A brief survey of the theoretical, physical, and psychophysical background of surveillance, the basis of security, is given, especially, in those cases when the signal carriers are electromagnetic waves. The concept of flat cylinder perspective (FCP) is introduced, allowing an undistorted 360-degree panoramic view. Technical considerations of designing such an optic, called PAL, satisfying these criteria are presented. Examples are given regarding how to use some instruments based on PAL-optic in surveillance and security related panoramic inspection tasks.
