I started in the early IT business and I saw how quickly that went to commoditization, disposibility and do it yourself. Now in the physical security world it will soon be the same. Hosted services along with cheaper and less complicated equipment to install, where you increasingly have to compete with electricians, locksmiths, audio/video & home entertainment, even handymen and a GLUT of IT services desperate to find more business getting into physical security.
Will the security integrator and consultant go away? No, of course not, but it's going to be an ever dwindling need and down to the level where they're just arms and legs running wire and mounting equipment. I currently work the integrator side. But the as the years go by, the more I want to get out of that side of things and get into something else like the manufacture side, R&D, maybe even that lowly distribution side (just kidding my distro friends). Or, for a large end user who wants a technology person focused on those technologies for management and logistics.
