[. . . ] /api/param?application. ftp. password=%00 admin, operator (There is no API for acquiring passwords. ) Refer to Section 5. 4 for details on transmission of JPEG input channel, frame size, prerec and postrec via FTP. Allowed users Note Acquiring Chattering Guard Time Setting of Alarm Input from VN-700 Format Example /api/param?peripheral. input_pin. pin(Number). chatter When acquiring chattering guard time of alarm input 1 /api/param?peripheral. input_pin. pin(1). chatter peripheral. input_pin. pin(1). chatter=100&200 OK Acquire the time setting to prevent chattering in the alarm input. admin, operator, user Example of response Interpretation Allowed users 35 5. Alarm Environment Setting Setting Chattering Guard Time of Alarm Input for VN-700 Format Example /api/param?peripheral. input_pin. pin(Number). chatter=data When setting the chattering guard time for alarm input 1 /api/param?peripheral. input_pin. pin(1). chatter=150 peripheral. input_pin. pin(1). chatter&200 OK Change the time setting to prevent chattering in the alarm input. admin, operator Example of response Interpretation Allowed users Acquiring Alarm Output Time Setting from VN-700 Format Example of Response Interpretation /api/param?peripheral. output_pin. pin. duration peripheral. output_pin. pin. duration=1000&200 OK Acquire the current alarm output duration in millisecond. If alarm output is set in alarm action, this parameter can be acqurired by following API. /api/param?application. event(Number). action admin, operator, user Allowed users Setting Alarm Output Time for VN-700 Format Example Example of response Interpretation /api/param?peripheral. input_pin. pin. duration=data /api/param?peripheral. input_pin. pin. duration=50 peripheral. input_pin. pin. duration&200 OK Change the alarm output duration in millisecond. /api/param?application. event(Number). action admin, operator Allowed users Acquiring Alarm Output Status from VN-700 Format Example of Response Interpretation Allowed users /api/param?peripheral. output_pin. pin. status peripheral. output_pin. pin. status=make&200 OK Acquire the current alarm output status. admin, operator, user Changing Alarm Output of VN-700 Format Example Example of Response Interpretation /api/param?peripheral. output_pin. pin. status=data /api/param?peripheral. output_pin. pin. status=break peripheral. output_pin. pin. status&200 OK Change the alarm output. When the alarm output time is zero, alarm output is changed as this API specifies. When the alarm output time is not zero, alarm output is changed as this API specifies, then alarm output is changed again after the alarm output time. These are equivalent to the features on the Motion Detection page of the WEB setting page. 10000000 00000000 00000000 , , , Storage in bytes will begin from the LSB and represented in a hexadecimal value as shown below. 01 00 00 , , , The hexadecimal value denotes the 18 ASCII characters acquired via this API that are expressed in ASCII codes. For example, the following character string will be returned when only the top left and bottom right blocks are masked. video. input(1). detection. area=010000000000000000000000000000000080 admin, operator, user Example of response Interpretation Allowed users 38 5. Motion Detect Setting Motion Detect Mask for VN-700 Format Example /api/param?video. input(Number). detection. area=data When setting the motion detect mask of video input channel 1 /api/ param?video. input(1). detection. area=000102030405060708091011121314151617 (1). detection. area&200 OK Change the motion detect mask. VN-700 enables motion detect to be adjusted for each of the 4 video inputs. Refer to the item on "Acquiring Motion Mask from VN-700" on the interpretation of this character string. admin, operator Example of response Interpretation Allowed users 39 5. These are equivalent to the features on the Serial Port page of the WEB setting page. However, specification of control device and camera address are not supported by API. Refer to the instruction manual for details on the Serial Port page. Acquiring Serial Port Baud Rate Setting from VN-700 Format Example /api/param?peripheral. serial(Number). baud When acquiring baud rate of Serial Port 1 /api/param?peripheral. serial(1). baud peripheral. serial(1). baud=9600&200 OK Acquire the serial port's baud rate. [. . . ] Use sendbuffer (API argument for sending data to VN-700) to increase the outgoing buffer size of VN-700. In addition, increase the window scale and incoming buffer size at the client's end as well. If the OS used by the client is Windows, window scale can be altered by changing the registry. Refer to the Windows manual for details on operation of Windows registry. [. . . ]
