If it "hears" noise, it calls, which is great, but if the call fails (this happened to me), it wont reset and youll have no way of knowing if it worked. Less importantly, but very annoying, if it calls and baby just cried for a sec and doesnt need attention, you have to go reset the baby monitor app again. If they could fix this, this would be great.
