ZoneMinder Forums

Good morning (o;

Just installed zoneminder 1.34.22 on my Shuttle P51U which serves as a test system for NVR softwares..
So far tested bluecherry and shinobi...but wasn't happy with them...

Now I've setup 4 RTSP streams (low quality 720p cameras) and the systems runs fine....even watching all 4 streams in a browser doesn't bring the system down...

I see for each stream a zmc capture and a zma analyzer process....

Now my question..are those processes threaded?

The final setup would be at least 1440p cameras and 4 to 6 streams....so is there just one zmc/zma thread running per stream or can they run on multiple cores/threads on the CPU if needed?

Is there a general rule like "resolution x streams = 2 * core/thread count" ?

For a test I tried just one 1440p stream...although the CPU load of zmc and zma were both below 50% the recording showed only artifacts...and as such marked everything as alarm frame....

Currently I had following Intel NUCs in mind:

- NUC i5-10210U, 4 cores, 8 threads
- NUC i7-10710U, 6 cores, 12 threads

Not sure if I should go with a Ryzen system and 8 cores, 16 threads and a NVidia GPU....though haven't seen any positive impact in using Intel GPU at the moment...


thanks in advance

Hmm...really nobody has a comment on this?

Or should I go big with a 12-core AMD Ryzen and a NVidia GPU for 6 * 5MP h264 streams?
