I purchased this about 5 years ago and used it for about a year. All accessories are included. I have confirmed that both the screen and audio are working. There is some discoloration on the plastic part of the camera, and there are minor scratches on the monitor, but there are no issues with use. From the time of purchase, I was told that the battery drains quickly, and I was advised to use the AC adapter. Therefore, I haven't used it wirelessly. Operation with the AC adapter is not a problem. I set up the camera in the bedroom on the second floor and was able to monitor it from the first floor. It's an older model, but it's still usable. How about it as a trial? *Please purchase only if you understand that this is a used item.
