vector18 1 Posted July 29, 2012 A friend of mine wants to upgrade his existing 10 year old system installed by someone else. There are siamese coax run to each camera and replacing the coax with cat5 is not an option as they were run while the walls were open. Anyway, we want to upgrade to megapixel cameras with HD-sdi cameras and an hd-sdi dvr. Does everyone agree this is our best option. I know they also have IP baluns that convert IP cameras to work through coax, but they are around 80.00 a pair and we are upgrading 8 cameras. So, does anyone have experience with hd-sdi cameras, and if so, which ones do you recommend for outdoor low light use? Also, besides dahua, are there any other reasonable hd-sdi dvr's that work with PSS? Thanks in advance. Share this post Link to post Share on other sites
