The Babymoov Simply Care Monitor is an affordable baby monitor which has two channels. The monitor uses Analogue Technology which lowers the Electromagnetic waves your baby is exposed to at such a young age compared to other Audio Baby Monitors on the market. This monitor has a range of 300m & has 2 channels. It also has the VOX function which means the monitor is on a 'silent mode' but will alert you when your child makes a noise. This is a great function for battery saving in monitors. The monitor also comes with 2 alarms; one acoustic alarm & one visual alarm allowing you to never miss when they most need you. Volume control is also an included function & there is also a battery level indicator so you should always have plenty of time to replace the batteries before it is too late!
