I am currently working on a project where my customer wants to control his 3 Panasonic PTZ cameras through a 3rd party DVR (Honeywell Fusion). His is currently doing this with an older Panasonic Matrix Switcher, which he wants to eliminate. The problem is, they are using up-the-coax for the PTZ control, which the Fusion cannot. I've found the WJ-MP204C, which looks like it will work (the Fusion lists Panasonic protocol), but I've heard mixed things from both Panasonic and from other integrators. Has anyone used the MP204C in this manner? The model number for the cameras, if it helps, is WV-CS845B.
