USB camera stop working after a while hardware\software problem?

[david1234]

Hello ,
I'm using zonminder with only 1 usb camera connect to my pi
after 2 days it stop working
this is hte pi syslog

after reboot the pi - it start to work again for 1 day ~
is it a camera problem and need to replace it?

Thanks,

First problem :- You are using a Raspberry Pi with an inadequate power supply, which will cause you all sorts of odd behaviour, crashes, data corruption, problems with plugging in USB devices ...

Code: Select all

 Under-voltage detected! 

That aside, when you plug in the USB camera and it works, you have a "/dev/video0" device, yes? Good.

When the USB camera has stopped, do you still have a "/dev/video0" device, or has it moved to "/dev/video1" -- a sign that it disconnected and reconnected leaving the old one hanging around. This can happen with USB memsticks too (they can creep along a letter when they glitch, and become e.g. /dev/sdc when you expected /dev/sdb ...)

ls /dev/video*

next time it fails and see if it moved ...

[david1234]

after pi reboot , it's works 4-5 hours
then stop working

I run the command and this is what I get:

Code: Select all

pi@raspberrypi:~ $ ls /dev/video*
/dev/video0  /dev/video1  /dev/video10  /dev/video11  /dev/video12

but while running lsub I get this:

Code: Select all

when I run
fswebcam image.jpg
I get an image using video0(I can see the mage in my files and the image is good)

Code: Select all

 fswebcam test.jpg
--- Opening /dev/video0...
Trying source module v4l2...
/dev/video0 opened.
No input was specified, using the first.
Adjusting resolution from 384x288 to 352x288.
--- Capturing frame...
Captured frame in 0.00 seconds.
--- Processing captured image...

so what does it mean?
it's seems that the camera is working ,

and what can I do ?

Thanks ,

"/dev/video0 /dev/video1 /dev/video10 /dev/video11 /dev/video12"

So did you run that command when ZoneMinder was NOT WORKING? (Apparently refusing to capture from /dev/video0 as per your original screenshot?)

That's a lot of video input devices. But 10,11,12 are because of https://www.raspberrypi.org/forums/view ... 3#p1527503, so you can ignore them. So you have two possible video devices there.

Do you have the raspberry PI camera attached to the board, and is that /dev/video0 or /dev/video1?

I still wonder if the camera is "going away", which is why the capturing at 27fps turns to ... "I've heard nothing for 7 seconds" -- because /dev/video0 (the device you've selected) has disconnected and reconnected as /dev/video1 or even higher numbers, as it happens more than once, leaving behind broken non-working stale "/dev/videos" ...

ZM will cope with cameras disconnecting (and will reconnect to them), but if they come back up as a different /dev/videoX number (or reboot and pick a new IP address for network cameras) then it doesn't stand much chance of recovery.

the zonmidner is running
and also the USB camera function is "Enable , Monitor - but it's in red (like it's not connected).

I have only the USB camera connected , no other video device is connected to the Pi.

I havve try to cahnge the source to video1\10\12 - nothing

but (as you can see in the previos post) when I run the fswebcam it's working and capture the image using video0.

after reboot the pi it's working on video0 for ~ 4 hours.

this was a fresh installation on zonminder (I have nothing else running on the PI )

what else it could be ?

Thanks ,

I tried the pi reboot and it works as normal for 4-5 hours then stop working.

I used ZoneMinder, and there was also so many issues, don’t know why. So I was fed up and gave up on ZoneMinder. I hired a software developer to build my app for my survelliance camera/ It worked via Bluetooth and I totally loved it. If you want to find out more about app developing and how you can integrate apps in your daily life for fun or for security measurers you can read this article
