Paranoid parents (usually first time parents are like that) will find that the Philips Avent DECT ought to do its bit in soothing their fears, thanks to the guarantee of zero interference from various wireless devices as well as the added peace of mind that its encrypted connection offers. In addition, the Avent DECT comes with a humidity sensor that alerts you to dry conditions which could irritate your little one’s throat alongside a temperature sensor that helps monitor baby’s room for optimal comfort. The base unit will include a night light as well as a range of specially selected lullabies that helps your child fall asleep when restless. Its rechargeable batteries are good for 24 hours and the Avent DECT has a working range of approximately 900 feet. Guess $150 to $200 is not too large a price to pay for some peace of mind.
