I have three children, so I thought purchasing the extra monitor plus the extra camera would be a great idea.....not so, the first monitor works great solo. However, when I added the new monitor static was overwhelming. We placed this in many different locations in the room and still no luck. I tried just using the new monitor with the extra camera and the new monitor worked great....solo. When you add this additional camera get ready for massive static. I will be returning this item. Hope this helps.
