Hopefully I'm following, and maybe I'm not, but the Atlantean device that Batman gave to Aqualad was an Atlantean bug. Like a wire tap or something. Tech used to spy on the surface world, specifically Batman, Waynecorp facilities, and so forth. The sort of thing that would be used to facilitate extensive research on the Batman and his "bastard" children. So no more glorious 1080p HD footage of the Bat-dong in the Bat-shower.
