Query: Lots of background noise.

We had no idea which monitor to register for & picked this one b/c it had two receivers and was reasonably priced. It always has static and background noise (including our neigbors! but I'm told a lot of monitors do that), so the red light is always on. My son is still sleeping in our room so we hardley use it, but for my own piece of mind, we'll probably buy another monitor when he goes into his room. One that doesn't have so much background noise and static.
