ZoneMinder Forums

Hello all, I recently purchased several Logitech 4000 USB webcams that I want to attach to clients through the premises to monitory entry and exit ways. These clients are all running ubuntu server 10.04. I have a central server, also running ubuntu 10.04, that I would like to run zoneminder and connect via network to the other machines with usb cameras plugged into them.

I was searching for a simple way to expose the webcam via network and found webcam-server, I have it working on all clients now and I can view all the webcams via my browser by switching the address and port.

I have not been able to figure out how to add the webcam-server feed to zoneminder though. Is this something that is possible?

The webcam-server feed is just an address to a .jpg file.

Is there a better option for exposing the webcams? I would like to use something with as little depenencies as possible as some of the clients are VERY slim and I don't want the security or administration overhead of having sql/web servers in multiple locations.

Thank you all very much for your time, I look forward to using zoneminder and anticipate that it is a great suite of software.

Yeah you should be able to just add the path to zm if it really just is a jpeg there are no problems.

I have the server running, the address to the image is:

http://minerva:4254/minerva.jpg

Here is how I am adding the monitor:



No luck so far when I click on the name... nothing shows.

I can browse to the location and see the monitor... but nothing in zm.

help!

I still can't figure it out. Is there another utility I can use in linux to expose the webcam feed?

try using the ip rather than name.

also in the zm server run this
wget http://minerva:4254/minerva.jpg

make sure it saves a image.

when I perform that wget I get a jpeg back, exactly what I expect to see in zm. How should I set the monitor up to use this?

With all kinds of variations of the monitor add source menu I cannot get it to capture the stream from webcam-server.... this cant be this difficult. Can someone please! help me out.

That looks ok.

Double check the image properties, if the size is out it'll fail.

Easiest way is to right-click the image in firefox and check the properties.

If that doesn't work, check the logs. I'm betting you'll find there's a message about shmall or shmax.

640x480 colour is too large for ubuntu to handle by default.

echo 134217728 >/proc/sys/kernel/shmall
echo 134217728 >/proc/sys/kernel/shmmax

Try again. If that works;

To change them permanently you will need to edit /etc/sysctl.conf and add the following lines (for example) :-

kernel.shmall = 134217728
kernel.shmmax = 134217728


(from the wiki faq)

are thise webcams UVC ? if so why not run mjpeg-streamer
i tried it with a 9000 pro with 10.04 and it works great @ 640x480 and 15fps.
the picture is awsome.
bty the way this will run on a router and is in the openwrt package list so it can't be too heavy.
