Re: Zoneminder keeps crashing

It can help to reduce resolution, you are correct.

Very important: You need to reduce the resolution at the camera sending end, as well as the Zoneminder receiving end. And they must exactly match.

It sound like you have only changed it at Zoneminder, which is now trying to tell you to sort it out.

Re: this just happened overnight

Although you've changed nothing, you've not said what resolution the camera is supposed to be returning, vs the resolution you've set in Zoneminder It looks like the camera is delivering fewer pixels per line than you are telling ZM to interpret. Measuring off your PNG in GIMP, I make it about 320 p...

Re: date format problem

Do not mix computer stored data and data presented to humans by computers. I'm not mixing them up. As a human, I find it utterly baffling when programs present data in formats that make it hard to understand. So the formats I mentioned such a "05 02 19", which is the 5th of February this year, 2nd ...

Re: date format problem

Disclosure: I'm non-American too. Personally, if any date formats are going to be hard coded in and enforced, I would much rather see YYYYMMDD enforced absolutely everywhere, because it is unambiguous, and naturally sorts correctly. Using DDMMYYYY vs MMDDYYYY in a "who's right, America or UK?" battl...

Re: day/night IP bandwidth load

Could the increase in data (data rate) be because the camera is trying to encode an image that is more noisy than in daytime? The penalty of trying to work in reduced light level?

If the camera is encoding at constant-quality, the data rate will go up to represent the noise.

Re: day/night IP bandwidth load

Steve's response was in relation to an interloping posting by Spam Smith (now deleted), and my subsequent mention that the "Report Spam" button was broken. It is *that* which is fixed (by tinkering with servers). Thanks Steve.

Re: Filter by date/time shows one wrong result per day

If you mean the first event in the list, around midnight, then it is exactly what you asked for. It's just not what you meant to ask for ;) Start: 01/28 23:50 (Monday) End: 01/29 00:00:00 (Tuesday) Think about each filter line ... Starts on Monday or later. Yes. Ends on Friday or less. Yes.

Re: RSS Feed for Forum

While you're tinkering, can you look to see why the "Report Post" button gives an instant 404 Error? (It happened before, and was fixed, but it's back :( )

Re: Image degradation

See other posts regarding "FFMPEG Smearing" tips and also try switching from UDP to TCP, as UDP (by design) will drop packets now and then. TCP is designed to not allow that sort of thing. It looks like you have data corruption part way down the frame leading to the rest being blurry. Also, try turn...

Re: Cannot write to content dirs('events','images')

Yes, I say I - I mean root, Ah well, a lot of things work when you are root, which fail when you are an ordinary user. This is why the permissions need to be correct. Running and testing as root is not a good solution. Apologies for the ls -la example error, didn't notice your extra "www" there! ro...

Re: Cannot write to content dirs('events','images')

When you say "I can create...", who is "I" ... root, an ordinary user, or otherwise? It sounds like you might have a permissions problem. Maybe the hint is the 2nd half of the error message :- "and are owned by the web account user" What does "ls -la /usr/share/zoneminder/" "ls -la /usr/share/zonemi...

Re: day/night IP bandwidth load

Hmmm. Joined 4 minutes before first posting, to resurrect an old thread, with an irrelevant reply. If there was a referral link to buy the D3100 at amazon (for a kickback to the link poster), then I'd say it's spam. Otherwise, it's just very badly targetted advertising.

Re: video export seems worse quality than watching footage?

Glad you sorted it, you can turn the quality and file size down using -q:v 2 .... 9 (larger = worse quality) until you thing it looks bad. Should have said: My cameras are 640x480, so at higher resolutions -q:v 1 may be a lot bigger than I thought :) No idea about Windows compatibility, I use VLC/Xi...

Re: video export seems worse quality than watching footage?

@alabamatoy -- those *are* the settings from ZoneMinder :) (Look under the FFMPEG_OPTIONS settings):

What I meant was that FFMPEG (inside OR outside of ZM) needs guiding as to what you expect it to do. If you don't, the defaults can be less than useful.

Re: video export seems worse quality than watching footage?

Are there options? Yes there are, sometimes when throwing video at FFMPEG (outside of ZoneMinder) it seems to pick the most horrid quality possible to remind you to read the manual and do something about it. I use :- -r 25 -q:v 1 -f avi -vtag XVID -g 30 -bf 2 -vf "hqdn3d,lutyuv=y=gammaval(1.4),unsha...
