I posted here a week or two ago (thread: http://www.zoneminder.com/forums/viewtopic.php?t=9757) about our purchase of two Arecont Vision 3130 cameras (specs: http://www.arecontvision.com/products_3130.html) for monitoring my condominium building's parking lot in high resolution. We already have one Axis 207w watching over the lobby.

The Arecont Vision is a great camera. It was easy to set up and get an image in my browser, but I can't get it to work with ZM. I hope somebody can help.

The cameras do output either a static JPEG or MGPEG stream. The Arecont Vision manual gives plenty of url options to configure the video stream to how you want it. Using this URL string, I can get a great picture in my browser:
http://192.168.1.202/mjpeg?res=full&x0= ... r=HTTP/1.1

This produces a 1920x1200 mjpeg image at 1 frame per second.

In the ZM source setup, I have the following configuration
host: 192.168.1.202
port: 80
path: /mjpeg?res=full&x0=0&y0=0&x1=100%&y1=100%&quality=12&doublescan=0&fps=1&ver=HTTP/1.1

It's just not working! I've raised the shared memory in the kernal to about as much RAM as the machine has. Here are outputs from zmdc.log (monitor 2 & 3 are the Arecont cams):

Does anybody have any clue what is going wrong? I;m also attaching the Arecont instruction manual to this post, in case it is helpful.

There are three possibilities,
Shared memory needs to be large enough, although you never want to use much more than half (as a safe rule) to leave memory for other important processes.
The configuration of ZM and the cam must match for image size and palette, if the cam is sending a 1920x1200 image and ZM is expecting as configured 640x480, then it will not work, check your settings.
Third is there is no standard for mjpeg so if the headers are put together in a fashion that zm can't recognize, then it will not work. There are several cameras that do not work with ZM eventhough they produce mjpeg because they have weird headers which is why we have a compatibility list.

heythisisnate

Have you resolved the problem?

Posted: **Mon Dec 03, 2007 11:15 pm**

No, the problem is not resolved yet. I tried cordel's suggestions, and just can't figure out what exactly is wrong. I tried looking at the headers, but I don't really know what I'm looking for.

The good news is that we finally got our internet connection hooked up, so I can make the camera feeds public and you experts can try and help me out.

The two Arecont cameras are available at http://alhambrahoa.no-ip.org:8445/ and http://alhambrahoa.no-ip.org:8446/. This will bring you to the camera's web interface.

You can get a raw mjpeg stream with this path:
http://alhambrahoa.no-ip.org:8446/mjpeg ... r=HTTP/1.1

Can anybody help me figure out why ZM won't read it?

Thanks,
Nate

first of all, resolution is not 1920x1200, it rather is 1280x1024, second, camera is very very picky about how request that is sent to it is formated. in particular it does not like this line in src/zm_remote_camera.cpp:

Code: Select all

		snprintf( request, sizeof(request), "GET %s HTTP/%s\n", path, config.http_version );

find the line, change \n to \r\n, recompile zmc, reinstall zmc , set ZM to use regexps, ver 1.1 http and you are good to go.

well, resolution apparently changes with light as camera uses either smaller b/w sensor or bigger color sensor, at night res=full gives 1280x1024, but in daylight it is 1920x1200, so you will have to do something about this.

Yes, this is correct. The camera has two lenses and switches from the color to the b/w sensor after dark. The max resolutions are different. What do you mean "do something" about this? What problems would this cause? Any suggestions about what I should do?

Posted: **Tue Dec 04, 2007 2:51 pm**

when you define monitor, you hardcode resolution and zoneminder does not try to adjust monitor resolution to the actual images coming from camera. so you will either have to instruct camera to return fixed resolution images at all times (1280x1024 for example) or set up zoneminder in some weird way so that it pulls higher res. image at day and lower res. image at night.

I spoke with the customer support and engineers at arecont.
they said you could crop the image in day mode to 1024x768, but that will affect Field of View ( FOV ). A possible lens change could mitigate the impact of that.
One of my clients will have a couple of these cams next week, and they also dropped a chunk of change on some bosch software for recording.
They also have 4 of the 5 MP cams from the same vendor.
I will take a zoneminder machine there for some testing, but they will be using the bosch on windows setup.
<just threw up in my mouth a little>

The engineers told me they have a couple of day/night cameras being released in January, with one lens and a mechanical cut filter. They will be offered in 3 and 1.3 mp.

Arecont is not ready for zoneminder. I traded a few more emails with the engineers there, and they don't have enough flash memory to properly trigger ZM for a motion event. They claim they will have that feature in march, but I am not impressed wtih the images I am getting from the 3 MP cameras I set up.
