Hi,
If you using the Foscam to display an image on a web page, you will need a server side script to enable this, (I can post up the one I use if that helps) and its a bit of a faff to setup, image and reliability are good.
My other camera which is excellent is a Hikvision, this would be my preferred choice and can ftp directly to be published on a web page.
Plenty of advice on both camera types in the forum.
