MJPEG Webcam EDImax IC1500

Wiki for the EDImax IC-1500 IP Camera

Chinesische Billigwebcam mit WLAN Firmware v1.28 (Sep 14 2007 10:09:45)

Manual (engl.)

LogiLink

IP Address : 192.168.122.223

Subnet Mask : 255.255.255.0

Gateway : 192.168.123.1

DNS Server : 192.168.123.1

MAC Address : 00:1F:1F:17:F9:3E

Video Port : 4321

HTTP Port : 80

Ziel: mjpeg auf dem Browser

Problem: Keine Dokumentation. Webinterface soll das zwar können, aber JAvaScript zu schlecht.

Schaut gut aus, klappt aber nicht: mplayer http://admin:[password]@gerald.webhop.org:14322/IPCamPluginMJPEG.cab -vo gl

Webinterface ruft folgendes JavaScript auf:

http://gerald.webhop.org:14322/ipcam.js?v=200708241090

document.write('<OBJECT ID="IPCam_Plugin" CLASSID=clsid:b015b944-7316-49ae-ac84-acca9379ea32 ALIGN="CENTER" WIDTH="'+ ipcam_width +'" HEIGHT="'+ ipcam_height +'" Codebase="/IPCamPluginMJPEG.cab#version=1,0,9,2">');
document.write('<PARAM name="IP" value="'+ window.location.hostname +'">');
document.write('<PARAM name="Port" value="'+ port +'">');
document.write('<PARAM name="Login" value="'+ login +'">');
document.write('<PARAM name="Password" value="'+ password +'">');
document.write('<PARAM name="Code" value="'+ code +'">');
document.write('<PARAM name="Debug" value="0">');
document.write('</OBJECT>');

Das Plugin kann man mit

wget http://admin:[password]@gerald.webhop.org:14322/IPCamPluginMJPEG.cab

runterladen

Das Plugin ist von der Firma 'Edimax' und ist anscheinend für den IE geschrieben. Dort funktioniert es aber auch nicht richtig, der IE beschwert sich über Fehler auf den Seiten.

You can get images from your camera with my PHP script and a web server in the following form: Quelle2)

   <? 
 
     $login = "admin"; 
     $pass = "xxxxxxx"; 
     $ip = "aa.bb.cc.dd";

Uff! Finally, habs ichs rausgefunden:
