Query: Great addition

The additional camera is a great addition. It allows us to monitor our 15 month old in her room and our newborn in our room. My only complaint is the interference when the monitor is near any other kind of wireless device. Other than that we are so happy we didn't have to go out and buy an entirely new monitor set. It was as easy as plugging in the second camera!
