With the Philips AVENT SCD570 you won't miss a single sound from the baby room. The DECT technology of the SCD570 ensures that the sound can be heard crystal-clear by the parent unit. Turning the baby monitor's sound up or down can easily be done with the volume button, but you can also filter according to the different sensitivity levels. When it's time for a little nap, it's possible to remotely let your baby hear a lullaby, or turn on the night light for some extra reassurance. Is your baby sleeping peacefully and would you almost forget that it is his feeding time? You will not forget this with the Philips AVENT SCD570. The timer function assists you with this.A baby monitor with battery is like a smartphone that runs empty when you are playing a movie. The battery life is limited.
