■Mode
The Network Camera offers two choices of video compression standards for real- time viewing:
If
■Frame size
Select the video size. A larger frame size takes up more bandwidth. The frame sizes are selectable in the following resolutions: 176 x 144, 352 x 240 and 640 x 480.
■Maximum frame rate
This limits the maximal refresh frame rate per second. Set the frame rate higher for a smoother video update.
If the power line frequency is set to 50Hz, the frame rates are selectable at the following rates: 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 the following rates: 1fps, 2fps, 3fps, 5fps, 8fps, 10fps, 15fps, 20fps, 25fps and 30fps.
■Intra frame period
Determine how often to plant an I frame. The shorter the duration, the more likely you will get a better video update, but at the cost of higher network bandwidth consumption. Select the intra frame period from the following duration: 1/4 second, 1/2 second, 1 second, 2 seconds, 3 seconds and 4 seconds.
■Video quality
A complex scene generally produces larger file size, meaning that higher bandwidth will be needed for data transmission. Therefore, if Constant bit rate is selected, the bandwidth utilization is fixed at a selected level, resulting in mutable video quality performances. The bit rates are selectable at the following rates: 20Kbps, 30Kbps, 40Kbps, 50Kbps, 64Kbps, 128Kbps, 256Kbps, 512Kbps, 768Kbps, 1Mbps, 2Mbps, 3Mbps and 4Mbps.
On the other hand, if Fixed quality is selected, all frames are transmitted with the same quality; bandwidth utilization is therefore unpredictable. The video qualities are selectable at the following settings:
Medium, Standard, Good, Detailed and Excellent.
