Learn CompanionAnswer Common Questions
Answer the real question.
Do I need a PTZ camera controller?
Use one when a single operator needs faster presets, smoother moves, and direct camera selection.
Should I use HDMI, SDI, NDI, or USB?
Choose by distance, reliability, network skill, and whether the setup must repeat every week.
Why is my PTZ controller not connecting?
Most failures come from IP address, protocol, port, camera mode, or network segmentation issues.
When does hardware control beat software control?
Hardware matters when operators need tactile confidence, fewer clicks, and repeatable show timing.
Do I need vMix replay control?
Replay control makes sense when sports or events require fast mark-in, mark-out, angle, and return-to-live actions.
What setup should a small team start with?
Start with the simplest workflow the team can operate reliably, then add control where mistakes still happen.
