Hmm. I've got 3 AV8185DN's hooked up to my server running ExacqVision VMS (Start). I'll have to check the firmware version, but the cameras less than 8 weeks old.
When I started Exacq the first time, it immediately recognized and connected the 8185s.
The only issue I've had is the slow reconnect time that's been discussed elsewhere. Even that's only been an issue if I make changes to the camera settings using something other than Exacq (e.g. the AV100 software or the camera's built-in web interface).
