See that security camera up there? It's probably from AD Holdings. AD Holdings (the "AD" stands for Anglo Design, but the company does business as AD Group) supplies closed-circuit TV (CCTV) systems, digital video recorders (DVR), and video smoke detectors (VSD) to public and private industries around the world. Its TransVu mobile CCTV system monitors school buses and public transportation systems, while SmokeVu can detect fires on airplanes and underground commercial tunnels. AD Group is also the parent company of AD Aerospace. AD Group is comprised of 10 subsidiaries.
