Abstract
A security system comprises a plurality of viewing zones or windows (4, 5, 6). Each zone includes a lenticular device (4a, 5a, 6a), the lenticular devices being constructed such that at different first angles of view or first ranges of viewing angles, the lenticular device in each viewing zone generates substantially the same first image. The angles or first ranges of viewing angles of the lenticular devices practically do not overlap.
