CCTV: Night Vision Cameras

Today’s Eio post is on night vision cameras.


Night vision cameras fall under the larger umbrella of CCTV (closed-circuit television) cameras. They generally serve the same purposes as other CCTV cameras, being that they are cameras to transmit a video signal to a specific place, usually viewed over a monitor. Night vision cameras are most often used for video survelliance purposes.

Night Vision Cameras

A night vision camera, which falls under the night vision devices (NVD), is an optical instrument that permits observation, photography, and video recording in extremely low-light or no-light conditions. It records video in levels of light approaching total darkness. These cameras are most often used by the military, police, other security forces, and are also available to civilian users. Most civilians do not use these cameras for recreation and wildlife observation.

In terms of the technology and how night vision cameras operate, Wisegeek says this:

There are two primary technologies used for a night vision camera. The first, and most common, is a photomultiplier tube, or “conventional night vision,” operating in the near-infrared frequency range, picking up light waves about 1 micrometer wide (human vision can only see light with a frequency between 0.4 and 0.7 micrometers). The second is thermal imaging, which allows a night vision camera that can take pictures even in cases where light is absent. This is because thermal cameras can see the electromagnetic radiation released by blackbody heat that emanates from every physical object. The newest types of night vision camera use a blend of both technologies.
