ZoneMinder Forums

Just rebuilt my system using freshly formatted drives, Ubuntu 20.04 server and Zoneminder 26.5. Things run fine except for alert playback where the alert frames are grayed out. Non-alert frames playback normally. I am stumped. Please help.

It looks like I found the fix. Under Source>Method change UDP to TCP. ONVIF had designatedd UDP during initial setup so I left it at that. Turns out TCP is a better choice.
