One of my cameras is falling behind realtime...right now anything that happens shows up in ZoneMinder about a minute and a half past the event. This delay seems to increase with time (restarted zoneminder recently, it was at realtime, then shortly after restarting it was up to about 30 seconds behin...

I'm trying to figure out the black magic that is ZoneMinder motion detection. We have our cameras set up in an area where the lights are turned off and on regularly. I'm running into several problems: ZM doesn't always detect motion of people walking through zones, or don't detect until someone is h...
