Max. FPS: Enter the FPS (frames per second) per viewer that you require. For NTSC, the maximum FPS
is 30.
JPEG Quality: Quality value (0 ~ 100) can be specied for the MJPEG codec. 100 indicates best quality.
GOP Settings: GOP (Group of Pictures) ‘P’ Frame count is used with the H.264 and MPEG-4 codecs.
The number of frames in a GOP is 1 (for the GOP itself) plus the number of P frames. For example, if you
set the P frame count to 59, the GOP size is 60 frames.
Bit Rate Control
Variable bitrate
• Unlimited: When unlimited is selected, there is no limitation on bitrate. This option is used for
devices with sufcient storage when high quality images are required.
• Limited: Setting a bitrate limit prevents the stream from exceeding that limit.
• Q value: You can set the Q (quantization) value for image quality when the bitrate is not constant.
Constant bitrate
You can set the target bitrate from 128 to 4096 Kbps. This parameter is useful when the device has
limited storage.
