Target Accuracy with Enhanced Situational Awareness
Perimeter security with a defense-in-depth strategy is a typical solution for many facilities when viewed under the new light of global terrorism and sabotage. Perimeter defenses include fences, barriers, guards and security patrols. A strategy of defense-in-depth for critical infrastructure facilities typically places several layers of sensitive intrusion detection sensors in an illuminated buffer zone between an outer perimeter fence and actual facility equipment. Such intrusion detection devices include infrared imaging cameras, short-range radars and laser radar (LIDAR, or LADAR).
The most effective perimeter-intrusion detection systems use multiple technologies to increase the probability of rapid detection and low false alarm rates under a range of atmospheric and lighting conditions. Sensors Unlimited's short wave infrared (SWIR) cameras offer considerable benefits at facilities where atmospheric condition such as rain, fog and mist are common. These conditions typically blind visible cameras, but Sensors Unlimited's InGaAs SWIR technology is capable of seeing through all but the most severe conditions to provide highly accurate images. Sensors Unlimited's SWIR cameras also provide exceptional low light performance, essentially providing high quality images in all but total blackout conditions.
The left side of the image below is visible imagery of a landscape by haze. The right side shows clear SWIR imagery of a targeted spot on the scene.
Watch the video below for a more detailed look at the advantages of SWIR cameras in foggy or hazy conditions.
Many SWIR camera capabilities are considered sensitive. If you would like to learn more about SWIR capabilities for the military, you can register at a special web site, www.swirconops.com. You must be a US Government employee or a USG contractor and be a US Citizen to access this site.
