Media Convertors - CAT6 to COAX to CAT6

I wasn't exactly sure which forum would be appropriate for this question.

At one of my sites (personal residence), I'm not going to have the ability to run new CAT6 everywhere due to the amount of remodeling it would create inside the owners home. It was suggested to me that we could use media convertors and utilize the existing coax runs. Media convertors near the camera mount to convert from CAT6 to COAX, and another in the NVR room converting from COAX back to CAT6.

My question is two fold.

1. What kind of quality can I expect to see on the NVR recordings using this method? If I have a 3MP / 5MP camera am I going to get that full quality at the NVR once all the media conversion is done.

2. Could anyone recommend some quality media convertors for this purpose?

- Thanks

People use this setup to get runs longer than 100m at full speed, actually this one can go 500m and some use it to avoid re-cabling. Why not just use the coax to pull new Ethernet cable? Just did that on a fairly long underground run, use the coax to pull Cat6.

I have thought about that, but we're worried that during the pulls in the homes walls we'd lose the cat6. =\

Do these come 1 or 2 to a package? It would make sense that you'd need 2, unless I'm missing something. =\

It's a package with a pair of the devices. This is from the attached PDF - AXIS T8640 comprises AXIS T8641 Ethernet over Coax Base Unit PoE+ and AXIS T8642 Ethernet over Coax Device
Unit PoE+. If you need help ordering it, contact WrightwoodSurveillance.com, they are an authorized Axis partner.

I have a set of MoCA boxes. These are basically 100mbps over COAX. They work well, and I imaging that for a camera setup they would be fine. With over ~150ft run I was getting 130mbps total TX/RX bandwidth, and 80 or 85mpbs in a single direction. I think for just running some IP cams they would be great unless your streaming a lot of cameras.

I actually just replaced them with a CAT6 run only because I bought them before I decided to put in my cameras and I needed to run all my cameras across that single link, along with my HDTV mpeg2 stream (~30mbps+). I figured it was better at that point to pull the cable in my house cause i was going to have to do the camera wiring anyway. It was a lot of work, but worth it.

The only negative is that my cable company refused to activate a second line for me for the endpoint jack. I do not have cable TV, only high-speed internet. I got around this by joining two unused coax lines in my external box, and then routing my network to a different "input" jack (different from what my cable modem is on). If you are going to use these on active cable lines, then you definitely need to check with your cable company, as your signal can back-feed into your neighbours houses.

Get the dualcomm adapters on amazon. They work like a champ but are $100 a set

Sorry, should have mentioned that the coax has BNC connectors on them for the existing analog cameras. We'd be using the BNC connectors, but replacing the cameras with newer IP based cameras.

I just use a small adapter on the dualcomm adapters

Do you guys love the Dualcomm the best for Ethernet over Coax? Have you guys tried these?

^Pretty neat, ethernet and power over coax.

One thing I find funny though is if all you can get to is a small hole where the old camera is how are you supposed to get that converter up there unless you mount another junction box.

Have anyone used the PoE-over-Coax from Dualcomm/Pairtek? This one can pass PoE power too.

it would cost you less to run a new ethernet line.
You can also use dahua epoe cameras and switches or nvrs

Yes

I use these for long runs.

These work great and way easier than all the nonsense you read in other threads about using fibre optic / solar / AC power for distant points where you need access points / IPCs / Intercoms / Door bells / controllers (example - entry gates).

Quality RG-6 is dirt cheap and I would trust an RG-G cable that has been through a 600' or 700' conduit pull long before I would trust a cat 5e/6 that has been pulled through a 300' conduit with 3 or 4 sweeps.

Thanks. That's good to know.
