Watching your baby is fun, but watching your baby on the large Alecto DVM-143 4.3-inch screen is even better. This video baby monitor produces a clear image of your little one, day and night. This way, you'll see exactly what your baby's up to. The many extra functions, such as the two-way audio, zoom function, lullabies, and temperature sensor make this a very complete baby monitor. Thanks to the included mounting materials, you can also mount the camera on the wall, so you'll always have your baby in view.A baby monitor with battery is like a smartphone that runs empty when you are playing a movie. The battery life is limited.
