Technology advancement has brought in so many benefits more so in surveillance and security gadgets. One of these gadgets is the night vision CCTV. This is used to observe proximity areas, even in low light conditions. The CCTV is designed to create images through thermal imaging, infrared illumination and low light image enhancement.
• Low light image enhancement
This involves image intensifier that amplifies the available light to create images from energy of the electrons of the object being observed.
• Infrared illumination
Infrared rays are used to illuminate the object under observation where the CCTV is installed with an infrared red source and illuminator to help create an image of the illuminated object.
• Thermal imaging
This works on the fact that all objects emit energy in the form of radiations. The night vision CCTV system uses a thermal imager that collects the radiation emitted and creates an image.
When deciding on which night vision CCTV to install, consider the resolution, sensitivity and lens focal length.
