Query: Second camera for second child

We purchased a second camera to keep eyes on our second child. After he was born we hooked up the second camera, and it immediately started interfering with the first camera. Both channels now have lots of static and the screen will show the image for a second, and then go black. Our house is only 1700 sq feet so distance should not be an issue. We expected both channels to be just as clear as it was when we only used one camera, but we're very disapointed. We LOVED our Summer Infant Video monitor before trying to add a second camera. Customer support at Summer was very nice, but not very helpful.
