This is a Campark baby monitor with a camera and audio function. You can hear and see baby easily and clearly on the 4.3 inch screen on the parent device. There is no wifi required so everything is private. The split screen function allows it to support two cameras at once if you want to buy a second camera to use in another room. It switches to night vision automatically when it is dark and the monitor camera will switch on when it detects sound so that you can see what is going on using the screen when they wake up. You can talk back through it to baby and play a lullaby so that you can soothe your child without always having to go into their room.
