You may recall that I had to install that in order for the camera (and camview stuff) to work with axis. It appears the hardware version couldn't do the pipeing redirects because while it said in the setup screen that data was flowing at x frames per second, it never got to the screen. I have not yet made a mount for the camera as this one doesn't have that nice cylindrical shape that would have fit in a 30mm scope mounting ring. I am considering and alu angle mount, machined away so the lens can see thru it as there is not another face of its over sized case that is flat and square to the front face. It will take me remembering to get a length of 1", .125" thick, alu angle when I am next near Tractor Supply. Its update rate on screen is also something on the order of 2 to 3 seconds, boringly slow. I assume its the huge disparity and the data decimation needed between the 640x480 needed for the axis window (and further shrunk to fit the actual screen resolution at whatever scale axis is presently using), and a camera whose native output is around 2700x2300 as its a full 10 megapixel camera. Raw pictures from it are stunningly sharp and about 20 fps. It seems to me this data destruction could be done much more efficiently by just taking the 640x480 out of the center of its F.O.V. & ditching the rest. Or am I missing a switch value in the initial setup. It is currently preserving the cameras whole F.O.V. while reducing the data rate to 640x480. I could also get 1/4" closer to the spindle centerline IF the flip module could turn it 90 degrees. That is of course part of the delay as its at least 2 full frames delay to do that flip. Any help in either of those regards would be appreciated, a lot. Cheers, Gene -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
