Click the stream item to display the detailed information. The maximum frame size will follow your
settings in the above Viewing Window sections.
This Network Camera provides real-time H.264 and MJPEG compression standards (Dual Codec)
for real-time viewing. If the
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. A higher quality stream can also be
recorded 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, 3fps, 5fps,
8fps, 10fps, 15fps, 20fps, and 25fps. If the power line frequency is set to 60Hz, the frame rates
are selectable at 1fps, 2fps, 3fps, 5fps, 8fps, 10fps, 15fps, 20fps, 25fps, and 30fps. You can also
select
Customize
and manually enter a value.
The single stream mode allows a 60fps frame rate.
