Welcome to Security Camera Integration Wiki


A retinal scan is performed by casting an unperceived beam of low-energy infrared light into a person’s eye as they look through the scanner's eyepiece. This beam of light traces a standardized path on the retina. Because retinal blood vessels absorb light more readily than the surrounding tissue, the amount of reflection varies during the scan. The pattern of variations is digitized and stored in a database.

Retinal scanners are typically used for security authentication and identification purposes. Retina scanning has been utilized by several government agencies including the FBI, CIA, and NASA. However, in recent years, retinal scanning has become more commercially popular in access control systems, like those installed by NRSEC.

What is Video Standard?

Different areas of the world use different video standards. North America uses NTSC, Europe uses PAL and SECAM, South America uses PAL-M, PAL-N, PAL and NTSC. Almost every area of the world has a mixture of video standards. If your CCTV/recorder/camcorder support multi-systems, you can use either PAL or NTSC camera. With a multi-system video recording format, you expect an PAL tape to be reproduced as a standard digital PAL signal, and the same machine if fed with a NTSC tape will reproduce it as a standard digital NTSC signal. A multi-system interface recorder can also be expected to make a perfectly normal PAL recording of an PAL input signal, and a perfectly normal NTSC recording of a NTSC input signal. A NRSEC representative can provide professional advice in selecting the correct Surveillance security camera.
