I have a couple of these for sale. Got them as part of a company bankruptcy sale, it was some type of security company. Anyway, I bought the lot, used 2 to build security DVR's out of a couple of 1U servers I had. Got Zoneminder to work with these and have not had a problem in over 6 months of using them.
Just do a search on ebay for KMC-4400R.
