Night vision for security

A staple tool in any action movie is the night vision. Whether it is a set of goggles, a camera, or some other form of surveillance, the effect of that grey grainy image is astounding. Whether it is for sport, surveillance, or just for fun, any person can harness the power of such a remarkable tool with the purchase of a night vision item.  Night vision works in one of two ways: through image enhancement or thermal imaging. Image enhancement takes whatever visible light that is available and combines it with light lower on the spectrum that is unperceivable to the naked eye. This has the effect of illuminating the viewer’s surroundings. On the other hand, thermal imaging captures light from higher on the spectrum to create illumination. The light that is captured is the light emitted whe the object releases heat.  The decision of whether to opt for image enhancement or thermal imaging night vision is really a matter of personal choice. Image enhancement devices are more commonly used and easier to find. They offer excellent images, especially when used outdoors. On the other hand, no environment can be too “dark” for a thermal imaging device.  If you are considering a thermal imaging product you can evaluate the quality by assessing a few specific areas of criteria. The first is the device’s scan rate. A rate of thirty times per second is considered optimal and obviously anything above this is superior. The second consideration is whether you would like your devise to be un-cooled or cryogenically cooled. Un-cooled devises are easy to find, operate at room temperature, and run silently on a built in battery. Cryogenically cooled devises are more difficult to find, more expensive, and very delicate; but they do offer astounding image resolution. Night vision tools come in a variety of forms including night vision scopes, night vision binoculars, and night vision cameras. Night vision scopes are monocular tools that can be handheld or weapon mounted. This tool is best for specific item viewing rather than scanning. For scanning, the better choice would be night vision goggles, also known as night vision binoculars. These goggles can be either handheld, or worn on the head allowing for full mobility and constant use. Finally, night vision cameras are a necessity for any area at risk of a security breach. Considering that crime rates increase at night, it only makes sense that your security camera wor at its best in the dark.  With this basic information under your belt it’s time to researching specific products.
