From time to time it'd be nice to have a remote control camera
connected to my Pi. Most likely use would be watching for
unwelcome critters in the garage or garden.

Knowing absolutely nothing I downloaded zoneminder. It looks
like a much more complex system than I need, but it's available.
At this stage I'd just like to find out if it runs on a Pi4
running up-to-date 64 bit RasPiOS. It's installed but the man
page is little help and running zmu reports a permissions error.

Any tips or links would be much appreciated.

Runs fine on a RPi4

You don't run it manually, it start (should) automagically at boot time,
go to <http://ip.address.of.RPi/zm/index.php>

There you can set up cameras etc. etc. etc.

It helps enormously, now I know which way is up 8-)

Still, there seem to be problems:

If I try to visit
http://localhost/zm/index.php
I get a 404.

If I try to run the daemon manually I see:

bob@raspberrypi:~ $ sudo zmc -d localhost
03/27/24 13:43:48.107397 zmc_dlocalhost[400666].ERR-zm_db.cpp/55 [Can't connect to server: Access denied for user 'zmuser'@'localhost']

03/27/24 13:43:48.107614 zmc_dlocalhost[400666].FAT-zm_config.cpp/67 [Can't connect to db. Can't continue.]

Zoneminder was set up using sudo apt install zoneminder, no manual configuration.

The errors above make it look like maybe some sort of install script needs to run
for setting permissions. Sudo zmu reports the same permissions error as zmc.

I did check that
sudo more /etc/zm/zm.conf
displays a reasonable looking file.

Any further hints appreciated!

Thanks for writing!

Bob,

Have you read <https://wiki.zoneminder.com/Dummies_Guide>?

<https://zoneminder.readthedocs.io/en/stable/userguide/

<https://wiki.zoneminder.com/How_To>

There is a lot of good stuff there - though some is a bit arcane :-)

That's new to me. I tried using

but still see

At least the config file is now readable.

Indeed, I'll have study it a while. I wish there had been a hint in the
man page to the links you supplied.

Thank you very much!

Bob,

Don't run zmu from the command line it's not how it works :-)

Zoneminder is a service that runs all the time in the background doing its stuff, there is a mysql database at the heart of this system with .php web pages.

ps aux |grep zm provides

<code>

</code>

localhost/zm (or ip.of.your.RPi/zm) should give you a web page with a top
bar with 'useful stuff' in it e.g.

<https:/www.dctower.co.uk/files/zm-top-bar.png>

Here 'add' allows new cameras to be added etc.

As I say zm should be started on boot - but it might depend on how you've installed it - it was a long time ago now & I can't remember I just update
it when I think about it - this thread has just prompted my to do an apt update, upgrade.

Regards

That was what had me stumped, I expected it could be stopped and started manually or in the startup scripts. My bad....

ps aux |grep zm provides

That command offered proof that zoneminder's not running.

I'll try rebooting at some point to see if that makes any
difference. I'm not likely to want it running all the time,
can it be stopped and started _without_ rebooting?

Thanks for all your help!

I've not actually tried it as I run mine 24/7/52 but ...

sudo systemctl start|stop zoneminder.service may/should/might work

or

sudo service zoneminder stop|start (I think all RPis system use systemd
these days so systemctl is more likely)

HTH

Thanks for all your help!

No problems - I remember struggling at first, but as I say I can't
remember what I did to solve it. A clean install via apt-get I think ...
then it all just worked (c).

I've not used zoneminder, but have used 'motion' for watching wildlife (https://motion-project.github.io/) which works fine on an RPi (both
with USB cameras and the RPi camera).

How does one guesstimate which cameras will work? Zonemaster has a list,
but I didn't see one for motion. It looks like the better-performing
cameras start in the mid-hundreds of dollars so a correct choice matters.

I'm not aware of a list of tested cameras, though a quick glance at the documentation suggests that one which supports Video4Linux2 should work.

But I wasn't trying to persuade you to switch away from zoneminder, just suggesting something else you might try if zoneminder doesn't work out.

I'll admit that zoneminder appears to be a fairly ambitious project....
was hoping motion might be closer to cheap plug-and-pray setup.

The initial mystery (figuring out what's chewing up a lemon tree) has
been resolved the old fashioned way. Still, knowing what's possible
and affordable will be useful the next time something like this comes
up.

Thanks to everybody who responded, I'm slightly less ignorant now!
