Finger print recognition doorbell - does it exist?

["John Andrews" <groups@xxxxxxxxxxxxxxxx>]

Hi

Is there a device out there that can serve as a finger print recognition
door bell?

i.e. I'm after the end solution being homeseer saying, as an example:
"Dad
is at the door" when he rings the doorbell.

Also the ability to log strangers fingerprints, and to notify me that there
is an unknown person at the door.
The logging of fingerprints for future use is the key here (think along the
lines of abusive carol singers when I told them politley I had no money on
me).

Cheers in advance for any help.
