It’s been exciting to see infrared sensor technologies develop over the years. Early infrared sensors, which can provide better images than conventional CCTV cameras especially at night, were too bulky and expensive for most organizations to employ. As outlined in this article, improving technology has made infrared technology more widely available.

Just how much is the popularity of electronic access control systems growing? This article provides some insight and states that they are one of the fastest growing sectors of the security industry. Biometric systems and smart card technology are among the developments spurring this growth.
There’s more to effective access control than just putting up some fences, cameras, and security lighting. As this article outlines, access control also encompasses determining which zones of a facility require protection and what level of protection each zone requires. Access to these protected zones almost always involves a method of identifying personnel, and there are many different ways of doing this. Here are two main categories.
One of the most promising developments in biometric identification has been iris recognition systems. As this article explains, this technology makes use of the unique pattern of specks in each person’s iris to verify the identity of that person. Iris scanning has been used on a limited, experimental basis in both the U.S. and Europe and offers many advantages.
