Home surveillance help

Hello,

I would like to modulate video feeds from some door cameras such that they can be viewed on any tv in the house. I'm not sure of the best/correct equipment needed though. Any help the group can provide will be greatly appreciated.

Here is my current configuration. Open House wiring panel in the wiring closet.

2 Open House Channel Plus 532-230 RG6 Splitter/Combiner for TV distribution. 1 Eagle Aspen 3-in 4-out multiswitch. 2 LNB inputs used for satellite. 4 outputs direct to the TVs. The antenna input is not used.

2 home runs of RG6 to each tv. One run is used for DirecTv. Cat 5 run to the front door and both rear doors. RG6 and power run to an under eave location above the garage.

I am thinking about using the Open House H722 camera at each of the doors, since they accept Cat 5. Is the black and white version adequate for an entry, or should I get color? I'm not sure what type of camera to mount under the roof. It will be aimed at the entrance to the back yard. Any suggestions? Black/white or color?

For the Open House cameras, I think I need an Open House H512 modulator to convert from Cat 5 to video. Do I need one per camera? Space may be limited, so it would be nice to only need 1.

Assuming all of the above gets worked out, how do I combine the feeds from all 4 cameras such that they can be used as an input to either the antenna input on the multiswitch or the Channel Plus splitter/combiner?

Thanks for the help.
