IP Cameras Stops Recording Event with a Signal Event

Post by gtorres_12 »

Hello :) I'm new to ZoneMinder Forums and ZoneMinder itself. I have setup three IP cameras that 'should' record 1-day long events (86400 is set in Section Length in Misc Settings of an IP cam). However, after for about 200 or more seconds those events are eventually stopped and a new Signal Event that has around 10-20 frames. I'm not too sure, but does this have anything to do with X10, and can this be fixed with some changes in X10 tab? If it could be fixed there, what settings should I do? I have read ZoneMinder Wiki about this and couldn't figure out what setting I should make.. Any help is greatly appreciated. :)

I don't think this is a ZM problem but a max file size based on your file system block size. As an example: if the block size is 1 kB then max file size is going to be approx. 16 GB (ext3). I have no idea what your running but I'd check this out before any changes to your ZM setup.

Thanks for the reply, and sorry for my late reply. I use ext4 for my file size. I checked my file system block size using the command

Code: Select all

dumpe2fs /dev/sda5 | grep -i "block size"
and it returns 4096 (4 kB) for my block size. This means my max file size is around 16tB, right? But my IP cameras still create those Signal Events. I have tried some local USB webcams before and they could record for 1 whole day without any cuts. How can I do the same for my IP cameras?

Also, on my IP cameras, how many frames captured before it is stopped with a Signal Event changes; there are times it can only capture 200 to some thousands of frames (as can be seen on the first screenshot), and some events go up to hundreds of thousands of frames (as can be seen on the second screenshot). The signal events that cuts the recording events are either 11 frames or 21 frames, and when I view that, it shows the frame where it stopped and the screen turns to blue.

I guess I have the same problem. What could cause these signals i wonder? I have one camera in local network and two in remote location (2x Axis and 1 DLink) - all of them have these Signals at random times. So this should not be a network or specific camera issue..
It does not matter, if I set the recording to Record or Modetect. If there is no motion, these Signals still gets generated..
I have no such problems with my analog cameras (also running in zoneminder with capture cards)

This is todays events from my remote camera. What's weird - it ran without problems for 10 hours and then the Signals started. Other ones sometimes manage to run 3 to 4 hours without Signals.
I don't get it :?

Well- I just noticed this forum is for 1.24 and i have 1.25.
But it looks like others have problems with this issue as well: http://www.zoneminder.com/forums/viewto ... 29&t=19175
