Clevergirl 0 Posted January 22, 2015 Hello, I have bought the QVIS Atlantis dvr 4 channel dvr and have had it a while. I want to upgrade and get an 8 channel DVR. Can I buy the additional video card and slot it into my existing DVR? If so, what should I be searching for? Share this post Link to post Share on other sites
