Vertically rotate the video.
A large “Key frame interval” value can reduce the bit rate, but if
there is a packet loss during transmission, it will cause image
corruption. “Fix bit rate” and “Key frame interval” are only available in
“MPEG4” mode. The video quality may be poor due to the sending
of maximal frame rate within the limited bandwidth, which is when
images are moving rapidly. Consequently, to ensure detailed
video quality (quantization rate) regardless of the network, it will
utilize more bandwidth to send the maximal frames when images
change drastically.
To fix the bandwidth utilization regardless of the video quality,
choose Fix bit rate and select the desired bandwidth. The video
quality may be reduced in order to send maximum frames with
limited bandwidth, especially when images change drastically.
For higher video detail regardless of the bandwidth selection,
select Fix quality and select a video quality level. This setting will
utilize more bandwidth to send the maximum frames when images
change drastically.
Horizontally rotate the video. Check options both if the Network
Camera is installed upside down.
