Need help with installing 3rd callup monitor

[CakeSalami 0]

Hi all,

 

I currently work retail loss prevention, and am looking to set up a third call up monitor as we already have two. We received a third keyboard in the mail from our corporate office, with no instruction, and them saying it needs to be setup. I had little to no experience with any of the equipment, but after spending my whole shift yesterday attempting to set it up, I got close, but am stuck currently.

 

Our current setup consists of 4 Ganz 1TB DVRs, a Mega Power 3200 CPU "box" (not sure of the correct terminology), and ~150 cameras, 16 PTZ's.

 

I have the keyboard setup and working correctly, after finding out I needed to connect the RJ-45 to the jumper, and then to the "brain" on top of the box (again, sorry for the terminology). But, my issues seems to be actually setting up the monitor itself.

 

For our first two callups (they were installed long before any of the current team being there) it seems to have a 3 way coax splitter; one of the "ins" attaching to the DVR, one of the "ins" attaching to the monitor itself via spliced Yellow VGA video adapter, and the "out" attaching to the respective monitor slot on the "box". So, I attempted to follow this info. Using what we had at our disposal, my coworker and I took a line of naked coax cable and spliced respective adapters to each end of the cables and used an extra splitter we had lying around to do so (although I can guarantee it wasn't the best way or the most orthodox). Well, the video did feed and worked, however, the splitter itself had a switch on it, changing between cable and antenna, which would obviously cause either the monitor or DVR to lose signal. I had an easy solution! I work in a store, I'll just store use a splitter off of the shelf.

 

When I came back to attach it as the other two monitors were attached, it didn't work. No signal, nothing. A little frustrated, we tried using the old switch splitter again... and nothing. no signal again. So it must be how we had spliced the adapters using the coax cable... correct?

 

At this point I had stayed two hours over my shift end and got frustrated and packed it up and left. I'm looking for alittle guidance on what I maybe did wrong so I could get this up and running asap. Thank you very much for any and all help!
