The invention discloses a housing-unit
access control device based on
wireless communication and housing-estate
access control system. The housing-unit
access control device based on
wireless communication comprises a building-door terminal and a plurality of indoor terminals, wherein the building-door terminal comprises a building-door controller, a
wireless communication module, a display screen, an electric lock controller, a camera, an electroacoustic device and a digital key; each indoor terminal comprises an indoor controller, a wireless communication module, a display screen, an electroacoustic device and a control key; and the wireless communication module of the building-door terminal is in wireless communication connection with the wireless communication modules of the indoor terminals. The invention has the advantages that the cost is reduced by utilizing free communication of a 3G-
visual communication trunking network, and the defects of more wires in the rooms and difficulty in maintenance in the access control device and
system are effectively overcome; the indoor terminals are connected with a security
detector, so that when an owner is not at home, a personal mobile terminal can be used for monitoring indoor security equipment remotely and carrying out remote meeting; and when no person is at home, guests can enter the room in advance for waiting.
