Interestingly, Amcrest just released a firmware update yesterday night and now the MJPEG override is no longer happening on the Main Stream.. maybe they're watching us.. hehe..
That's good. I'm sure that override wasn't intentional and big bug to get fixed.
As far as I'm aware, MobiLinc works with all Foscam SD and HD cameras with Pan/Tilt/Zoom capabilities. If you find that none of the profiles work, let me know. Foscam cameras are usually pretty easy to connect to and work with to get updates supported.
