LG Electronics has introduced its IrisAccess 3000 for door control use. The system does not scan the iris image but captures it. Also the illuminated infrared light is safe to humans and meets the eye safety standards of the US and European markets. In addition, identification is perfectly performed even when the person being scanned is wearing spectacles or contact lenses. The recognition process is performed from a distance of 3 to 10 inches and is therefore a noncontact process.
An enrolment optical unit, EOU3000, is placed on a desk or table adjacent to the server PC. EOU3000 contains all the elements necessary to initiate the enrolment process, illuminate the iris and acquire an iris image. The remote optical unit, ROU3000, is installed adjacent to the door that is being controlled. ROU3000 is composed of two parts, the optical imager with the front enclosure and the rear enclosure. After the rear enclosure is mounted on or recessed into the wall adjacent to the controlled portal, the optical imager with the front enclosure is mounted within the rear enclosure. The ROU3000 contains the elements for iris image acquisition and also provides voice message and light indication whether the user is recognised or not.
The identification control unit, ICU3000, is installed on the wall inside the protected or controlled area in order to discourage tampering with the computer. This unit creates an IrisCodeTM from the input iris image through ROU3000 and compares this IrisCodeTM with pre-memorised iris records. If a matched IrisCodeTM is found, ICU3000 generates a signal to open the door. Basically, ICU3000 can control the access of two doors with one frame grabber board (FGB) and one door interface board (DIB) inserted. By installing another FGB and DIB, ICU3000 can control up to four ROU3000, and therefore the access of four doors. A frame grabber board captures the analog black and white iris image and converts the analog iris image into the digitised format to process in the server PC or ICU3000.
The door interface board checks and controls the releasing and locking of the door being controlled and also provides the interface between ROU3000 and the motherboard in ICU3000. An optional replaceable door interface board can interface with Wiegand or RS422 card reader system and with access panel.
The Server PC serves as Super Server, server, enrolment station, monitoring station and management station. These roles can both be performed via one PC as well as performed via separate PCs. Super Server transfers database records from one server to the other server by request. The server manages both stations and ICUs. The enrolment station performs the iris registration with EOU3000. The monitoring station monitors the status of ICU, ROU, EOU and doors being controlled. The management station not only maintains the old and new database of users but also allows downloading of necessary data to ICU3000.
