Video management software companies entering access control is a growing trend.
One of the first to do this was Genetec, who now has a long history in both video and access. Indeed, they market their Security Center as a 'unified security platform' rather than 'just' a VMS or an access control system.
In 2013, Milestone jumped into access control at the same time as Axis. Indeed, Milestone's first access control partner is Axis.
