Surveillance Equipment

Night vision devices can be used for a multitude of reasons.  For instance, some people will use cameras and binoculars for watching property as a means of protection, some will use the devices for camping or hunting, and others like the option of seeing in the dark simply for fun.  As you will discover, there are many options for night vision, no matter the purpose needed.

One of the most popular and affordable night vision devices is with binoculars.  These special binoculars are designed so you can see things in the dark quite clearly.  Of course, there are different levels of quality but most work exceptionally well.  As mentioned, there are all kinds of reasons a person would consider using night vision binoculars to include:

• Security/surveillance
• Wildlife observation
• Cave exploration
• Scouting or survival games
• Camping trips
• Fishing and boating
• Hunting
• Navigation

The majority of night vision binoculars on the market today have the same concept as digital cameras, meaning there is a built in flash that makes it possible to see at night.  In addition to quality, there are also various sizes and price ranges.  If you want a powerful set of night vision binoculars, you would expect to pay but depending on the purpose, it might be an investment worth making.

The first thing you want to do when buying night vision binoculars is to first determine the way in which the device would be used.  Obviously, if the binoculars are being purchased simply to watch nighttime wildlife or for kids to have fun on a camping trip, then you would not need something top of the line.

The way night vision binoculars and other devices for seeing in the dark work is by taking any light in the dark and amplifying it.  What makes this so fascinating is that even light the eyes are not able to see is used.  This coupled with infrared spectrum produced with an infrared illuminator is able to take the darkness and create light that the eyes can see.

When looking through any kind of night vision device, you will immediately notice that everything is green.  If you were to take the binoculars or other device away from the eyes, you would see only darkness.  However, when looking through the lens or on a phosphor screen, the nighttime would become illuminated in green, allowing you to distinguish items quite clearly.

Keep in mind that night vision binoculars, cameras, and other devices will all work somewhat differently based on the light conditions.  If you want to see in low light situations, then you would need a powerful device.  However, for viewing in medium light where there is a bright moon or lots of stars, you would need something else.  Of course, there are night vision devices that have various features that would allow you to make adjustments according to the light conditions.  The following is a great guideline for buying generation binoculars (Gen).
Gen 1 – Used in conditions where there is a bright moon and stars
Gen 2 – Night vision that works best in conditions with a crescent moon
Gen 3 – Best for dark nights with or without cloudy skies
Another consideration for night vision devices has to do with the range.  The distance in which you would be able to see at night depends on certain dynamics to include resolution, gain, and magnification.  A good choice overall would be binoculars that have a 5x magnification or less but of course, you would want to look around to make the right choice.

Another option for night vision is with monocular devices.  In this case, you get the same advantages of having binoculars for seeing things in the dark but with one exception.  Monocular devices are far more affordable than that of binoculars.  The bottom line is that there are great options on the market, as well as cameras.  Therefore, start with the purpose for needing a night vision device, then choosing the equipment that would give you the results you want.
