Older building with COAX runs

Hi, I have an older building with coax runs to all previous cameras. We are looking to upgrade the system as remote access is no longer working for us. I'm searching for a Dahua NVR that accepts BNC connections? Or possibly a switch of some type that would be able to send power to the cameras and convert them to ethernet. We have Dahua systems in place and it's already been decided that we will be sticking with them. I'm entry level, have set up a few buildings so far with existing cat5 run to all camera drops, not quite sure which equipment to purchase in order to get these cameras online.

Any tips would be greatly appreciated!

Are you saying you have Dahua analog cameras in place now and you are planning on keeping them and just need an NVR (XVR actually) to connect them to and manage them?

Or are you looking to replace all of the analog cams with IP cams?

Looking to replace all analog cams with IP. COAX run through the building already to 15 camera drops, owner of the company is dead set on using Dahua as we have about 30 properties with cameras and one p2p app for viewing is desired. Will either need to convert from digital to analog and back, or pick up an analog cam that can plug into a typical dahua NVR. I realize that quality will not be as great as my other buildings, but some view is still better than the current no view. Current system is GANZ, which "worked" in the past but did not allow for remote viewing of past video, which is what most of my management staff want.

Are these MoCA devices? There is a standard for networking over coax... If interested, see here:

MoCA Alliance

FWIW, the OP will need to power the new IP cameras (POE recommended) and I believe MoCA has provisions for data-only.
The Empire Tech / Linovision devices that wittaj linked provide data + POE over coax. :cool:
 
If you want to switch to all IP cameras you will need a new NVR, and all new cameras.
empiretech01.com

EmpireTech NVR16CH-16P-2AI 16 Channels 1U 16PoE 2HDD Network Video Rec

Multiple decoding formats Support AcuPick with Max. 16-Channel Support N+M cluster AI by recorder AI by camera Security baseline 2.3
empiretech01.com empiretech01.com

So figure $400 for NVR plus approx $200 for each camera
And you will have to either pull new cable or use the converters, adding $70 to each camera



If you stay with analog cameras it will be much cheaper
I ran a Dahua XVR for a long time.
This XVR can accept both IP and analog cam inputs

And you can get reasonable quality image from the better analog cams. Their 4K cams are quite good

These are older 2MP and 4MP samples. Their 4K cams are much better

This is very helpful! thank you! Interestingly enough, they just scrapped this camera rework and are going with an outside contractor who is charging us 5x cost of materials plus labor eyeroll. Never understand paying someone else when we can do the work ourselves.

If the current system is coax, there already Power at the camera end, but it's 12VDC. Usually via a Siamese cable ( dual cable with coax and 12v). If the project had gone forward, POE wouldn't be an issue, just ethernet to Coax conversion. like the The device @wittaj showed. Also a Passive conve4ter would work if you use the 12VDC already at the cam location.
