Only real problem I have had is that most of the major software vendors do not list, or do not 100% support the camera as of yet.
I have tried almost all of them, so far:
BlueIris WILL connect and partially control the camera. PTZ Works, Presets work. Control of the IR leds and IR filter do NOT work.
Ispy, connects kind of, gave up fiddling with it.
I am sure all of them WOULD work 100% if I had better knowledge of the camera and the software package.
SUNBA has been very responsive to answering any questions I have had. Just be aware to run the camera at the highest resolution, you will need a good PC.
With the supplied CMS software, I was getting a 2 second delay in PTZ movement on my laptop. Tried it on a friends pc with an Intel I5 processor and it was more instantaneous.
Night vision is phenomenal, very clear images.
Have it running now with IPTlapse to provide images to my web page and create time lapse movies.

Have to tweak it a bit more. I have noticed a blur I get on my images, I am sure it is on the lens or a reflection from the lens or the glass in front of it.
it is NOT on the out side.
