    4 Technical Descriptions 4.1 Block Diagram The block diagram of Video intercom system is shown in Fig 4.1. Image signal root: The image data is converted into NTSC signal by Camera unit, and the NTSC signal is modulated into FM signal. FM signal is sent to the Monitor station through the interphone cable with ASK signal which modulated from command signal and voice signal.
  • Page 10 Call Signal from Door station: When the call button is pressed in Stand-by mode, the short between lines causes the DC voltage of the interphone cable to go down. The monitor station detects this voltage reduction and then rings. Then LCD of the Monitor station is turned ON. Fig.
