NTP time skew can be on the order of 100ms. If the audio/video is desynced by 30ms, it can definitely be noticeable. Some people are more sensitive than others, and it also depends on the particulars of the content.
Edit: Another commenter points out that in some situations, it's even necessary to align the time that the frames start, which necessarily requires sub-frame precision.
- Ajedi32 2y agoIt's almost never going to be that bad unless you're going out over a terrible internet connection. Worst case you could have a way to configure one camera to run its own NTP server and have the others sync to it over LAN. That would get you sub-frame (<1ms) precision easily.
