Video Quality Settings For Stream 1/2—Set two streams for the PVC300 PTZ
Internet Camera for different viewing devices. For example, set the PVC300 PTZ
Internet Camera to a smaller frame size and a lower bit rate for viewing on mobile
phones. Or, set the PVC300 PTZ Internet Camera to a larger video size and a
higher bit rate for viewing on web browsers.

Mode
The PVC300 PTZ Internet Camera offers two choices of video compression
standards for real-time viewing: MPEG-4 and JPEG. If MPEG-4 is selected, it
is streamed in RTP encapsulation over UDP. There are four dependent
parameters provided in MPEG-4 mode for video performance adjustment.

Resolution
The video resolutions are selectable at the following settings: 640x480,
320x240, and 176x144. Note that a larger frame resolution takes up more
bandwidth.

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.

If Fixed quality is selected, all frames are transmitted with the same quality
and bandwidth utilization is unpredictable. The video quality is selectable:
Medium, Standard, Good, Detailed and Excellent.
