R20B supports H264 codec that provides a better video quality at much lower
bit rate with different video quality and payload.
To do the configuration, you can do as follows:
1. Click Account - Advanced to find Video Codec.
2. Check the H264 Code name square box.
3. Set up parameters according to your need.
4. Click Submit tab to validate the setting.
Parameters Set-up:
Codec Name: Check to select the H264 video codec format for the door
phone video stream. H264 is the video code by default.
Code Resolution: select the code resolution of video quality among four
options: QCIF, CIF, VGA, 4CIF and 720P according to your actual network
environment. The default code resolution is 4CIF.
Codec Bitrate: Select the video stream bit rate (Ranging from 320-2048).
The greater the bitrate, the data transmitted in every second is greater in
amount therefore the video will be clearer.. While the default code bitrate is
2048.
