I've been looking around and find very little info on audio recording with ZoneMinder. Is it capable of recording audio to go along with my video? How do I get started on that? ZM does not supports any kind of audio. That's a bummer! Any news on this line from the wiki To Do List? Add sound support ...

Thanks for the reply. It seems that being patient helps a bit. I currently have 4 cameras recording (2048x1536) @ 4 fps with a load of roughly 1.7 (edit: it dropped to 1.14 now that I've been more patient). I've tried reading about load, but it still doesn't make much sense to me, because htop ...

Even lowering to 1 fps still sends the load well over 2.0 (dual core). That's still at the full 3MP resolution so I may try lowering that, but don't really want to. I also noticed that after stopping recording that nph-zms takes up 100% cpu for some time...is this because it's finishing up recording ...

Ok, so I finally found where the images are stored: /var/cache/zoneminder/events

Unfortunately there is also a /usr/share/zoneminder/events but nothing exists here...

PS. If you want to leave it in there but not taking any load while you experiment, try disabled. Obviously not convenient if you periodically want to look at the camera. Disabling appears to have no effect on the load, which is also strange. Stopping ZoneMinder does reduce load significantly. Well ...

Disabling appears to have no effect on the load, which is also strange. Stopping ZoneMinder does reduce load significantly.

One of my concerns is that adding a monitor increases the load significantly on the server (even when I'm not viewing that monitor). Is this normal? Why would the load increase in this situation? I guess it depends on what you are doing when you add it, e.g. if it is set to record or to do motion ...

Postscript: bear in mind that because (today) zoneminder saves jpg's and not actual video, if you plan to record all the time, or a lot of the time, this can make for huge storage requirements especially at high frame rates. I found I can store just shy of 2 weeks, 2pfs, seven 2048x1536 cameras on ...

So I have 4 x 1080p IP cameras connected to zoneminder as monitors with default 25fps. My server runs a Pentium G620 @ 2.60GHz (dual core) with 8GB of ram. With just the 4 cameras connected as monitors (not even viewing the monitors) my load seems to be somewhere around ~2 to 3. With all 4 cameras ...

Basically what bbunge just said. It is not realistic to expect six 1080p cameras to work on a 2.6GHz dual core machine without making compromises. It might work at 1-2 fps and no motion detection, but even that would be close. The only way to get a precise answer is to configure just one camera and ...

One more thing I just thought of...it appears zoneminder doesn't record or monitor any audio??? Are there any solutions for this?

So I'm planning my setup and expecting about 6 x 1080p IP cameras to cover my home. My headless Ubuntu server runs a Pentium G620 dual core at 2.6 Ghz with 8GB of RAM and plenty of storage, roughly 9TB. My first question is how many cameras can it safely handle with motion detection and recording? I ...

Possibly caused by this 9. Harden PHP for security. Edit the php.ini file : sudo vi /etc/php5/apache2/php.ini Add or edit the following lines an save : disable_functions = exec,system,shell_exec,passthru register_globals = Off expose_php = Off display_errors = Off track_errors = Off html_errors ...

14.04 Mmmm try this, I think I have it correct has been a while since I played with something not running at all. sudo zmpkg.pl start What about the in ZM GUI there is a Logs link anything in there? zmc -m1 if you have a camera called 1 should bring it up, or swap to your ID, or tell you what ...
