Axis Cameras

[ikarus]

Hi all, just want to give my help to this community.

The AXIS 2100 Low Frame Rate Problem
I've experienced the low frame rate problem with the Axis 2100 and tryed to fix it wasting hours. I''ve noticed that the image quality on the Camera Own Settings was Very Low (it means 250KB per frame) so just try to put it to Low (25KB per frame).
So I went from the 2-3fps to a more likely 12.5fps at 640x480 using this path /axis-cgi/mjpg/video.cgi?resolution=640x480.

My problem
I'm going to set up a system like this:
3 Axis 205,
1 Axis 206M,
1 Axis 2100,
1 Axis 211,
1 Axis 2110

Sometimes the power line goes off but the server is on a UPS. What happens when the power comes back is that ZM is not able to get images anymore (This with an Axis 2100) unless you restart it. HELP

You have the server on a UPS are the cameras?
Is it that ZM is not logining back into the camera cause they have a password?
Is there anything in the logs that might be usefull?
Thanks,
Cordel

Sorry for the false alarm, It happened only twice when the system wasn't stable because of the shared memory SHMGET. Now I've got 300Meg Shared so the program works stable and it reconnects with no problems.

Thanks you all

One thing to be aware of is that if the capture daemons restart frequently (as they will if the remote camera is inaccessible) then the controller daemon will gradually expand the intervals between retries up to a maximum of 15 minutes (I think), to prevent excessive load caused by continuously restarting processes. Thus if you have power go off for a length of time, when it comes back on to the cameras it may be up to 15 minutes before the next scheduled restart attempt.

I think I should make this configurable though.

Ok, after alot of trial and error and tons of help from Phil and everyone and everything posted in the forum i finally have my setup working, i will try to fine tune it before we set this up out in the field.

To make it easier on myself i made a directory in /var/log called zoneminder and have all the logging being written there.

This is being built for my old Landlady, someone keeps breaking into her house, she has setup a alarm system and x10 camera but basically they keep getting disconnected and she has no evidence of anything happening, stuff just stops working every few days.

I am streaming this offsite, smile shitheads, your on candid camera! Can't wait to bust some loser. This will be setup behind a Linux Desktop, yes i am migrating her off of windows and setup zandros and a little iptables magic to get it off her network and over to mine.

There were so many little things i found all over the forum that helped me out, increasing memory, setting up the shared memory segment. paths and other setting but nothing where i found it all on one page so after much babbling here it goes.

Camera Axis 206w
Mandrake linux 9.2 <--this will have to get updated very soon, sucks to have to do it all over again.

## finding shared memory segment ##
[root@superbox zoneminder]# ipcs

------ Shared Memory Segments --------
key shmid owner perms bytes nattch status
0x0052e2c1 0 postgres 600 1466368 3
0x7a6d2001 65537 apache 700 36864508 0

to test if that is correct you can run /etc/init.d/zm stop
then run it again and you will see it missing now
------ Shared Memory Segments --------
key shmid owner perms bytes nattch status
0x0052e2c1 0 postgres 600 1466368 3

## changing shared memory ID ##
In the one log i had this

==> /var/log/zoneminder/zmwatch.log <==
Can't get shared memory id '2053971969': No such file or directory
Can't get shared memory id '2053971969': No such file or directory

from inside of Options you can change the segment ID
on the System screen

I had this in my logs from several process's

## Camera Settings ##
Cameras IP=192.168.0.208
Path=/axis-cgi/mjpg/video.cgi?
this pulls faster framerates of around 10fms
or
Path=/axis-cgi/jpg/image.cgi?
pulls off the camera at around 4fps

I hope this helps out someone, most likely it will be me in a few weeks when this box gets upgraded, i break everything and cant remember what worked and how i did it.

And Phil, Thanks for building what I see as a better mousetrap!!! Hopefully we catch our Rat.
