problem with same camera

[andreas7]

Hi, I have a problem with zoneminder 1.28.1, I have 15 monitor, 10 axis connected with rtsp
/mpeg4/media.amp on 554 port

and 5 camera microtik onvif 2 mpx with rtsp /h.264 on port 8557
With the axis I haven't problem, but avec other, after 3/4 days turned on the cam freeze and I ping it but if I try to connect with the web interface is blocked. The problem is always resolved when i restart the camera... but after 3/4 days the problem reoccurred...
Can you help me to resolve the problem?
thank you

If you can't access the cameras directly (their OWN web pages) then it sounds like they've crashed. This could be bad firmware, causing a memory leak, brought on by you using them continuously.

1) Update firmware in cameras to latest, if the manufacturer has fixed the problem ...

2) If there's an automated way to reboot the cameras via HTTP access (maybe a form with a button on you could simulate) write a script to pro-actively reboot it to stop it happening?

3) Otherwise it means cutting power to the camera now and then to force a reboot.

I found similar bad behaviour with my IPCams (DLink DCS 900s) -- after a few weeks of constant running they keep disconnecting the IP link.

A weekly scheduled reboot sorted that out.

(For my camera, that was as simple as ...)

Code: Select all

wget --http-user=root --http-password=MYPASSWORD -O /dev/null --post-data="Reset= Yes " http://cam01/DoReset.HTM

Maybe you will find something similar?

Hi,

We have the same issue on a Zoneminder 1.28.1 with Ubuntu Server 14.04.1 (without GUI)
It is a 7x24hr surveillance operation. Thinks are working good, but after a couple of days we notice in the montage view that 4 to 8 cameras appears to be frozen.

At this point if we point directly to the cameras IP through any browser, they are working normally. So the problem seems to be zoneminder

Configuration

Cameras
- We have 80 HD IP cameras (1280x720) on the server.
- 100% Cameras are PoE 802.3at full comply
- Cameras are configured as RTSP with libavcode option (we also try ffmpeg and it seems to work fine too, so we decided to stay on libavcode).
- Cameras are streaming at aprox. 15fps
- Cameras LAN port is 10/100 Mb fast ethernet.

Server
- The server is 2 x Opteron 4000 octa core processors (total 16-core server) + 16 GB DDR3 ultra fast 1600Mhz memory.
- Server has 2 Gigabit port
- We have 8TB RAID5 hard disk.
(Yeap I know is a big one, we decided a big server because the huge load of HD streaming)

Operator
Operator is looking at the cameras through a dedicated 6 core (2.8Ghz) computer with 8 gb of memory

Network
- The entire LAN networlk we set up is with Gigabit network, 1 core switch (54Gbps troughput) + 6 edge switches (44 Gbps througput each one)

Any advice about this issue?

Thank you we appretiate.

I have this issue as well and when I refresh the browser window it forces a logging back in of the user. Gets very annoying.

I have had the same issue with the libvlc. Go back to ffmpeg or the remote source type. May work much better for you.

That sounds like a beast of a system! Good job and thanks for trying ZM!!!

Thank you & thank you bb,

Today our expert engineer is going to change to ffmpeg and try your suggestion.
I will write later for the results.

Well we started to play withZM 3 years ago, but to be honest we never thought we would have the opportunity to work on this kind of projects, nor going against video surveillance server leaders as Samsung and Axis.

We build our own server (industrial finished).
Jejeje and it is not one, we have 2 servers and more than 130 HD cameras now working.
One server with 80 cameras.
Servers have never go over 45°C (monitor room without air conditioning) and load seems to be stable below 12 (of total 16 cores).
From the operator point of view, we decided to arrange cameras on 3 industrial TV screen 42inch (1920x1080).

Please take a look we have just uploaded a couple of pictures...

Thank you again and regards,

Hi bencollinz,

Which browser are you using?

We have good results with firefox, but remember to apply the zoneminder plugin for best performance.

If you have few cameras then chrome is also ok.
But for huge quantity of cameras, then we had bad results with chrome.

Explorer, please forget about it.

Regards,

Giuseppe

I've only ever used FF. Thank you, though.

Men I forgot to write back, you are a genius.
Going back to ffmpeg run everything smooth.

Moreover, when we disconnect temporally some camera for maintenance activities, zoneminder shows them again without doing anything when we reconnect cameras back.

Thank you very much,

Giuseppe
