The BW 3001 features a Digitally Encrypted System for Secure Digital Crystal Clear monitoring. It protects against eavesdropping and hacking for added Peace Of Mind. With a handy “Walkie Talkie” Function, you can now talk to and soothe your baby remotely. The BW 3001 also comes with a selection of Lullabies to play to your baby. This system comes with a 2.3′′ Colour LCD Display Receiver so that you can see and hear your child, even during the evening with Night Vision. It also contains a multipurpose adjustable clamp that simply enables the camera to secure to a shelf or stand freely on a drawer unit, out of reach of baby/children. The system can even be expanded to accommodate 4 cameras.
