Here is a chat transcript that we recently had with one of our customers regarding a multiple surveillance monitor setup:
Customer: I would like to play 3 out of the 8 cameras I have onto the TV in my lobby. Can you tell me how I would go about doing that? Currently I have 16 BNC Video Inputs, 2 BNC Video Output and 1 VGA.
Customer Support: Usually VGA is used for the main monitor connected to the DVR. If 1 of the 2 BNC video outputs is labeled as "spot monitor", this will allow you to select channels you wish to display in the lobby.
Customer: None of them are labeled as spot from what I can see. Can you tell me what I would need to order please.
Customer Support: Most likely one of them is so you just need a BNC cable – http://www.cctvcamerapros.com/BNC-Video-Jumper-Cables-s/260.htm
with a BNC to VGA Convertor – http://www.cctvcamerapros.com/BNC-TO-VGA-Converter-p/bnc-vga-converter.htm
and a VGA Monitor – http://www.cctvcamerapros.com/LCD-Surveillance-Monitor-p/mon-lcd19.htm
I believe this is the most affordable solution.
Customer: Would I be able to display it on the TV that I currently have in the lobby?
Customer Support: Most modern flat screen TVs have a VGA video input.
Customer: Ok being that I would like to display 3 of the cameras would I need more than one bnc/vga converter? Also I still need it to go to the DVR so would I need some kind of a splitter as well?
Customer Support: No, this is on the video output side. DVR spot monitor out to BNC to VGA Converter, then converter to TV.
Customer: So it would display all the cameras?
Customer Support: This is why you have to determine if either of those BNC outputs have spot monitor functionality. This allows you to select specific channels to display to a secondary monitor. Rather than just duplicating the entire main display.
