I was aware of the email address, but I admit I have not sent anything there -- but, my RSMs and Sales Directors are well aware. :) Your point about "proper channels" is probably spot on though.
We have discussed the Arecont angle before, and while I know they have had issues in the past, we've had phenomenal luck with the G2 line. However, we haven't brought them in to ACC before, and I know that's where you saw the issues. My point with this is that I would want to see Avigilon actually support these cameras, assuming it would only take small changes to ACC for them to be fully-supported. They are supported in such a wide array of other platforms, I can't imagine they are so specialized that ACC can't handle them.
Amazing that your call-out regarding tilt on domes is one that I just shared with them the other day. It's bad enough on the standard H4 domes (~9-degrees), but on the IR versions, it's totally unusable with a 30-degree (!) tilt. That's not the issue I'm working on right now, but it's definitely an issue nonetheless.
The B1 version of the HD camera is very nice, and admittedly covers a huge range, which is something that nobody else has to my knowledge, so I have to give them props there. But, I'm actually looking for something with a longer lens -- more than in 100-150mm range, where they cap out at 84mm.
I will send you a message separately regarding the mounts -- feel free to respond when you're able.
