This has probably been asked before but my wife and I just purchased our new home and currently have a standard doorbell wired with the chime on the insider. My wife does not want a new doorbell because she likes the sound of our current one. My question is: If I purchases the hard wired smart doorbell, will it still utilize the current bell we have in the house??

Also: What is the difference between the standard wired door bell and that one that comes with the smart security?
