There is no interference it just stops working

Video quality day and night are the only reason this review gets 3 stars

however, the sound on mine only worked half the time, it came down to the point to where the way i figured out my baby was crying was i heard him 3 rooms away and not a single peep from the monitor

However, the camera and the handset have major connectivity issues

I think once my little girl is bigger and in her own bed/able to walk I will appreciate the control of the camera from the parent unit even more! Battery life is always an issue with monitors it seems but as long as you have a plug in you should be all set

Great features with a few glaring weaknesses
