Someone has made some errors in describing the actual specs;
2.1Million Pixels is 2.1 Megapixels not "Gigapixels" as can be evidenced by the "output image" - max 1920 x 1080
4.7-94mm lens is 20x adding 4x digital zoom actually makes 24x which could be misconstrued as 80x but not 240x
So actually its an expensive 2.1mp PTZ considering it doesn't use a slipring and is limited to 340 degrees rotation.
It is also limited to 15fps @ 1080p.
Yeah, this is ridiculous. On the other hand, who is the company?
They make another reference to 2.4 Gigapixels at the bottom of this page - so it does not seem to be an accident. Presumably they mean that if you take a 2MP PTZ, zoom in, and pan / tilt over a 260 area that it will cover or be equivalent of 2.4 GigaPixels. Obviously, under this logic, any modern HD speeddome would qualify and yet it would be pointless anyway.
On the other hand, maybe these guys are just trying out for Avigont's marketing team?
