Compatible Audio Codes

The following codecs are found to work well with VI’s IP Server and are most commonly used by known camera manufacturers:

• L8 @ 8K (Uncompressed 8-bit audio)
• L16 @ 16K (Uncompressed 16-bit audio)
• G711 ULAW and ALAW @ 8K and 16K (NOTE: ULAW is preferred but if you’re outside of USA/South America, and/or Japan consider using ALAW if ULAW does not work)
• G726 40/32/24/16
• AAC Low Complexity (NOTE: Bitrate is 128kbps or less)
• AMR Audio
   

Transmission Priority for i-PRO Cameras

If Audio is enabled, the transmission priority mode will be updated to the Frame Rate priority mode in all i-PRO H.265 camera series. This will assist synchronizing Video and Audio.

Recording Type

For audio/video synchronization, it is highly recommended that Record Always recording type is used with all audio functions.
