Need help replacing Samsung DVR with RJ-45 cameras.

I don't know terribly much about CCTV systems but I'm pretty handy with computers so I'm hoping that skill would come in useful here.

 

Anyway I have a Samsung SDE-4002N CCTV system in which the DVR has kicked the bucket. http://www.samsungsv.com/Product/Detail/53/Samsung-SDE-4002N-8-Channel-DVR-Security-System

 

It uses UTP/RJ-45 cameras, and I would like to know what my replacement options are or do I have to get another Samsung DVR. From my limited research, it seems I might be able to get away with a bunch of BNC Baluns and any regular DVR should work. Is that likely to be correct? Is the wiring a standard thing or is it possible that the Samsung cameras are wired in a different way?

 

Basically, would I need one of these for each of the cameras? http://www.cctvsecuritypros.com/pavibawipo2r.html

 

As far as the specific problem with the Samsung DVR, it's keeps throwing a "HDD not installed" error message. The drive has already been replaced once, and it worked for a while but then started showing the error again. I put the hard drive in my PC and can find absolutely nothing wrong with it. No bad sectors or SMART errors. I can read all the files with no problem. To be honest I never even tested the first HDD, I just assumed it was dead and tossed it. It probably was just fine. I reset the unit to factory settings and it worked for a while, but it's back to the same problem. No amount of resetting is working this time.

 

Thanks for any help!

Go to resourse download. Download the user manual in ZIP format, uncompress. Open the manual, go to page 14.

 

Here you can see the connection it uses for the RJ45 connectors. You will need to either find baluns that use the exact same wiring diagrams (I think it won't be easy), or do the connections yourself. If you are able to get the cameras working, then you might go ahead and use any brand DVR.

 

You could even use the current DVR to power the cameras, and just take out the 2 video cables from the UTP cable, use an external balun, and use another DVR to record. So the old non working DVR would be there just acting as a power supply for the cameras.

 

It might get messy. If the system is very old, it might be worth to just reuse the existing cable, and get a new system from scratch.

Yeah it seems that it's totally different. Well that's a bummer. I did end up finding these:

Which appears to be baluns made specifically for this purpose. I'm going to contact Roxsat to verify.

In a last ditch effort to save this unit I tried switching the SATA cable. There was an odd lump in it which makes me think that maybe it was a faulty cable all along. So far it seems to be working again. If it craps out again then I'll probably look to replacement.
