I'm not a Bosch dealer. I don't sell anything to anyone, but I do test a lot of cameras.
The only Bosch low light unit I have here at the moment is an original 720p Starlight. It's a very good low light camera, but at half the resolution of the Darkfighter. I have some of the 8000 series teed up for loan in the first week of August to shoot out against some other new stuff from another manufacturer.
I've got cameras from a few manufacturers (Bosch, March Networks, GBO, Axis, Hik, Avigilon) here at the moment. I just expected the Darkfighter to be as good as its price suggested it'd be. It was aimed at the Axis/Avigilon/Bosch market and marketed as such, but it's just not there. I had serious ONVIF compatibility issues, firmware glitches and other issues that are just not good enough for a camera marketed at the $1000 price point. I don't mind the Hik 2-line stuff, because when you are only paying a buck fifty for a camera you get a camera worth a buck fifty and you don't have enough skin in the game to be worth complaining about.
I don't currently have any comparison samples I could share because of the nature of the target areas. When I next do some tests I'll find a public park or something and see if I can knock up something anonymous enough for the internet.
