During night time, the human eye is limited in the sense that its vision only reaches to several feet. This is where night vision cameras come in to help protect the area by efficiently monitoring the displayed clear images of even darkened areas. When the discovery of infrared brought forth the invention of night vision cameras, then the types of cameras have been discovered which can display an image even in darkened areas, thus there are several practical applications of night vision cameras have been discovered.

Perhaps the most popular night vision cameras are those that use near infrared illumination technology. Its popularity stemmed from the fact that it can produce clear and quality images at minimal cost. This type of night vision camera utilizes another device called the infrared illuminator. These infrared illuminator devices emits a bright infrared light which is invisible to the eye, but can be seen and detected by a night vision camera.

Oftentimes in a LED array configuration, these illuminators have between twenty five to thirty, high intensity, infrared emitting LED lights even when powered on, this infrared illuminator may appear to be doing nothing at all when viewed with your naked eyes, it is in fact emitting a low frequency light which is very bright when viewed through a night vision camera with near infrared technology. If you try to point the illuminator at a dark area and view it through the camera, it would return a very vivid monochromatic image. In effect, these infrared illuminators act like an invisible spotlight which “illuminates” a certain area for the near infrared cameras to see. When infrared camera and illuminator are combined it is often integrated with intelligent scene analysis and video motion detection devices to further enhance its monitoring capability. In sensitive areas, it helps the security personnel to guard low light monitoring system.

This type of cameras is extensively used in high risk areas such other sensitive buildings and research facilities in order to monitor the parameter.
