Hello Baby HB6550 Video Baby Monitor allows you to check on your little one on a large 5-inch color screen. Soothe your baby with lullabies and soft sounds from the baby device. And, you can ensure your baby is comfortable by monitoring the baby's room temperature displayed on the LCD screen. Does the baby need you? Let them know you're on the road with a two-way intercom. Even during nap time, automatic night vision makes it easy to see what's going on in the crib without disturbing the little one's sleep. And, a built-in temperature sensor lets you know if it's too hot or too cold in the baby's room and sends an alert to the parent's unit.
