and 30 fps. The unit “fps” stands for “frames per second.”
Note: The frame rate is up to 15 fps at 1280x1024, and up to 30 fps at 640x480. However,
if you would like choose frame rate over 15 fps, the IMAGE SIZE of H.264/MPEG-4/MJPEG
setting page has to been selected 320x240 or 640x480 at the same time.
Quality:
z
Auto: The quality and bitratee will be adjusted automatically according to the frame
rate.
z
Fixed Quality: Select the value of quality among Medium, Good, Delicate and
Excellent.
Fixed Bitrate:
Set the bitrate of MPEG-4 image transmission for a line. You can select one value among
64Kbps, 128Kbps, 256Kbps, 384Kbps, 512Kbps, 768Kbps, 1Mbps, 1.5 Mbps, 2 Mbps, 3
Mbps, 4 Mbps, 5 Mbps, and 6 Mbps.
Note: Concerning how to select the suitable image quality for Fixed Quality or Fixed Bitrate,
please refer to the CHAPTER 10. APPENDIX / A. Frame-rate & Bitrate Table.
IP interval:
It’s the ratio of i-frame & p-frame. You can select one among 1, 5, 10, 15, 30, 60, and 120.
The ratio smaller, the streaming smoother.
Note: The IP interval value means a ratio of “ P-frame / I-frame “ in a certain section of
frame sequences. The ratio lower, the live view clear. However, live view will lag if the
bandwidth isn’t big enough. In this situation, you have to choose another bigger IP interval
value to solve the problem.
Note: If Video clip format of General Menu, which is for recording compression, is chosen
MPEG-4, the IP interval option will appear “Auto” automatically and can’t select. The limit is
for avoiding damaging the recording quality of 5 seconds temporary-saved video recorded
on FTP server.
