Oak D Lite fixed vs auto focus for surveillance camera?

Which is better for surveillance camera, fixed or autofocus? Why?

rlaferla Probably auto-focus - as your camera won't have any vibrations. That's the only downside of auto-focus; when the camera is under vibration, it will cause the lens to vibrate freely which will create blurry (color) frames.

erik Thank you.

Oh and as another datapoint @rlaferla - as long as your camera will be at least 1.5 feet from what it's looking at, fixed-focus will be fine.

Almost all security cameras are fixed focus for this reason. As then there's no risk of auto-focus hunting because of bugs close to the camera/etc.

Brandon Thank you. Fixed focus it is.
