We did some preliminary testing with it vs. the Speco, but not the more extensive tests in the report. It wasn't intended to be a low light shootout, but a one off test of the Speco Ultra Intensifier and its issues.
And to be clear, at ~1 lux, the 2125 performed similarly to the Ultra Intensifier (when set to non-blurring settings). At lower lux levels (~0.1 lux), it was dimmer, nearly black, though Speco provides only minimal detection at that light level, also.
Do we know of any other models of cameras with that large of an aperture (f/1.0)? Should one expect a very shallow depth of field? Are we trading light sensitivity for lack of depth of field, which may end up causing its own issues?
The Speco Ultra Intensifier actually uses an F0.94 lens, and we did not observe any practical depth of field issues. I believe that since these cameras use wide AoVs (90°+), you'll see decrease in details from PPF dropping at distances well before you'd see issues from depth of field, in most cases. That's been our experience.
There is White LED Illuminator on the camera. By factory default, it is turned OFF. I had to manually turn it ON, but never comes ON when I feel that it's too dark and should illuminate. I wasn't given a manual and I figure calling into Hikvision USA would be useless since they never launched it yet.
