This is a Nuk 550VD video baby monitor. It has an eco mode which will mean there is no high frequency radiation in baby’s room. It can be used for audio or visual surveillance or both and the camera has night vision so it can be used at night even when it is pitch black in the baby’s room as you will still be able to see them. It has lullabies and natural sounds on it that you can play to soothe the baby if they wake up or to get them off to sleep and there is a timer, shuffle or loop on them so you can decide how long they play for. There is also a nightlight with a timer so you can give them light until they go to sleep.
