This Network Camera offers real-time H.265, H.264 and MJPEG compression standards (Triple
Codec) for real-time viewing. If the
H.265
or
H.264
mode is selected, the video is streamed via
RTSP protocol. There are several parameters through which you can adjust the video performance:
■ Frame size
You can set up different video resolutions for different viewing devices. For example, set a
smaller frame size and lower bit rate for remote viewing on mobile phones and a larger video
size and a higher bit rate for live viewing on web browsers, or recording the stream to an NVR.
Note that a larger frame size takes up more bandwidth.
■ Maximum frame rate
This limits the maximum refresh frame rate per second. Set the frame rate higher for smoother
video quality and for recognizing moving objects in the field of view.
If the power line frequency is set to 50Hz , the frame rates are selectable at 1fps, 2fps, ~ to
50fps. If the power line frequency is set to 60Hz, the frame rates are selectable at 1fps, 2fps, ~
to 60fps. You can You can also select
Customize
and manually enter a value.
The frame rate will decrease if you select a higher resolution.
■ Intra frame period
Determine how often for firmware to plant an I frame. The shorter the duration, the more likely
you will get better video quality, but at the cost of higher network bandwidth consumption. Select
the intra frame period from the following durations: 1/4 second, 1/2 second, 1 second, 2 seconds,
3 seconds, and 4 seconds.
