Why Is IPVM Is Publishing Articles About Access Control?

Curiosity has made me ask this question and maybe I've missed something. I normally lurk around and read the reviews to gleam information about IP video systems.

IPVM has been doing a great service with the tests, articles and surveys about IP Video, but seems to stray away from the core subject when they talk about access control when it's not related to IP cameras or VMS systems, such as the latest tutorial on schedules and levels. Great information but outside of the core of what IPVM is. IMHO. So why?
