Nothing more to add, the camera recognizes many breathing movements even under a thick mattress and even when we add a cushion to elevate the mattress! It took us no false alarms (neither true by the way), my baby is now 8 months. Really easy to use and even the installation is not complicated. Only automation to take: turn off the alarm before leaving baby bed! I recommend all parents like us who are a little afraid. I do not regret at all the investment given the tranquility that this device brings.
