re-analyse saved events for movement

[Mad Professor]

Good day all.

As per the title, is it possible to re-analyse saved events for movement?

I ask as I have my system setup just to record 24/7 @ 5FPS with no motion detection.

My system has space for aprox 7days then clears the old files, on an endless cycle.

I would like to know if I can some how re-analyse all my saved events over the last 7 days, and only show me ones that have detected motion.

Can this be done within zoneminder, or with some other software?

Thanks for your time.

Best Regards.

At this time I don't think Zoneminder can re-analyze images after they're recorded. However you can create a separate monitor that can record on motion if you want. It will take up a bit more room though whenever you have motion. Or if you want, you can have it record at a low frame rate and quality on alarms and then just search through your other footage.

Good luck.
