This Network Camera provides 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 dierent video resolutions for dierent viewing devices. For example, you can
congure 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 eld of view.
If the power line frequency is set to 50Hz , the frame rates are selectable at 1fps, 2fps, 3fps,
5fps, 8fps, 10fps, 12fps, 15fps, and up to 25fps. If the power line frequency is set to 60Hz, the
frame rates are selectable at 1fps, 2fps, 3fps, 5fps, 8fps, 10fps, 12fps, 15fps, and up to 30fps.
You can also select Customize and manually enter a value.
