I am not sure who is getting their info from, whether from experience or from writing on the wall. Copy this link and read this article in Security Sales & Integration magazine, http://www.securitysales.com/article/hd-sdi-the-hidden-hd-technology, highlighting the overwhelming benefits of HD-SDI to IP or less res like CVI or AHD. Read from some of the best security experts in the industry why SDI is "hidden technology". It is true, the best copper coax is the best, preferably copper braided, but anything pre 2005 would most likely be in that category because the newer copper coated or aluminum coated copper is less than a perfect match for SDI. If you installed your analog system, and you used RG59 Siamese, you are most likely in luck. You can get a signal tester to test the video signal before going that route, a cheap investment for an expensive loss, unless you have to simply run new RG59 copper-copper-copper. If your runs are less than 150' you can run Cat6 with the media balun, but I would bet that your coax is fine, unless you are having video problems now from BNC connections or cable issues. Try switching cameras to different channels and see if there is any difference, or there can be many way to use the process of elimination. Bottom line, HD-SDI has been a 4:1 sales ration over analog in the last 6 months in our market. Once a customer wants a system, and is ready to invest, why not get the very best system available for the price, without setting up servers, switches, and having to "dumb" down cameras to get the best picture from loading up a server with "MEGADATA from MEGAPIXELS'? HD-SDI compresses to H.264 at DVR, not camera, and is transmitted in HD dual streaming live mode with our level 4 and 5 DVR's.
