SWIR Cameras and Accessories in Security & Surveillance

Infrared security cameras use infrared LED (light-emitting diode) lights located on the outside of the camera lens, this is so that the light can capture the images even areas with little to no visible light. The infrared measures the heat emitted from objects in the focus range of the camera. That's the biggest advantage of IR security cameras.


GHOPTO'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 GHOPTO's InGaAs SWIR technology is capable of seeing through all, including fog, rain and mist but the most severe conditions to provide highly accurate images.




InGaAs Image Sensor's Advantage Compared with Thermal Imagers

InGaAs SWIR imagers are complimentary to thermal imagers when it comes to vision enhancement and low visibility in poor weather conditions. Imagery in the SWIR is similar to visible imagery, in that it senses reflected light, thus interpretation and scene analysis is improved over thermal systems. 


One of the unique aspects of SWIR imaging is the unusual way in which natural and artificial materials appear in the SWIR part of the spectrum.Translating this to a border crossing or checkpoint situation, one can assume that anyone wearing a disguise as they approach the border has some form of criminal or even hostile intent.
