At first glance, a night vision video camera might seem like an unnecessary extravagance. However, video cameras with night vision have found their niche in several industries, including hunting and personal security. These devices are surprisingly affordable and can be purchased at many places online and off. Where can you use one of these cameras that see at night? Read on and be amazed...
For the purpose of hunting and wildlife conservation, night vision video cameras assist with the counting of herds and species identification. Hunters can purchase cameras with night vision to scout out prospective areas prior to the expedition. Some models even have an option to link to the camera live online and see the real time video as it is shot. Conservation officials can locate and identify where animals are coming from and going to.
Security applications are another popular place where night vision is a requirement in video cameras. Whether in a multiple monitor system or a single one, night vision lets the watcher see the darkest portions of the property and alert law enforcement accordingly. Since the video is recorded, if the perpetrator does get away, there is a nice video of them.
Night vision video cameras come in two different varieties, depending on what you want to spend and what you expect to get from your camera. The first type is simple night vision where the camera collects the available light and uses it to bring the objects in the viewer into sight; even though you cannot see them with the naked eye. This is the most popular type and it does require a small amount of available light to work properly.
The other type is thermal imaging and requires no light whatsoever. Instead, these night vision video cameras interpret the infrared frequencies as heat signatures. They then relay the signal to the screen in varying colors according to the temperature that is received. As we said, this type of night vision requires no light at all to work and can be used in complete and utter darkness with great results.
Both types of night vision video cameras use infrared technology. The difference is the way that each one uses and interprets the light it gathers. Standard night vision takes the available light and bends it around the objects in the viewfinder, making them visible to the user. Thermal imaging reads the higher end of the infrared frequency range and shows it on-screen as a colored image in the shape of the objects being viewed.
In any case, using a night vision video camera can show you what you would normally not be able to see. This makes for a safer, more enjoyable venture into dark places like the woods, a warehouse or a building with no power. This technology is no longer only for the military or law enforcement officials. Anybody can own and operate a night vision video camera and they are readily available in many models and with many attractive features.
All you need to figure out is what you want to get out of your night vision video camera and get the appropriate one for your needs.
