NetCam XL

Keep in mind that the overhead of FTP doesn’t allow for the same 

update rates that you see when accessing NetCam directly with a browser. It 

is safe to say that FTP restricts 320x240 uploads to once every 1-3 seconds, 

even on a DSL or cable connection. 640x480 images will probably not 

upload faster than once every 3-10 seconds.

Default: 

30

Upload Window

NetCam can upload images 24 hours a day, seven days a week, or you 

can set whatever time window and days of the week you like. Use military 

time for the beginning and ending window times.

Example: You can configure NetCam to only upload Between 07:30 

and 18:30 only on Monday, Tuesday, Wednesday, Thursday and Friday.

How do I display the live image on my web site?

The simplest way to add the live image on one of your web pages is 

with the image tag: 

<img src=”netcam.jpg”>

To see the current live image, the visitor would have to hit the refresh 

button. This reloads the web page and will display the current live image, 

assuming a new image has already uploaded.

You can add a meta tag to the 

<head>

 section of your web page 

that  tells  the  browser  to  refresh  the  web  page  at  specified  interval: 

<meta http-equiv=”refresh” content=”30”>

If you prefer a slicker solution that doesn’t require refreshing the whole 

page and visibly redrawing the live image, StarDot provides a free Java 

applet. You can download the Capture Client Java applet and instructions
