP.

It's been my experience Hikvision TVI cameras require more power than conventional analog. I assisted a dealer with an installation and we got around 650' using a new (if I recollect correctly) 24VAC PS in the closet with the recorder. (18 awg power cable). Excellent picture quality compared to what they had before. I am curious how a coax typically at 20 awg center conductor would perform. Has Hikvision redesigned their TVI to require less power?
IP is here to stay but there is a market for TVI and it is an affordable alternative for some.

Last year TVI was at the IFSEC London together with FUHO and they promote a system called CCHDTV wich had power over coax R59. CCHDTV didn't make it so I think they are trying use is for something else. What I can remember they could send an HDTV signal and power (between 12 and 48 vdc 2amp max) over 300 meters with an signal damping loss of -39db.

Not sure what the real benefit is. HD is touted as a competitive upgrade alternative to IP, particularly if you already have existing coax. As long as the cable is viable, why would anyone bother to re-pull existing coax? Doesn't that add to the overall cost of the job = eliminating the benefit of using HD in the first place?
I do realize that there are many that sell HD for new installs. I just think there is some intellectual dishonesty going on..just a tad anyway.

POE switches typically cost significantly more than non for the same number of ports. Although you mention that the price of powered TVI is unknown, do you think the power supply cost can be avoided altogether?
One other small benefit: Manufacturers could add remote power on/off cycle capability

The HDcctv alliance has long claimed this was coming in the next version. Any comment from the Dahua machine on their plans?
Also, you might want to ask them, "WHAT HAVE YOU DONE WITH TODD?"

Many years ago, Power over Coax was sold and discarded on standard NTSC.
Maybe it's because there won't be an official standard committee, maybe because the guys installing HDOC really just want it to be CCTV but better.
IMHO I could actually see this more in the Costco stuff for homeowners, like the old Philips kits and such with all in a single quad wire.

Update: Both Dahua and Hikvision are claiming to support Power over Coax. However, both have stated projected time frame for release is later in 2017.

Could one use UTP Cable, Baluns and remaining unused conductors to transport power instead of coax? I've used "PoE Power Over Ethernet Injector Splitter Cable Kit" for Non POE IP Cameras that transfers power over unused pair(s), so perhaps use these w/ baluns?
If you could do this, it would be less then coax.

Here we are in 2018 and I still don't see a product from Dahua that offers PoC, other than their baluns, which max out at 1080p.
