Color is poor. A lot of noise (in a well lit room) for what i thought was an ok camera.
I have a Sony SSCE473
The camera is being powered by a class 2 transformer : MGT2420
I think part of the problem might be that I am running the video and power through a 100' combined cable. Then I have it split into 2 RCAs running one to each TV. 130 feet to travel is that too much? Any advice that isnt too expensive would be great. Thanks in advance.

Also do I need to adjust V phase and Level? I am going to go try and find out what those do...

I've used many of these with great images, no problems.
What type of cable "100' combined cable" are you referring to?

V Phase will have no effect on your picture. It is just for use when you are trying to synchronize two cameras.
Level is for use with an auto-iris lens. It is used to adjust the iris opening. It will have no effect if you are using a manual iris lens.
You can not "split" composite video signals and that may be the source of your problem. To feed video to multiple monitors and/or recorders, you must use a Distribution Amp or an RF Modulator.

Thanks for the response.
Now that there is natural light coming into the room the colors look a lot better then last night.
I have a fujinon auto iris lens.
You said, "you can not split composite video"
I have the RCA "Y" adapter. Do you think that is my problem?
What is the best way to hook the camera up to two TVs?
Does the 100 foot combined cable cause any noticeable loss?
Thanks

Swann 100ft/30m BNC to BNC Cable with DC Power Cable : SW271-S30
I bought it at frys for $30 bucks. I cut the ends off the power cable so i could hook it up to this camera and the power supply.

Just add a Distribution Amplifier and you'll be good to go.

Do you think a distributor amp will make that big of a difference? If I switched the 100 foot cable for a 10 foot cable with separate power would that help? thanks

There is no problem with the cable.
Yes a amp will make a big difference. The problem you're experiencing results mainly from low signal.
I've split video feeds with standard splitters and had no problems in some cases.

This setup is for a baby monitor. Living room then baby room then master. Maybe 15-20 feet.
The only reason I bought the 100 foot if for later use we are going to move soon. So I could bypass it with a 5 foot RCA then "Y Split" into the 30' RCAs that go to each room.

See if any of the TV's have a video out.

Well I have tried a few things including buying Distribution amp from radio shack.
The thing that helped the most was bypassing the 100' combined power and video cable. I still have the power running through the cable just not the video. I basically took off 95 feet of cable.
The distribution amp helped as well but not nearly as much.
Now I need to figure out the best settings for this camera?????
Still trying to decided if a 50 dollar distributor amp is worth it.

I think together you've hit on the problem: splitting the signal *combined with* the (somewhat) long run. I've split signals many times, with only minor drops in picture level.
Another part of the equation might be the TYPE of coax you're using - RG/59, RG/6, RG/58, or otherwise. I'm assuming by "combined power and video" you're referring to either "siamese" cable (separate coax and 18/2 wires connected by a web) or "bundled" coax/power where both run inside a common sheath, as is often provided with cheap cameras?
Either way, the fact that power and video are "combined" in one run is probably irrelevant. The cable impedance, factored with the length of the run, AND with the splitting, is what's really giving you headaches.
