Camera setups

OK guys, serious stuff now... as I'm finishing up the build I have decided I want to investigate adding interior cameras to capture the fun from three or four angles. Now I have a GoPro, and another HD helmet cam etc, but
I am trying to find an inexpensive HD camera that will shoot well indoors in low light. I need three or four, that will be located in the same room, and I want them to display on TV and/or PC, preferably selectable and tiled (by remote would be even better). I plan to mount them in my 737 simulator to record and view HD video from multiple angles and display in another room. This is a hobby for me, so I'm not looking for a pro install, but an inexpensive solution. Any ideas?
