Stay Connected, Even in Large Homes No matter the size of your home, the VTech DM1215-2 Two Parent Unit Enhanced Range Digital Audio Baby Monitor ensures you stay close to your baby with crystal-clear audio—even from the other side of the house or out in the yard. With an impressive range of up to 1,500 feet, you can move freely while still keeping an ear on your little one. This system includes two parent units, making it easy for multiple caregivers to stay connected. Both the parent and baby units feature built-in rechargeable batteries, so you can monitor wirelessly with added convenience. The baby unit also functions as a soft night light, creating a calming glow in the nursery to help your baby relax and fall asleep. Plus, built-in lullabies add another layer of soothing comfort right from the unit.
