Re: Zoneminder not working, several errors

I looked at the log he posted a link to. Some cams are webcams or via capture card. Some are IP cams. He's having probs with an IP cam. Looking at the log he posted, that cam never worked.

Re: Zoneminder not working, several errors

The image is not displaying like the others above. How about you just describe the issue? "Got empty memory map file size 0, is the zmc process for this monitor running?" and "can't find process with command 'zma -m 2' " These are the errors I'm getting. The "zma -m 2" indicates monitor 2 having a ...

Re: zoneminder v1.32.3 on ubuntu 18.04 LEMP freeze randomly

... Haven't you a new idea why Linux is trying to enumerate all the features on the BRIX motherboard ? It's normal for Linux to enumerate the motherboard on boot. It does this to probe the motherboard and figure out what kernel modules to load and what kernel settings/modes to set that (hopefully) ...

Re: zoneminder v1.32.3 on ubuntu 18.04 LEMP freeze randomly

To look at your log file I had to download it. So, you have ZM running on Ubuntu on a Gigabyte BRIX GB-BXBT-1900 (basically, a SFF PC). Your log (it's BIG) seems to show ZM running OK - I saw no sign of any serious errors. No sign of a Linux crash or panic in the log. It appears the system just free...

Re: Zoneminder not working, several errors

You don't provide much information, but I'll give some feedback based on your pics. Since you are using /dev/video0 as the source it implies /dev/video0 actually exists, you are using an analog camera and analog capture card/device. If you get any of the card/device settings or monitor settings wron...

Re: Zoneminder keeps crashing

I've stopped logging to the web gui and the db; now it works without crashing, and when it does, it restarts without doing anything Your comment reminded me that I had to do the same sort of thing. My initial ZM 1.30.4 (on Ubuntu 18.04) setup ran fairly well at first with just one cam with logging ...

Re: What is the likely cause of pixellation?

Pixelation can happen if there are constraints on the stream. For example: relatively high frame rate for the resolution, color depth for a given bitrate. If the bitrate is set too low for the resolution+bit_depth+frame_rate, the encoder will still do its best to comply but pixelation/blocking can r...

Re: video export seems worse quality than watching footage?

My Ubuntu 18.04 ZM server (1.30.4) has a fairly low-end Nvidia GT-730 graphics card - but its gpu does support h264 encoding. The version of ffmpeg in the 18.04 repo supports h264_nvenc. So, I offload h264 video creation to the GT-730's gpu with this FFMPEG_OUTPUT_OPTIONS setting: -threads 4 -c:v h2...

Re: Configured for X Bandwidth

I have version 1.30.4 and the same problem. Is now a solution available? I run 1.30.4 (Linux). Console bandwidth default can be set per user account. Go into "Options", click on "Users". The "Bandwidth" default setting is the second to the last. Just click on the associated dropdown & select what y...

Re: cameras for object recognition

It is indeed hard to give a general answer, because "object recognition" implementations/goals vary widely. To recognize license plates reliably, you need excellent camera placement. Cams used for this typically have a good varifocal (variable focal length) lens, WDR and resolution that fits the app...

Re: Priorities ram? Cores? GPU?

Sure. But logfile and database IO is substantial on a ZM server monitoring lots of cams, which usually means - for an ssd based root fs - having /var mounted on a mechanical drive too. That is, if you want to greatly reduce numerous small writes to the ssd. That added complexity to run an ssd root f...

Re: Priorities ram? Cores? GPU?

Cams are Trendnet TV-IP320PI. These are apparently a re-branded Hikvision DS-2CD2012-I. Look the same & same specs. Supposedly I could install Hikvision's firmware but I'm just sticking with Trendnet's latest firmware (which is fairly recent). I found mine on Amazon. Trendnet also sells these as a t...

Re: Vstarcam and ZM 1.30.0 in Raspbian

The most likely cause is ZM cannot allocate enough shared memory. The shared mem usage you showed is probably not applicable because the capture daemon is probably not running because it crashed. This can give you some background info: https://wiki.zoneminder.com/Math_for_Memory_-_knowing_how_much_m...

Re: Priorities ram? Cores? GPU?

Wow thanks for the comprehensive reply! I've been doing some research on the ryzen. What kind of camera setup do you have attached to that system? Currently, 6 1.3MP Trendnet/Hikvision IP cams and an analog BTTV capture card for 3 720x480 B&W analog cams. I'll eventually add 3 more IP cams and mayb...
