There is no "video" tag in what you show.
Are you looking for
<div id ="video-area-wrapper">
??
strcmp() and regexp() come to mind.

The specifications list differs from the documentation, sigh.
The video streaming in MS Windows browsers is handled by an ActiveX control. If the camera detects you are using firefox or netscape as the browser, it switches to streaming Quicktime; I checked, but there is no present support in MATLAB for decoding streaming QuickTime.
The camera supports rtsp, but it is not clear whether there is any way of using that. There is a _possibility_ that you might be able to use the MATLAB File Exchange contribution mreader() for this; see http://www.mathworks.com/matlabcentral/fileexchange/8028-mmread and look through the remarks to see what someone tried (but did not succeed on.)
If you look at page 62 of the user manual http://www.vivotek.com/downloadfiles/downloads/usermanuals/ip7161manual_en.pdf then you will see that you can switch from MPEG-4 to "JPEG", which is "motion jpeg". Other parts of the document describe this as if is a simple "server push" of JPEG images, and say that firefox and netscape supports it but IE does not. I have seen "motion jpeg" in other contexts and I am not at all certain that it is the same thing -- e.g., videoreader supports Motion JPEG 2000 files (not streams) but not Motion JPEG. Server push is a relatively simple technology that I would have thought was indeed supported on IE.
More details on taking snapshots are shown on page 146.
So, where have we got? Not much further than before. Two possibilities; rtsp (I suspect will not work), and pulling continual JPEG off (might work, but urlread would not be happy about it because the technology works by always saying there is more information to come and urlread wants to read until the end of the information before returning.)
Best lead so far? Streaming to a different process and pulling off the frames from there. Which is where we already were before the thorough reading of the documentation.
