A multimedia entry home (or factory) security system transfers live audio and video (A/V) to a remote location, can be connected wired or wirelessly, and would run on very low power if wireless. Internet connection allows the owner/caretaker to answer via smartphone if the “doorbell” is pressed, leaving the external visitor no wiser as to a physically absent owner.
