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.)

Die Kamera wird auch verkauft unter dem Label von: LogiLink Longshine

Die neueste Firmware (derzeit 1.34) bekommt man aber nur bei Edimax

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)

   <?

     $pass = "xxxxxxx"; 
     $ip = "aa.bb.cc.dd";

Uff! Finally, habs ichs rausgefunden:

Vom Hersteller EdiMax gibt es auch die Software als OpenSource 3)

Mit einer URL alle Parameter verstellen: http://admin:1234@192.168.2.3/form/camera?resolution=0&quality=3&framerate=25&frequency=0&autoexposure=ON&b_value=35&c_value=50&s_value=50&h_value=50&w_value=10&enet_source=camera_left.asp

Options are as follows:

 Resolution: 
 0 = 640x480 
 1 = 320x240
 3 = 176x144
 
 Quality: 
 3 = Highest 
 = High
 = Normal
 = Low
 = Lowest
 
 Frame Rate: 
 30 = 30 frames per second (FPS) 
 25 = 25 FPS 
 20 = 20 FPS 
 15 = 15 FPS 
 10 = 10 FPS
 5 = 5 FPS 
 3 = 3 FPS
 1 = 1 FPS
 
 
 Frequency: 
 60 = 60Hz (this works best in the night or indoors in incandescent light)
 50 = 50 Hz (this is for fluorescent light or night)
 0 = "Outdoor" mode (this works best during the day)
 
 Auto Exposure: 
 ON /OFF 
 
 Others values are listed below, but the defaults have been noted to work fine.
 Black
 White
 Brightness
