Aztech: blinking lights on the cameras, but couldn't find the demo pc for viewing. Comparison info said that 7838 can only mount on ceiling and uses 4.2mm lens, while 7837 can also mount on wall and uses 3.6mm lens.
But I think all 7838 are now supposed to use 3.6mm lens?
The f1.4 aperture on these lens means there's a smaller sweet spot with acceptable focus And, the 7833 is gigantic!
Yet it's optical zoom really is just slightly more than 2x. harder to do side-by-side comparison because the dlink demo wall is far away.
