Loud sounds should trigger the alert - woud be a useful safety feature

It could save a life. My neighbor was shot and murdered, right next door at a house which is very close, within feet of the camera and of course since there is no sound trigger the camera did not record anything. I gave police recordings of cars coming and going but the actual sound would have been useful and unfortunately there is nothing there.Please add this feature! What if someone breaks glass or there are shots fired - the camera should record above a certain decibel level and I'm sure this is possible.
