ZoneMinder Forums

Hello.
Testing performance of a computer I want to use to run zoneminder I tried adding a single camera as multiple monitors (I'm expecting to have more cameras, but I could only get one). Performance-wise, everything is OK - CPU load and CPU utilization are low, but I noticed that each monitor recorded a different number of events even though they all have the same settings and they share the same camera.

It happens when I have as little as two monitors reading the same camera, both set to max 5 fps, which IMO rules out the camera, for it should be able to handle 25fps.

Has anyone noticed anything similar? Am I wrong in expecting the numbers to be the same?

Thanks for all responses, if you need more info I'll happily provide it.

Well for starters monitors could each be grabing a diffrent 5fps pic so 5 fps might be 5 10 15 .. etc to the camera.

If useing network.

However if its analog it should be the same because of the way it captures..

Thanks for your reply.

Yes, the camera is connected via network, not locally.

If I understood you correctly, increasing fps of the monitors should decrease the difference in number or recorded events. I'm going to try that now, because I don't want to lose events.

OK, I've increased the max FPS limit to 15 on both monitors but there still is a difference in the number of events recorded by them.

Example from the last hour:
Monitor 1

Monitor 2

Summary: Monitor 1 (M1) recorded 3 events, Monitor 2 (M2) recorded 2 events, but only one event was recorded by both monitors. So M1 recorded 2 events that were not caught by M2 and M2 recorded one event that was not recorded by M1. Duration of these events is close to 2 seconds, which IMO means that each monitor grabbing a different pic is not the cause...

The box running zoneminder atom 330 (2 physical cores, 4 virtual) powered. Average CPU load is ~2.5, CPU utilization ~50%

Help please, I really want to know the cause of this.

Hate it leave it like this but i relly dont know unless your zones are set differently.
