The different between Black Beam Night Vision technologies against Infrared Image & Low Light Night Vision techniques are Infrared Image Sensor sense only the warm outline of human body and the object while Low Light Night Vision requires certain level of moon/star light illumination or else it can see nothing. With the help of enhance illumination, infrared is able to view the object better and further, but at the same time it also expose to risk because enemy can spot the infrared easily thus it is not possible to use Infrared Image sensing camera for hide out/ under cover surveillances requirement.
