I can't speak for the ReefKeeper, as I have an Apex. However, keep in mind that while you may hear of people having webcams (actually IP cams) on their Apex, all this really means is that the Apex Dashboard website has the IP camera address linked to it so that the camera displays on the Dashboard page. The Apex itself isn't actually attached to the camera, nor does it give two flips about the camera. It's just handy to have the camera show on the same page as the Dashboard.
If DA doesn't have something like this, it's just as easy to setup an IP camera to be viewed in the browser or smart phone independently of the controller.
