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 offers 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 for you to 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. 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, 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, and 15fps, 20fps, 25fps, and 30fps. You can 
also select Customize and manually enter a value.
