ABSTRACT:
An electronic mailbox including a mailbox housing (12), a door (16), an alarm system (20), a door sensor (34) a first timer, a second timer, a programmable controller (26), and a power source (42). Housing (12) defines an opening of a size and shape to receive mail. Door (16) is of a size and shape to cover opening (14). Door (16) is movably operable between an open state and a closed state. The alarm system (20) is controlled by the controller (26) between a first unarmed state and a second armed state. A keypad (22), door sensor (34) and timers input signals to controller (26). The timers along with the door state determine whether the armed state or unarmed state is in effect. Controller (26) sends output signals to activate the alarm system when the door (16) is opened by an unauthorized user. An authorized user inputs a deactivating code into the keypad (32) to deactivate the alarm system. Optional LED mail deposit indicator, latching (locking) mechanism, and illuminating lights(s) may be provided.
