We just purchased this system to replace our old analog cctv cameras from Geovision. I just have to say, I was very impressed with the video quality. We DID NOT have to replace our OLD cctv cables, we just used the same cables from the old cameras and the cameras came back with 1080p resolution. HD quality over our existing cables. We have other businesses that we are going to upgrade with and HD SDI is definitely the way to go. No need for IP configuration, just replace our old cameras and dvr and you are all set! Thanks again for the support Dave!
