"Blue Screen" issue

[francis3]

Hi all,
quite new setup here,
as described in my previous forum post:

viewtopic.php?f=36&t=27960

It runs quite well now and I'm really happy with it.

But every now and then (maybe every 3/4 days), now 7 days from the last event
one of the two monitors shows the "blue screen".

I've checked the stream from the camera with an external program (vlc), an the video is fine.
In the meantime the system is not loaded at all.

To get the image again I have to disable the monitor then re-enable it, or restart ZM.

Here the logs of today's event:

Best way to deal with the issue?
Maybe a script that periodically check the logs and restart zoneminder?
Or a curl call to disable and then re-enable the camera?
From what I understand reading the logs the monitor is working fine.
Except from:

Code: Select all

 WAR [Signal: Lost]

Btw, after the warning, monitor2 seems Capturing and Analyzing just fine:

Any help would be appreciated.

This has been addressed before. It boils down to this:

Some types of cameras will occasionally drop out. Other brands are not affected.
Developers are aware of the issue.

You have a couple of options, including: upgrading to newer ZM, making a script via API that restarts lost cameras, using modect, using a different brand of camera, adjusting ZMWATCH.pl timeout level in options... If you are interested in more discussion, search the forums.

What I do is:
Change zmwatch.pl timeout to a higher number (MAX_RESTART_DELAY is the name of the config)
Change affected cameras to modect, which appears to work better for me.


Just curious, what brand / model of camera do you have?

[francis3]

Hi snake!!!
Thank you for your kind answer!

The cameras are a couple of Foscam Cube Model C1 v3
with the last available firmware.

It's a budget choice, but the image quality is not bad for my purposes.
Btw, I have to say the plugin issue to gain control of the cameras via HTTP interface is an absolute nightmare.

They are starting point for my ZM project, gonna get more serious cameras asap.

To solve the issue, I'm gonna start with the easy option.
Modifying the suggested parameter MAX_RESTART_DELAY, going to double the default value of 600.

The two cameras are already working in modect mode.

Then I'm gonna investigate the API. But how do I spot a lost camera? From the logs posted above, to me, after the event,
end the warning

Code: Select all

WAR [Signal: Lost]

the camera is working fine


Again thx,

If you are using rtsp try forcing tcp.

[francis3]

Yes, I'm using rtsp.
And the remote method is already TCP.


Thx bbunge,
