Check out this video from the Friends of Itamar posted December 23, 2010, promoting emigration to the settlement. We are introduced to the "Control center" in the West Bank settlement. At 7:55 the narrator describes the video surveillance system (camera zooms in on a tower) attached to the alarm system:
"Camera surveillance system instantly monitored even at night"....
"the surveillance sensors signal a alert of a potential terrorist trying to break thru and the exact location of the infiltration is fed to the computers and the remote control camera is zoomed in to the exact location to track the terrorist"
Was this system operational on March 11, the night of the murders?
