sorry for the missing specs of my diagram.
1. i'll be using CAT5e/CAT6 4pair UTP cables from the camera to the DVR.
2. 14" PC monitors with VGA or DVI
3. 4 channel AVtech DVR
4. Passive Baluns
Types of baluns and camera connections aren't relevant to the plan (at least as you've drawn it)... only the signal coming out of the DVR.
i want to view only one camera per monitor but i also want to use only one DVR. can the signal coming from the DVR vga output be split to each monitor?
Yes, but both monitors will get the same display.
Other options are to use a spot output (if the DVR has it) to feed the second monitor a different view... or as Paulson suggests, just split the camera's feed out to the TV (although that won't allow you to change which camera you're viewing).
