Hi. I noticed some of my cameras constantly changing their color from green to orange and back to green. After checking the logs, I noticed the following recurring errors: 'zma -m 5' exited abnormally, exit status 11 The 5 number is diffrent in every error of course. Any idea what could be causing t...

Thanks for the info.

And what about the accuracy? Is it accurate in the same way as the blobs method?

Hi.

After playing with the zones a bit, I wonder if someone ever used other alarm check method then "blobs", and have found it more accurate or faster?

Hi.

I started logging event stats to try and tune the zone. Are there any instructions how to use these stats?

Best, High sensitivity - no events at all.

The default setting works fine.

I tried to set the zone to best, high sensitivity - and it stopped recording anything altogether. Only when I restored the default zone settings, it started recording again.

I thought it should actually improve the sensitivity, not to worsen it?

If I have a moderately fast camera (~10 fps), should the % blend be lower or higher?

Hi Cordel. I actually checking the forums often, but usually just lurking in shadows :). The blend reference is the default 7%, perhaps it should be increased? I thought that fast movements might cause these issues. Could it be, that if person moves too fast, its entry to the watched area won't be c...

Hi. Thanks for the answer. AFAIK I know ZM, it stores the frames in circular buffers, and allows the CPU to analyze them for motion. If the CPU has not enough time to process them all, the older frames overwritten by new ones, and you get the "buffer overrun" error. This is not the case he...

Thanks for the reply, your guess as good as mine :). The hardware is dual CPU, dual-core Opteron 2 Ghz, 2 GB RAM. I increased the post and pre buffers to 50 frames each, but still it doesn't help. The load is about 5-7 in peaks, which AFAIK fine for such configuration. Moreover, if the CPU had not e...

Hi. I recently noticed that ZM misses significant motion in frames. The most visible symptom is people appearing and dis-appearing in recordings, without any recordings of how they entered or left the watched area. The people figures are large enough, and should have triggered the detection the mome...

Hi.

Seen it in action in small computer store near me, owners said that his friend has made some screensaver "wrapper" that basically launches the video client.

Don't think either it could be sold separately, rather then included with some package (like ZM)?

Hi.

Nice idea. So it basically will auto adjust the blending reference according to frame rate, and prevent loosing parts of the event in the beginning, or splitting to two events due to fast frame rate at the end of the event?

Hi.

1) 6-8 fps
2) full view coverage
3) 10 cameras, 2GB RAM, 2.4Ghz Pentium Core Duo

Thanks.

Hi.

I added more cameras to ZM, and have a considerable performance drop. I still would like to keep the zones covering the entire viewpoint. What settings are recommended for zones to reduce load?

Thanks.
