INTELLECTUAL ACCESS AND CONTROL SYSTEM Russian patent published in 2005 - IPC

FIELD: protection of property from trespassing.

SUBSTANCE: inside the protected building a video monitor is mounted with a button for controlling access, connected to microcontroller, connected to inside communication phone and display. Communication block with surveillance camera is set near entrance to building, with backlight block, access control block, made with possible opening of access door, indicator, dynamic and microphone. Also present is duplex communication channel, through which surveillance camera is connected to microcontroller, and microcontroller - to access control block and indicator, microphone - to inner communication phone, and phone - to dynamic. Video monitor has serially connected video memory block, connected to microcontroller, video digitizer, images analysis block, connected to microcontroller output, and processing block, connected to microcontroller input. Communication block has presence detector, made with possible detection of human presence in door vicinity and forming a control signal, and symbolic-digital keyboard, output of which through duplex communication channel is connected to microcontroller. The latter through duplex communication channel is connected to presence detector, output of which is connected to inputs of backlight block and surveillance camera.

EFFECT: higher efficiency.
