The picture and audio quality are surprisingly good for a wireless system with a 1.5" display and reasonable price. The night vision setting works very well from 8 feet away. I have not tried further away than that. From that distance we can view the entire crib. The camera and receiver can work on 4 AA batteries each, or with the included AC adapters. We have a two story house older house and the camera is on the second story and we have the receiver on the first floor on the opposite end of the house and the reception is great. The "auto" mode is volume adjustable. This mode allows you to set a "cry" threshold that will activate the video, or the video can be on continuously.
The only interference problem I have is from the wireless router. If the 2.4 GHz router is on (not necessarily in use) it causes a line and static blurp about once per second. Unplugging the router causes complete noise-free operation (unless the microwave oven is in use). The 2.4 GHz cordless phones have no affect.
Sorry for the long review, but these are answers to some of the questions that I had before buying. If you were to ask if I would buy this same system again, I would answer "Yes." The quality seems excellent for the price.
