Read Camera Image From WebCamera

The way to read image from WebCamera is easy. You can type http://(WebCamera URL)/xyz.ws0 to get image of camera 1. The key point is that *.ws0 tells WebCamera to send image camera 1 and *.ws1 for camera 2, etc. The file name "xyz" is any name you want. We name file name to combine date and time in WebCamera home page. You can name the file accord with your need. For example, you can send a HTTP request: 

http://x.x.x.x/camera1-2001-10-05-08-30-00.ws0
http://x.x.x.x/camera2-2001-10-05-08-30-00.ws1
http://x.x.x.x/camera3-2001-10-05-08-30-00.ws2
http://x.x.x.x/camera4-2001-10-05-08-30-00.ws3
Those four requests will read images of camera 1, 2, 3 and 4. The file name will help you to manage images.

The Script in WebCamera Home Page

The script in WebCamera home page is written with Java script. It sends request to get camera image every time interval and maintain 1/4/16 views. For example, this page will refresh image of camera 1 on 210.242.175.22 every 500ms: 
<HTML>
<HEAD>
<TITLE>WebCamera Example</TITLE>
</HEAD>
<SCRIPT>
var i=1;
function Init()
{
  setInterval("Refresh()",500);
}
function Refresh()
{
  document.Camera.src="http://210.242.175.22/"+i+".ws1";
  i++;
}
</SCRIPT>
<BODY onLoad="Init()">
<IMG NAME=Camera WIDTH=352 HEIGHT=240>
</bODY>
</HTML>

There are some examples can be ran in Netscape Navigator and Microsoft Internet Explorer:

ex-1-1.htm Refresh one camera every 500ms.
ex-1-2.htm Refresh one camera with full speed.
ex-2-1.htm Refresh four cameras every one second.
ex-1-2.htm Refresh four cameras with full speed.
ex-3.htm Demo example for special image layout.

Localize Web Pages Inside WebCamera

You can find all web pages in the directory "www" when you use FTP to connect to WebCamera. Download all *.jgi and relpace the English string in the files to your local characters. For example (this line is from permit.jgi): 
<td bgcolor="#99ccff" align=right>User Name</td><td><input type=text name=id size=12></td>
You can replace "User Name" with "Account" or local characters. There are JGI files:

main.jgi The home page of WebCamera
permit.jgi Login page
config.jgi System configuration page
security.jgi Security setup page
tunning.jgi Fine-tunning page
recevent.jgi View record page
datetime.jgi Set date and time page

And you can modify any JGI files to add your links and pages.

Control Strings in JGI Files

All control string in JGI files will start with the "~", and WebCamera will interpret the control string. For example, the "~hour" will be reaplced with the current time when WebCamera read it. The control string should be placed in single line. This line "Cuttent time is ~hour and..." should be written like this:

Current time is
~hour
and...

Thete are control string that WebCamera will replace them with tags for table and form.

The "value" are the value of parameters.
