Q1: I would like to know if there is a way to view IP cameras via browsers other than IE. (such as Opera, Firefox, Galeon, etc.)

Our 2000 series and 7000 series (except IP7137/IP7135/IP7131/IP7132/PT7137/PT7135) products support Firefox viewing.

For others models, please refer to Display - Q10.

Q2: I have a web site and I want to design my own homepage to replace the current one. I want to make it so anyone one can see the image from my website. How do I do it?

Prepare an auto-refresh homepage like the following example. The URL of the image is

http://"IP address of the Network Camera"/cgi-bin/video.jpg

Modify the IP address according to your network camera. Define the refresh interval according to your network bandwidth for best result. If the refresh rate is too fast and there are a large number of visitors, this may overload the network camera and slow the response.

****** Example homepage begin ******
<html>
<head>
<title>Example - auto refresh</title>
</head>
<body background="/pic/wallppr.jpg">
<p align=left>
<font size="7" face="Comic Sans MS" color="#FF0000">
Network Camera Demo
</font>
</p>
<p align=left>
<!-- Begin of scripts to auto refresh the image. Change the IP address in the image URL and refreshrate if necessary. //-->
<script language=javascript>
var image="http://192.168.0.203/cgi-bin/video.jpg"; //IMAGE URL
var refreshrate=5; //SECONDS BETWEEN REFRESH
var imgwidth=352; //IMAGE WIDTH
var imgheight=240; //IMAGE HEIGHT (NTSC:240; PAL:288)
function refresh(){
document.images["pic"].src=image+"?"+new Date();
setTimeout('refresh()', refreshrate*1000);}
document.write('<img src="'+image+'" height="'+imgheight+'" width="'+imgwidth+'" name="pic">');
if(document.images)window.onload=refresh;
</script>
<!-- End of scripts to auto refresh the image. //-->
</p>
</body>
</html>
****** Example homepage end ******

Q3: What is the bandwidth requested for double size and 20 FPS?

The bit rate is involved with audio and video setting and the complexity of image. Please download the Calculator.exe tool.

The "Calculator.exe" is used to obtain the values of frame rate, video bit arte and audio bit rate of server.

The user can use the information for bandwidth evaluation and network deployment.
