Security module
First Claim
1. A security module through which personnel must pass when traveling between zones at opposite ends of said module, comprising a housing having a plurality of spaced apart interior facing side walls extending intermediate an entry end adjacent one of said zones and a exit end adjacent the other of said zones, personnel sensing means mounted within said walls for generating signals in response to the presence and absence of personnel within said module, said sensing means comprising infrared signal transmitters in one of said walls for directing infrared energy toward the other of said walls, and cooperating infrared signal receivers in the other of said walls for receiving said energy unless precluded by the presence of a person in the module, means defining grooves within said walls for receiving said sensing means and said walls comprising a composite structure having interior facing wall surfaces including opaque sheet material over said wall surfaces and covering said grooves for concealing said transmitters and receivers respectively but permitting said energy to pass therethrough.

Abstract
A security system including a security module positioned so that personnel traveling from a first zone to a second zone pass through the module for identification and verification of access. The module includes a card reader on one wall for reading an identification card inserted by the personnel, a scale for weighing personnel within the module, sensors for measuring the height, girth, position and direction of movement of personnel passing through the module, and video cameras for viewing such personnel. Information relating to whether the card is used properly, whether the card is correct and valid, whether issued to the person carrying the card and whether the person should be traveling between the zones at that time is determined and alerts provided when violations occur. The scale includes a floor plate suspended within the module. The sensors are infrared detectors connected within panels forming the interior walls of the module which are removably connected to the frame of the module by rods carried by the frame and selectively rotatable for receipt and locking within slots in brackets secured to the panels. Video cameras are concealed within end caps at the entry and exit ends of the wall on which the card reader is mounted and unobtrusively view personnel through one-way mirrors.
