zibnata 0 Posted October 25, 2012 Hello, I am trying to understand the difference between a bad, good or better DVR. A couple of years ago i started messing around with cctv at my home. i am an electrician so running wires etc. is easy for me. I bought cameras which I thought were pretty good but I am now upgrading to 700 tvl which are a huge improvement. Of course everyone that I know wants a system so I need technical help. below is a link of the DVR that I have. My questions are, is it any good ? If I wanted to upgrade then what should I look for ? thanks http://www.ebay.com/itm/170653443642?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649 Share this post Link to post Share on other sites
