Query: Don't waste your money on a second camera!!

A second camera does not work the way you will want it to work. The two cameras cause interference with each other as you switch back and forth between the two cameras. The picture has wavy lines, and the sound is choppy. I wrote Summer Infant about my problem, and they do not want to do anything about it. They said that the cameras operate on a 900Mhz frequency, and could cause interference with each other. So I am thinking to myself: Then why do they offer a seperate camera so you can monitor two seperate channels? Easy, it's to sucker you into buying another one only to find out it won't work!! Another fine example of little ol' working class man versus big greedy rich corporate america. Also, it took 3 pestering e-mails to finally get an answer out of Summer Infant.
