Night Vision Camcorder – Choosing The Right Night Vision Video Camera is from Cheap Night Vision Binoculars

By Sarfaraz Nawaz

An avid hunter does not choose the right time to do the thing he loves the most. In fact, every time is a right one even if it means being in the woods at night. On the other hand, there are shooters who are just dedicated to perfecting their rifle shooting. They can extend their practice until darkness falls. Regardless, what these people-and perhaps you-need it.

What is a night vision rifle scope?

It is simply a rifle scope that comes with a night vision. This way, you can see clearly through the images even if you are using your gun in the middle of the night. It is an excellent tool to ensure that you can get what you want right on target.

How to Buy a Night Vision Rifle Scope

There are a lot of things that you should consider before you decide to make a purchase of a night vision rifle scope. Some of these are the following:

Decide on the distance you want to cover. There are far and near shooters, and what you are will tell you the kind of that equipment you should buy. For example, if you are fond of targeting objects at several feet away, you need it that is equipped with a very powerful lens, the higher the magnification the better. However, you also have to know that you may also compromise the quality of illumination that your lens is going to receive. Thus, you need to weigh which is more important to you: illumination or magnification.

Know what you are aiming for. If an object you are targeting is inanimate or not moving (think of practice shooting), you can opt for the more affordable type of night vision rifle scope. You will not have to be concerned with the object’s speed. But if you are born hunter and you have set your eyes on deer, birds, and other fast-moving animals, you have to look for it that can also catch up with their movements. Your sights can also get blurry when your target moves too fast.

Identify the time you are going to use it. This will help determine the kind of generation your night vision rifle scope will belong to. So far, there are three kinds of generations available. The higher the generation level is, the higher the ability to see clearly in the darkness. That is why if you are just going to hunt at the early part of the evening, you do not have to go for generations 2 and 3 of it. They are expensive. However, if you are fond of being surrounded by darkness or there is not enough source of light, you really have to invest in a higher-generation night vision rifle scope.

Decide on the brand. You know what they say, "You will get what you pay for." There are definitely cheap night vision rifle scopes around, but you may also have to deal with poor quality. If you are dead serious about hunting and shooting, you have to make an investment. There are good brands out there. One of the best manufacturers of that scope is ATN.

You can also shop for it can function as a regular scope. This means that you can turn off its night vision mode, so you have something to use when you are hunting during daytime and their lenses can withstand exposure to heat.

How to Pick a Night Vision Rifle Scope is from Cheap Night Vision Binoculars

Author: Hans Ortega

Photography and videography are common tools in implementing security. These measures can monitor and capture pictures of suspicious or illegal activity which could then be used to detain wise guys. They need light to work, and leaving the lights on or illuminating all areas are not options for reasons of cost-efficiency and practicality. Night vision cameras are used instead.

These devices are best known for their applications in secure environments. This is only natural, since night vision cameras work best when held still,eg when they are mounted on braces or some other mechanisms. They can capture images even when the lights are out, so places of business or banks can switch off the lights and close up shop without being worried about loss of security capabilities.

Many night vision cameras produce monochromatic photographs, that is, images with only shades of one color. This is the results of the technologies they use to capture images in darkness. Monochrome is the results of maximizing picture qualities outside of color factors.

The camera takes in the view, and particles of energy strike sensitive layers in the camera. These signals are translated into something that humans can see, so the use of monochrome where the brighter the color, the more photons or particles there were entering the camera from this point in the area of observation. Illuminating an area with high-infrared washes it in "invisible" light, which makes the scene clear and bright for the properly-equipped camera. This illumination can also be seen with night vision devices, and can serve as deterrents to any burglars who know of the security measures.

The other technology employed in night vision cameras is thermal imaging. This is good for applications where you just need to spot something by its silhouette and not by features like faces. Since they need no light and instead sense differences in temperature voiced in low-infrared, they are perfect for placement on fringes. These are generally wired to alarm systems, which would trip when any "intruder" as outlined by the programming would enter the field of view.

What is a night vision spotting scope? How different is it from a telescope?

Usually, it is likened to a telescope. This is because the device can be used to observe any object that is in the sky. In truth, though, they have a lot of differences.

For example, even if both: night vision spotting scope and night vision telescope allows you to see in the dark, you can see images a lot clearer if you’re using a latter. That’s understandable. It is a lot smaller to a telescope. Moreover, the images produced by that are always upright. It’s a norm for telescopes to let you see images in their upside down or reversed positions. Of course, because of its sheer size, a spotting scope will always be more portable than a telescope. You can also just mount the spotting scope on a regular tripod, unlike telescopes, which should have their own special mounting devices. Telescopes are also often used at night. There’s a good chance that your equipment can still function even in daylight. When it comes to magnification, you can expect telescope to have higher numbers than a spotting scope.

Who Uses a Night Vision Spotting Scope?

It is no longer limited to astronomers, both amateurs and professionals. They are also now being utilized by hunters who want to monitor the movements of their prey before they fire at a target. It is also ideal for bird watchers, especially if they have to keep their distance. You can also use it to simply capture the beauty of a certain wide location. If you’re on a boat at night grab a night vision spotting scope and you will see islands that would only be noticeable in a daytime.

