4. Getting Alarm from VN-V685/686/686B
4.1. Procedure
1) The client establishes a TCP connection to port number 32040.
2) When motion is detected from the video image of VN-V685/686/686B, or when there are changes to the alarm input
(make or break), VN-V685/686/686B will send out alarm information in the following format. The first 2 lines indicate
the current alarm input status (make or break). The following 1 line indicates whether motion has been detected.
peripheral.input_pin.pin(1).status=break<CRLF>
peripheral.input_pin.pin(2).status=break<CRLF>
video.input(1).detection(motion).status=on<CRLF>
3) The client can disconnect TCP32040 to end the alarm acquisition.
