mattmbr2005 0 Posted July 25, 2013 Hello all I am looking at upgrading the DVR's on a site to the newer samsung SRD-1673D DVR's. The site already has several SPD-2700 domes. I've been told I need to change the controller to Samsung's 6000 series controller to control the new DVR's properly. However, someone has told me that the older SPD-2700 domes wont work with the new DVR's.... I can't see how this is... surely so long as the settings are correct it will work ?! Surely any PTZ that supports RS-485 will work ?! Can someone please help! Matt Share this post Link to post Share on other sites
