I just found it is a CTRing Co Ltd from Korea. Anyone happen to know where I may find online manuals?

Thanks for your input I'll do some checking in that direction.

Here are a few shots of the interface. Hopefully this will help.

Sorry for the delay in getting these up here.

I was recently given a DVR that does not indicate the manufacturer. The model number is listed as MSDM 1648AV but I can not find any reference to this on the internet. I'm trying to find out who the manufacturer so I can get a manual to help with some of the set up. It is a 16 Channel DVR with 8 Channel Audio and 500 GB Hard Drive. If anyone knows where I might find more information or if you've heard of something similar I would be very greatful for your feedback!
