■ Frame size
Select the video size. Note that a larger frame size takes up more bandwidth. The frame sizes are selectable in the following resolutions: 176 x 144, 320 x 240 and 640 x 480.
■ Maximum frame rate
This limits the maximum refresh frame rate per second. Set a higher frame rate for smoother video quality.
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.
■ Intra frame period
Determine how often to plant an I frame. The shorter the duration, the more likely you will get better video quality, but at the cost of higher network bandwidth consumption. Select the intra frame period from the following durations: 1/4 second, 1/2 second, 1 second, 2 seconds, 3 seconds, and 4 seconds.
