Monitor state of an item and trigger some action if state changes

One solution would be to use a dynamic sitemap (https://github.com/openhab/openhab/wiki/Explanation-of-Sitemaps#dynamic-sitemaps)
You could have a frame that contains an image widget for the camera and the button. The frame's visibility would be tied to the doorbell item. Put this at the top of each section of your sitemap.

@madon , what do you think about the solution proposed by @digitaldan ? I'm always eager to fulfill user needs, but navigation controlled from openHAB is something which is not specified in openHAB API. And I'm not against Tasker integration, I just don't have enough time resource to do it myself :-)

What about GCM (sendNotification) and a custom prefix like "intent://" which would trigger an intent. We should discuss this with the ios developers to get a similar user experience.

Monitoring of state changes on a end user device, even with wifi, would be a bad idea to me as the server push is more efficient.

Intent to do what? :-) The problem here is that we don't have a mechanism to address certain sitemap page other then URL which can be different in different environments. Anyway, if current options for doing that doesn't fit the task this should be discussed on openHAB level I think.
