I have noticed that some manufacturers and OEMs do seem to provide support on IPVM. Milestone, in particular, deserves to be called out for active engagement as they have 1 or 2 folks post on here frequently -- and they have their own excellent support forums. FLIR does post occasionally when mentioned. Some of the distributors such as Savvy, Nelly's, and so on post as well. Are there any other manufacturers? Are there others that are simply Undisclosed?
IMO it is a credit to those manufacturers who are actively engaged with the end user and integrator community.
