Glazing unit security system

A motor vehicle glazing unit security system comprising:

• multiple glazing units each mounted in a door and having a tempered glass pane movable between an open and a closed position and having an area hidden from view in both the open and closed position, and an electrically conductive strip of frangible cured polymeric material self-adhered to a surface of the glass pane in the area hidden from view, the polymeric material being electrically conductive ink;
• electrical connection means for electrically interconnecting the conductive strips;
• and
• security means electrically connected to the connection means for sensing and responding to a loss of electrical continuity of any of the conductive strips.
