The BT Digital Audio Baby Monitor 400 gives you peace of mind whilst your baby is resting or sleeping peacefully. Never miss a sound with crystal clear interference-free digital HD sound (Hi-ds) so every breath, gurgle and cry from your baby will come through loud and clear when they need you. This unit also features sound-level LED lights for when you don’t want to hear every snuffle but want to be alerted. The wireless range of the monitor lets you keep connected to your baby up to 50 m indoors and up to 300 m outdoors, so you don’t miss a sound.
