PatMcD 0 Posted August 2, 2011 I need to add a PTZ came in place of a fixed camera to a DM Sprite 2 DVR. There are already a couple of Kalatel PTZ's on the system. The PTZ's were installed about four years ago. I was told to beware of potential problems because of protocol modifications by DM over time. Has anyone run into this? If so, how does one avoid issues if there are any? Share this post Link to post Share on other sites
