Specify the video input channel.(1~4)
Specify the frame size. (qvga / vga)
Specify the JPEG frame rate. Selection range is as follows. For a frame rate lower than 1fps, use -. For
example, select -2 for 1/2fps.
VN-E4 and VN-E4U (NTSC)
30, 15, 10, 7.5, 6, 5, 3, 2, 1, 0, -2, -3, -5, -10, -15, -20, -30, -60

Only 1 frame of the JPEG data will be sent when this is specified as 0.
Specify the destination IP address.
