One of the primary reasons Dahua dealers tell us they use ePoE, beside the obvious operating length extension and reuse of existing coax, is to avoid installing CCTV equipment into end users' IT closets. They wish to avoid finger pointing if something is unplugged, or drags down UPS availability, for example.
As regards the proprietary nature of ePoE, the Dahua LR-1002 EC/ET ePoE adaptors allow any third-party IP cameras to utilize long runs of coax.
As new Dahua cameras are introduced, they are equipped for ePoE, as well as standard IP operation, at no additional cost.
I just scanned through it briefly again and did not notice. Care to share one or two? I would not normally ask but since you brought it up, I am assuming you noticed many errors.
Just wondering if you tested the LR1002-EC/ET models with standard PoE switches and cameras? I ask as the manual for these units states that it supports non-ePoE devices and can also be used in conjunction with the LR1002 units to allow connection of ePoE cameras to non-ePoE.
With regard to the statement "ePoE camera selection is limited, mostly fixed lens, and mostly lacking advanced features such as super low light capability or Dahua's top end WDR..." a quick look at the Dahua website shows a broad range of mid and high end models supporting ePoE. All the models ending in -E or -ZE etc are ePoE models. I wasn't able to find any Panoramic or PTZ camera options with ePoE support so there's some room for improvement there but in theory you could use an LR1002-1ET at the camera end and an LR1002 at the ePoE NVR end.
We tested with standard PoE cameras, but I just saw what you are pointing out as far as using the LR1002 at one end and the EC/ET at the other. We will test that this morning and add here.
As far as model selection, I agree that there are quite a few models, but most of the Ultra series (their high end) does not show support. I don't think it's a critical issue, as most people using Dahua are likely looking at the Pro/Lite series for most installs. But it is a limitation.
We did some additional testing on this after the comments about third party cameras and switches working, and have edited the report. The net/net is that it does work, but it wasn't consistent in our tests. While the majority worked with no issues, we had several cameras which simply did not work, with no real rhyme or reason as to why.

Is there any other option here besides Dahua who can convert coax to IP effectively and efficiently?
We are having issues with using Dahua with our Milestone XProtect systems due to the fact that they do not allow downgrading of firmware. And if there are support issues that Milestone has to investigate, then Milestone will not support us unless we have their latest tested firmware installed on the camera.
Raymond, we have an Ethernet over Coax shootout from a few years ago. It's dated, but honestly, a lot of those manufacturers are still selling the same product. It's not a super fast moving market.
Are you looking for produce like Dahua's ePoE where the capability is built into the camera and recorder? Or is a separate transceiver okay?

Could you please hire an editor? Grammar and spelling mistakes just take away from the professionalism

We know of customers that sent back the Dahua eoc adapters as they burn down by very high percentages.

You should be able to use any camera with an LR1002. We have used them with Axis for example.
