Monitor for 2 rooms

Heather

I need monitor recommendations. We currently have a summer unfant in view 2.0 video monitor. I love it but it has never connected 2 cameras like its supposed to. I will have a 20 month old and a newborn in separate rooms. I'd like video and I'd like for it to tune to a room that has crying/noise in it. If you have the one I already have does it pair 2 okay for you? Maybe our actual camera is bad?
