Unisar BebeSounds TV984 Flat Panel Color Video & Sound Monitor

We bought 2 of these monitors - 1 for each child. The box says "No Interference from 2.4 GHz phones, wireless networks, or microwaves". The monitor works fine in the room next to the camera. But beyond that, we get reception ranging from ok to nothing....

We were excited about the big picture with this product but the product picks up so much interference that we have a 50\/50 chance of getting the picture to work.
