The monitor screen can be turned off and audio continue to go at night. The unit is easy to setup and takes as little as 5 minutes to complete. It is plug and play. It is already synched and has clear and crisp video quality. The audio allows for individual to hear even a whisper. The unit does has an audio indicator that shows the levels of the audio. The unit is lightweight and the stand does a great job of keeping the camera in place. So the only issue I have with the unit is the lullabies quality and chooses. Overall, this is an excellent baby monitor that has quality audio and video.
