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 smoothlier video 
quality.
Regardless of the power line frequency setting (60Hz or 50Hz), the frame rates are selectable at 1fps, 
2fps, 3fps, 5fps, 8fps, 10fps, 12fps, and 15fps. You can also select 
Customize and manually enter a 
value. 
    Note that the fixed-focal lens module can attain a frame rate of up to 30fps.
