What bothered me:
Unfortunately (currently) not compatible with QNAP (SurveillacePro v3).
I got me a lot of apps (iOS) - downloaded partly charged. No app has support all the camera functions - did not want to then invest even more (may well be that there is an app that does this)
Time Synchronization: summer / winter time, sync via NTP (hourly) - Daylight Savings Time has never worked, at least not if you have entered everything correctly (with fake doable, but I will not)
The Web interface is absolutely carelessly and the German translation of bad (there was but a newer firmware that pointed only in the area to improve - not tested). But that alone would not have mattered to me ...
In sum me the handling is simply not pleased with this camera and they went back with a heavy heart, because as written already beginning: The image quality is absolutely top!
For a new version I would also have a Mini Speaker (built-in) wish - for bi-directional communication.
edit: Did now opted for this alternative: PSC = 1 - APPs there, QNAP compatible and image quality should be ok (not FullHD)
