See all those “Not Working” reviews? Answer here.
I was just about to join the “not working” bandwagon but finally found the solution: updating your camera’s firmware. I’m not entirely sure when DSCam stopped working correctly for me but yes, the other reviews are mostly correct: a spinning icon on a black screen despite a correct preview image. The issue either began with iOS 8.1 or when I upgraded to Surveillance Station 7 (which is still in beta at this time). I have a Foscam FI9828W and found that the company has frequent firmware upgrades. This was what was needed so please be curtain you have the most up-to-date firmware installed! Only 3 stars as I felt that the Synology software could have either detected as issue or suggested this as a solution more visibly.
