The notable trend I see is some smaller manufacturer members downsizing or leaving the industry. That's a trivial part of IPVM as a business but I do see it as a 'canary in a coal mine' for what is happening with the manufacturer market.
End users are probably gaining share of IPVM membership but I think that's more of them finding out about IPVM later than a DIY trend bringing us members. Also, I don't think there's a dramatic increase in DIY among businesses, I think it's more that they are paying less to integrators and manufacturers per unit / camera / door.
Integrator memberships are fairly stable / growing.
In terms of membership, it's roughly 60 / 30 / 10 - integrators / installers, manufacturer / distributors, end users.
As for the around the world report, I don't see any terribly notable shifts in geographies. The strength of the US dollar has made IPVM more expensive for many professionals in other countries and we have had a few people make note of that, but that's not been major.
Part of what IPVM is becoming is based on what we plan to do. For now, I've been more focused spending time with my family than expansion. We are publishing more than ever (tests, news, etc.) but marketing and outreach is a low priority.
