So these guys have been ramping up their sales force in N. America and do have a pretty solid product for the Enterprise. Their key solutions are the analytics (which are solid) and their Enterprise Manager, so for the larger systems, they will absolutely expand their customer base. I hear that they've actually got some pretty large customer wins that will likely be announced soon that should validate all that.
I don't see them really targeting the smaller market at all, and the medium market will likely be limited to those opportunities that really need the analytics. And while they do support a lot of cameras, Axis do tend to be their best supported camera partner.
Sounds like you'll be in great hands for your project.
