Audio & Video Codec Configuration

Audio Codec Configuration

The door phone supports three types of Codec (PCMU, PCMA, and G722) for encoding and decoding the audio data during the call session. Each type of Codec varies in terms of sound quality. You can select the specific codec with different bandwidths and sample rates flexibly according to the actual network environment.

To do the configuration on device web Account > Advanced interface.

Please refer to the bandwidth consumption and sample rate for the four codecs types below:

Video Codec Configuration

To set up video codec on web Account > Advanced interface.

Parameter Set-up:

• Name: check to select the H264 video codec format for the door phone video stream. H264 is the video codec by default.
• Resolution: select the code resolution for the video quality among four options: CIF, VGA, 4CIF, and 720P according to your actual network environment. The default code resolution is 4CIF.
• Bitrate: select the video stream bit rate (ranging from 128-2048). The greater the bit rate is, the larger the data transmitted every second in amount. Therefore the video will be clearer. While the default code bit rate is 2048.
• Payload: select the payload type (ranging from 90-119) to configure the audio/video configuration file. The default payload is 104.

Video Codec Configuration for IP Direct Calls

To do so, you can go to Phone > Call Feature > IP Video Parameters.

Parameter Set-up：

• Video Resolution: select the code resolution for the video quality among four options: CIF, VGA, 4CIF, and 720P. The default code resolution is 4CIF.
• Video Bitrate: select video bit rate among six options: 64 kbps, 128kbps, 256kbps, 512 kbps, 1024 kbps, and 2048 kbps according to your network environment. The default video bit rate is 2048 kpbs.
• Video Payload: select the payload type (ranging from 90-119) to configure the audio/ video configuration file. The default payload is 104.

Configure DTMF Data Transmission

Go to Account > Advanced > DTMF interface.

Parameter Set-up:

• Type: select DTMF mode among six options: Inband, RFC2833, Info+Inband, Info, Info+Inband+RFC2833, and Info+RFC2833 based on the specific DTMF transmission type of the third party device to be matched with as the party for receiving signal data.
• How to Notify DTMF: select among four types: Disable, DTMF, DTMF-Relay, and Telephone-Event according to the specific type adopted by the third party device. You are required to set it up only when the third party device is to be matched with adopts such modes: Info, Info+Inband, Info+RFC2833, and Info +Inband + RFC2833.
• DTMF Payload: set the payload according to the specific data transmission payload agreed on between the sender and receiver during the data transmission.
