Audio Codec Configuration
The device supports four types of codecs (PCMU, PCMA, G729, and G722) for encoding and decoding the audio data during the call session. Each codec varies in terms of sound quality. Higher bandwidth means the device can capture more detail, leading to clearer sound and higher sample rates capture more data, reducing distortion and preserving sound quality.
You can select the specific codec with different bandwidths and sample rates flexibly according to the actual network environment.
To set it up, go to the web Account > Advanced interface.
Please refer to the bandwidth consumption and sample rate for the codec types below:
Codec Type | Bandwidth Consumption | Sample Rate |
|---|---|---|
PCMA | 64 kbit/s | 8kHZ |
PCMU | 64 kbit/s | 8kHZ |
G729 | 8 kbit/s | 8kHZ |
G722 | 64 kbit/s | 16kHZ |
Video Codec Configuration
The door phone supports the H264 codec that provides better video quality at a much lower bit rate with different video quality and payload.
To set it up, navigate to the web Account > Advanced interface.
Resolution: Specify the code resolution for the video quality. The default is 720P(1280X720 pixels).
Bitrate: Select the video stream bitrate. It varies by the resolution. The default is 2048.
Payload: The payload ranges from 90-119 for the audio/video configuration file.
