We've tested this camera and it DOES record crystal clear sound and video as well as play black video and audio. BUT IT ONLY WORKS DIRECTLY PLUGGED IN. I'm including a single battery and charger, but I cannot get the battery to hold a charge. The camera only works when plugged directly into a power outlet with the provided cord. This will be perfectly fine for someone who needs to use the camera to transfer or play old home videos. It's possible it will work cordless with a new battery, but I cannot guarantee that. Sold as is!
