BabySense 5s infant movement baby monitor

Infants move constantly while sleeping and even in the brightest light these movements can be difficult to see. The BabySense Monitor rests under the mattress and alerts you when your baby's movement stops or slows. With two sensors located underneath the crib mattress, the Babysense Movement Monitor maintains detection of movements and micro-movements. If there are no movements for a period of 20 seconds OR if less than 10 movements per minute, the Babysense Movement Monitor will emit a loud alarm that can be easily heard from a distance. This alarm does not shut off if baby stirs. It requires an adult caregiver to reset it. Babysense Movement Monitor uses 4 AA batteries and does not emit a wireless signal. This means it is less likely to receive interferences from cell phones and other wireless devices. The passive sensors are totally safe and emit no radiation of any kind which could harm the baby
