Ive got a vacation home that was pre-wired for cameras. The only problem is they ran Siamese RG59 instead of cat5 or 6. I’d love to pull new wire but it’s a flat roof with no attic acces to the trusses so new wiring would mean lots of holes. Plus it’s a VACATION home, so the last thing I want to do while I’m there is work. I’ve seen DECA’s and MOCA’s that might work. Anyone have expreience with that relating to cameras?
I’ve also seen some POE Ethernet over coax adapters. They are more expensive but that would be super simple.
Final option would be to drill through the roof, and run the cable across the top of the roof. It has parapet walls on the roof top so it would be easy to drill through from there to the other side of the parapet where the camera will be mounted. Any thoughts?

There are some really good non-IP cameras that will work with the coax. Somewhere on the forum a guy has some Dahua cameras with really good video, day and night.

that would be @bigredfish.

Dahua Starlight HDCVI cameras would be a good option.

If you simply have to stay with IP based, the adapters @fenderman points out may be the way to go.

Alternately as mentioned, I have a couple of systems using HDCVI cameras that rival most high end IP cams. Simple plug n play to your existing cabling with a Dahua DVR/XVR and extremely reliable and maintenance free. Up to 4K and recently introduced a full line of 4K Starlights which are pretty exciting, though I dont think theyre available quite yet.

I run the 2MP Starlights and am very satisfied with them. Here's a couple of examples of HDCVI Starlights.

Be sure and change the YT player to 1080p

Hi n8huntsman

I looked at baluns on Amazon for IP cameras over Coax - and they quickly started to add up.

The baluns for BNC / analog cameras over Cat6 were significantly more affordable.

Thus, I have really started to dislike house builders / installers who are still installing coax.

The adapters for dahua epoe are 14 via bandh.. likey less via China....not sure if you need a dahua epoe NVR or if they will work with a switch for standard distances....

Thanks, that's a LOT better than what I had seen so far...

Yes those are for standard ip cams... I have no idea how these work and if they require a dahua epoe camera and epoe nvr on both ends...

Good info guys!
I saw the ePOE, IPC-HDW5231R-ZE specifically, but was a little unsure on how they work. After more reading it makes more sense now. I assume these cameras will be on par with the IPC-HDW5231R-Z IP cams that I already have and love? I see it needs either an ePOE NVR or an ePOE switch. I assume that if I had an NVR5208-4KS2 I could simply use the ePOE switch on a single port of the NVR? Might be cleaner to get the ePOE NVR, just asking so I can compare cost of all my options.
I also want a PTZ, something comparable to my SD52C225U-HNI Looks like the selection for ePOE camera is limited at this point. May have to forgo the PTZ, at least for now.

Looking at the HDCVI route, Im surprised at the price and selection. I thought this technology was deprecated but I guess I was wrong. Would an HDCVI DVR support power over coax in some form or would I need a separate power supply to the cameras? What DVR would you recommend? Preferably something Andy sells to make shopping easy! Is there an HDCVI version of the above camera? Having trouble finding one with varifocal?

Are you suggesting there is a possibility that at standard distances a regular IP camera and regular POE NVR MIGHT work with those adapters? Is that $14 a piece or for the pair? For that price might be worth testing if there's a possibility.

I was really disappointed when I popped the plates and saw coax. It was built in '06 so I suppose back then it could have gone either way. Thinking back, it wasnt too long ago, 7 or 8 years, I built my outdoor bar/kitchen and ran a coax cable (for a Directv box) and never bothered to run cat6. Kicked myself about 6 months ago when I had to rerun cat6 over there, and I've never used the coax, not even once.

Possibly...buy I'm guessing it may require at least an epoe camera...I would ask Andy to confirm with dahua...

This one is varifocal: HAC-HDW2231R-Z-DP | Dahua Technology
HDCVI generally doesn't make sense when new cabling is being run, but there's enough existing coax to keep it around for a while.

HDCVI PTZ cameras may use RS-485 for PTZ control I think (additional cable required), so for that location you'd need to run a new cable or use some type of adapter with a PTZ.
You have siamese cable so you aren't limited to things that can provide power over coax. PTZs are power hungry anyway, often using a higher voltage. There are lots of power supplies available if you want to power over the siamese cable.

I believe the XVR5000 series is tailored to PoC but as @tangent said, you arent restricted to that.

The CVI equivalents to the two popular 2MP IP low light cams are the
HAC-HFW3231E-Z Vari-focal Bullet' (Also in Z-12 configuration for more zoom)
HAC-HDW2231R-Z Vari-focal Turret (DP=Dual power capable)

The new 4K Starlights have my mouth watering, but Pro/Ultra DVR/XVR support is still limited.....I'm not experienced enough to advise on CVI PTZ's but they do have matching models for many of the IP Starlight versions...

The 5000 series XVR/DVR (Lite series) which support 4K or the 7200 series (Pro series) and of course you can run IP cameras on them as well

I believe the cameras don't need the RS-485. They use UTC to control the PTZ via the DVR. You can but an UTC controller the goes inline.

I haven't used CVI PTZs, but I think you're right they can be controlled without a separate cable. They do have RS-485 connections. I'd probably choose an IP PTZ over a HDCVI one though and find a way to make it work.

Is there a decoder for these model numbers? HVCI vs XVR? AN vs A at the end for instance? What’s the main difference between 5204 and 7204, 15 vs 30 fps? I don’t see much difference on their site. What about 1U vs, smart, compact, mini? Just physical size?

I ordered a XVR7208A recorder, 6TB Purple drive, and a HAC-HDW2231R-Z camera and wall mount. Also got a Monoprice 16 channel 12vdc power supply, some BNC compression terminals, and power pigtails. Anything else I overlooked? I'm accustomed to IP cameras. Coax is foreign to me.

Thanks for all the recommendations above.
