Vtech Safe & Sound Audio Monitor gives you peace of mind, anywhere, anytime, roam anywhere in the home, hear all the special sounds your baby is making. DECT 6.0 digital technology provides crystal clear transmission, eliminating the annoying white noise you hear from analog monitors. The only sounds you hear are coming from your baby. With up to 1,000 feet of extended range, you can carry the parent unit with you everywhere you go, even out into your yard. For times you need added peace, turn the sound down on the parent unit and rely on the visual sound alert LED's to indicate sound levels in the baby's room or get alerted of sound from the vibrating alert. You can also speak to your baby from another room or even outside with our Talk-Back feature that turns the parent unit into a walkie-talkie device.
