Re: Doesn't matter yet
"Unfortunately, IE is still required for many web sites and web connected devices (security cameras anyone?)."
I can tell that even today there are brand new cameras and DVRs which only support IE as the browser (with some crappy and shady plugins).
Most network cameras support some form of JPEG, MJPEG (or better) retrieval via HTTP or RTSP. In those cases you can use VLC, iSpy and other software to view the feed.
Of course there are plenty of old, proprietary IP cameras from an era when standards like ONVIF didn't exist. Those cameras probably are of VGA resolution at best.
