vitHoward 0 Posted May 14, 2005 An alternative to using coaxial cable is to use UTP, unshielded twisted pair with baluns. What the balun manufacturer's don't emphasize is that with the unpowered (passive) baluns, the color burst portion of the signal drops off rapidly. If we're going more than a couple of hundred feet to a digital recorder, then we're going to used a powered balun at the headend to insure that we have a good color signal. http://www.videoguardit.com/cctv_essentials.html Share this post Link to post Share on other sites

34Ford 0 Posted September 6, 2005 I need a couple of 100 ft. lengths of siamese coax and I considered buying the pre-made cables with the bnc's and barrel connectors made on them but almost every site I go to the pre-made cables dont appear to be Rg59 coax. Im afraid to buy them for fear they are not as good. Can this be true? Thanks, Dennis Share this post Link to post Share on other sites
rory 0 Posted September 6, 2005 They are most likely RG56 or something of that grade, stick to at least RG59, which itself isnt exactly that thick, but works good. Share this post Link to post Share on other sites
vitHoward 0 Posted September 6, 2005 The RG number refers to the size of the cable. More important is the contruction. Check my previous post. Hope this helps. Share this post Link to post Share on other sites
34Ford 0 Posted September 6, 2005 You know what, it just come to me that if I bought pre-made how in the h$#l would I pull all those connectors thru the walls. I believe my best choice would be to buy the coax and......then install the connectors. What was I thinking, duh. Share this post Link to post Share on other sites
cablejim 0 Posted October 10, 2005 Here's where I get all of my coaxial cable. http://cyberxlink.com/index.php/cPath/84_135 I usually stick with RG6 for CCTV, but occasionally I will use RG59. I have used both the siamese and the quad shield and I know they are great quality. Share this post Link to post Share on other sites
vitHoward 0 Posted October 11, 2005 Jim, I hate to burst your bubble, but quad shield cable is not the correct construction for composite video (the type of signal most CCTV cameras product). It is great for cable TV, but not for CCTV. Hope this helps. Howard Share this post Link to post Share on other sites
