HiSense BabySense V Infant Movement Monitor ($129)
At least 5 times a night I'll wake up and go check on my son in his crib, just to make sure he's still breathing. The HiSense BabySense V could do this work for me. As long as you place the device's two sensors underneath the baby's mattress, the system will alert you if the baby stops moving for more than a few seconds, allowing you to intervene if there's something wrong.
