I installed a rpm base zoneminder 1.22 in a FC6 system. When I try to connect to a network camera (Arecont Vision) the camera always return a http 1.0 version not supported. I checked the setting of http version in the option section of ZM, http 1.1 was checked.
Does anyone know what's the problem?

Here is the tcpdump data

Did you restart ZM after checking http 1.1?

Posted: **Mon Sep 24, 2007 5:16 pm**

Yes, I restarted ZM.

Posted: **Mon Sep 24, 2007 9:17 pm**

Which exact version of ZM are you running?

Also can you check that the value of the http version is in your database, use the following query from within the mysql client.

Code: Select all

 select * from Config where Name like "%http_version%";

Thanks for the reply,

Now ZM is issuing a http 1.1 request but the camera is still reply with version not supported.

There is a possibility that your camera is objecting to a missing line feed on the http version line, depending on the version. Look in zm_remote_camera.cpp for the line

Code: Select all

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

and check is has \r\n and not just \r or \n.

I installed the rpm version so I canot check the source code. Can I hardcode it into the source option in the configuration of a new monitor? ie something like remote host path - "/livevdeo.html%5Cr%5Cn"

Posted: **Thu Oct 04, 2007 9:16 pm**

I compile in from source and now the problem solved. However, I still cannot get any picture from the camera.

To get video from the camera I need to point the browser to http://192.168.1.11/livevideo.html and the browser display the live video.
The livevideo.html is a gzip file
unzippingit get the following
<html>
<head>
<META HTTP-EQUIV="Expires"CONTENT="0">
<META HTTP-EQUIV="Pragma"CONTENT="no-cache">
<META HTTP-EQUIV="Cache-Control"CONTENT="no-cache">

<SCRIPT>
var theDate=new Date();
var reload_timer;
var rtt; var rto=30;
var alpha=0.8;
var beta=2;
var ubound=20;
var lbound=0.2;
var srtt;
var previostime=theDate.getTime();
var firsttime=1; var access=1;
var ssn=theDate.getTime();
function startstop() { access=!access; }
function loading() {
var currtime;
theDate=new Date();
currtime=theDate.getTime();
rtt=(currtime-previostime)/1000;
if(firsttime) {srtt=rtt; firsttime=0;}
previostime=currtime; srtt=((alpha*srtt)+((1-alpha)*rtt));
rto=beta*srtt;
if(rto>ubound)rto=ubound;
if(rto<lbound)rto=lbound;
document.hiddenimage.src="/img.jpg?ssn="+ssn+"&id="+theDate.getTime();
}
function preload() { if(access)loading(); else clearInterval(reload_timer); }
function showimage() {
clearInterval(reload_timer);
document.visibleimage.src=document.hiddenimage.src;
document.visibleimage.width=document.body.clientWidth;
document.visibleimage.height=document.body.clientHeight;
reload_timer=setInterval("preload()",(rto*1000));
}
</SCRIPT>
</head>

<body leftmargin="0" topmargin="0" marginwidth="0" marginheight="0">
<div id="id_static"style="position:absolute;display:none;left:0px;top:200px;width:100px;height:100px;z-index:1">
<img src="/img.jpg" name='hiddenimage'onLoad='showimage()'>
</div>
<img src="/img.jpg" name='visibleimage'onLoad='setTimeout(preload,0)'>
</body>

</html>

Is there anyway to make it work?

thanks,

Alex

you need to know the jpeg url

maybe

<ip>/img.jpg

Posted: **Fri Oct 05, 2007 2:04 am**

You do need the direct path to the image from the cam. ZM does not parse html.

Oh...Thanks very much!
