Yup - they all seem to add up the horizontal pix and advertise that number. I suppose that makes reasonable marketing sense, and If the sensors are fixed, it makes more sense. However, the new Avigilon 3 sensor and 4 sensor panoramic cameras have independent cameras within the dome, with certain physical aiming restrictions. With each being a 3MP camera, they rightly call refer to them as a "multi-sensor" camera.
The part numbers are a little confusing - to me, MH means Multi-Head so maybe MH should be MS, but they didn't consult me.

Matt, you should be able to get a single 6MP stream out of that camera by using Mode 2*
*Whatever the hell that is ;)
Samsung seems to be marketing their fisheyes properly. The SNF-8010 has a 6MP sensor but is marketed as a 5MP camera.
Matt, have you tried setting real-time mode:
its supposed to only output one high-res stream then.
Thinking about it though, even if you get it to give you a 3072x2048 stream, I don't see how it could have any more actual information than a 2048x2048 one.
Barring an elliptical lens or non-square pixels, the image circle is just that, a circle, which will be inscribed in a square. A circle inscribed in a square takes up pi/4 of the area, or around 80%.
So if you get a 3072x2048 stream I would think one of the following three things is happening:
- Stretching the 2048 to 3072 in the horizontal.
- Asymmetric letter boxing.
- Image circle cut off on the top or bottom.
Net/net, a 4.2MP (2048x2048) stream, will contain the entire 3.3MP (80% of 4.2) image circle.
Anything else is BS or worse.
I could be very wrong of course, what do you think?
