4.3.2.2.
Main Board
Call Button (SW301)
Outline of Operation : When a visitor presses the Call Button, a chime tone will ring at the monitor station.
FM Signal Modulator (IC200)
Operating Power Supply : +5V (+5V : 2, 9pin)
Package : 24pin SOP
Outline of Operation : The frequency modulation of the video signal taken in from Camera Unit is carried out.
+5V Regulator (IC202)
Input Voltage : +20V
Output Voltage : +5V
Package : SOT-23-6W
Outline of Operation : It generate from +20V to +5V.
Voice Amplifier (IC100)
Operating Power Supply : +5V
Package : 8pin SSOP8
Outline of Operation : The voice signal from the Microphone is amplified and sent to the Monitor Station.
The voice signal from the Monitor Station is amplified and sent to the SP amp (IC102).
Speaker Amplifier (IC102)
Operating Power Supply : +5V
Package : VSP-8pin
Outline of Operation : The voice signal from the Voice amp (IC100) is amplified and sent to the Speaker.
MCU (IC203)
Operating Power Supply : +5V
Package : 32pin QFP
Outline of Operation : It communicates with the Monitor Station by AM signal through IC200.
It controls of the camera, the electric lock, and the lighting, by the operation from the Monitor Station.
Control (zoom processing, backlighting compensation) of a camera is carried out by I2C communication.
At night, MCU turns on LED200 and LED201 automatically based on the information from IC204.
Illumination sensor (IC204)
Operating Power Supply: +5V
Package: 4pin COB
Outline of Operation: The surrounding brightness is detected and the level is outputted to MCU.
