The Philips Avent SCD506/05 Audio Baby Monitor is the perfect nursery accessory to give you the confidence you need. Providing you with the reassurance of feeling close to your baby, even when you are not in the room, this monitor gives you the most reliable connection with improved crystal-clear sound, a soothing night light and calming lullabies – perfect for your little one. With an integrated two-way communication talk-back function, you can communicate and soothe your baby whilst in a separate room; giving you the ease and simplicity you need. Sound-level lights indicate if your baby makes a noise. The five LED lights are activated to indicate the level of sound within your baby’s room, even when the parent unit is muted. Not only this, but the parent unit will also alert you when your monitor is out-of-range or when the power is low, helping you to make sure that you are always connected to your little one. The indoor range is up to 50-metres and an outdoor range of 330-metres, giving you the tools you need to watch over your baby with confidence. The unique smart eco-mode automatically minimises your transmission power and hence increases your battery lifetime. The closer you are to your baby, the less power is needed for a perfect connection. DECT technology guarantees zero interference from any other transmitting products, such as other baby monitors, cordless phones and mobile phones. While the advanced data encryption provides a secure and private connection; so you can be sure that with the Philips Avent SCD506/05 Audio Baby Monitor, you are the only one listening to your little one.
