My friend of 20 years came to see me. I was not at home. He left a note on the door. By the time I found the note he was gone. I have had many women tell me they are afraid to be home alone and when someone comes to their front door, they panic. The DoorMan automaticly answers the door, take messages, allows the home owner to see who at the door and communicate to them without opening the door. I have been working on this project for 20 years and finally received a patent and ready to introduce it to the public.
