If your daughter can climb out of the crib, then she is too big for the crib.
Also, if I accept your premise that a baby sleeping is inherently dangerous, then this is just an added layer of safety. It doesn’t remove safety.
But really safety is a highly lame way of framing this. what you want is more hours asleep so you have this thing try to hypnotize the baby with lights, sound, vibration, and it only alerts the parent(s) if it fails
Eventually it could just straight up talk to your three year-old read it a second bedtime story, dispense a cup of water convince it not to hang out with the bad kids at school etc
