If I already have an IP-based system, why would I want to upgrade to HDcctv?
HD DVRs are generally designed to accept not only HD camera inputs but also inputs from SD cameras and IP cameras (including megapixel IP cameras). Therefore, you do not necessarily lose any capabilities upgrading to HDcctv.
HDcctv is attractive to achieve (or re-gain) the ability to control Speed Domes using a joystick.
