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, MPEG-4, and MJPEG compression standards (Triplel

Codec) for real-time viewing. If the H.264 or MPEG-4 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. Note that a larger frame size takes

up more network 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 and the resolution is set to 3-Megapixel, 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.