You can also combine to it with a camera, particularly if you want to capture subjects that are several feet away. You can use the former to correctly identify the right angle.

The Benefits of a Night Vision Spotting Scope

As you can see, there are a number of things that you would learn to love about it. For one, it gives you the eyes when you’re in the middle of darkness. As long as you have adequate source of light for your lens, you can definitely see the subjects very clearly.

Of course, it has been mentioned that a night vision spotting scope is very portable. You can tuck it inside your bag or just hold it; it’s basically ready whenever you need it. It is also very durable. It is known to withstand fog. You also will not have any problem if you happen to dip it in water.

Options for a Night Vision Spotting Scope

You would find wide varieties today, but they can be categorized into three. You have straight-through, shoulder-mounted, and angle night vision spotting scopes.

Though they all function like regular spotting scopes, they also have their own slight differences. If you’re going to use a tripod, you may want to pick an angled spotting scope. This one would entail leaning the eyepiece around 45 degrees to spotting scope’s body. This is also perfect for individuals who are tall.

If you’re bird watching or observing views from the vehicle, choose the straight-through version. The shoulder-mounted night vision spotting scope is easier to carry since you simply have to put it on your shoulder.

Tips on Creating Awesome Night Vision Digital SLR Photos

Today's digital SLR cameras offer the photographer full control of aperture, shutter speed and ISO settings enabling the capture of excellent usable images in low light that were not otherwise possible. However, in many situations such as photographing scenes at night with very little ambient light, or telephoto photography at night at a distance, even the best digital SLR cameras simply do not have sufficient sensitivity to capture adequate images. In these situations, night vision modules such as those described here are the ideal accessory. This article provides important guidelines for producing awesome night-time photos when using a night vision module-enabled digital SLR camera.

 By adding a night vision module to a digital SLR camera, night turns into day. Follow these guidelines to assure the best possible image quality.

Because of the increased availability of high performance digital SLR cameras, capturing excellent photographs at night is now easier than ever. With full control of aperture and shutter speed settings as well as electronic gain (ISO), the photographer has the opportunity to capture images in low light that were not otherwise possible.

However, in many low-light and night-time situations, digital SLR cameras simply do not have sufficient sensitivity to capture adequate images. For one thing, with the ever-decreasing size of pixels, it's remarkable that light sensitivity has not substantially worsened with each new generation of camera (since light sensitivity is directly proportional to detector pixel area). But, fortunately, there's been a lot of camera development on noise reduction so sensitivity has kept pace if not improved slightly with the decreasing pixel area. Regardless of these changes, it remains that a sufficiently long exposure time cannot be used because either there is movement in the scene or the camera is moving (by being handheld or on a vehicle in motion) so long exposure times would result in blurring. For situations such as photographing scenes at night with very little ambient light, or telephoto photography at night at a distance, even the best digital SLR camera will be unable to produce adequate photographs without blur.

 In these situations, a night vision module such as those described here are the ideal accessory (www.nightvisioncameras.com). Such a device fits between the SLR objective lens and the camera body and amplifies the light that is captured by the objective lens, projecting an amplified (but entirely green) image onto the digital camera's image sensor. The result is up to 10 F-stops of improvement, a dramatic change enabling many applications that are otherwise impossible to photograph. The module transforms moonlit or starlit scenes into bright, high resolution images that are easily photographed.

HOW IT WORKS

AstroScope transforms dark scenes into bright, high resolution images that can be easily photographed without the need for additional lighting or longer exposure times. The objective lens focuses the minute amounts of available light onto the faceplate of its internal central intensification unit that converts the photons to electrons. The internal electron flux is then amplified and the electrons are accelerated so that when they impinge on the output phosphor, a bright green image is created. The image is then focused onto the internal detector of the digital SLR camera.

 Learn more at:  www.hownightvisionworks.com

The following are some guidelines to help assure that the Night Vision digital photos are the best possible.

Exposure Mode

Select Manual exposure mode ("M"). Not "Automatic", "Aperture Priority", "Shutter Priority", "Program" or any of the other special modes. In low light, you'll want to manually open the lens iris to permit the most light to fall on the night vision module's sensitive photocathode.

Shutter Speed Setting

You'll want to set the camera's shutter speed so that it is just long enough that there will be no blur due to motion, usually about 1/30th second. Longer exposure times will usually result in blur (for handheld applications). Shorter exposure times may provide some improvement if excessive motion is a concern but could unnecessarily darken the image due to the reduction of light being acquired from the night vision module's image intensifier. While the output brightness from an image intensifier increases with increasing scene illumination, at higher scene illuminations, the image intensifier's output brightness reaches a maximum value and remains constant as shown in the accompanying chart. (The limitation on the output brightness protects troops wearing night vision goggles from being blinded when viewing a bright light). Since this maximum brightness is not very bright (about 2 foot lumens), it is unlikely that the digital camera's sensor will be saturated as a result. So, faster shutter speeds are not necessary as a method to limit the light accumulation.

ISO Setting

While back in the days of photographic film, ISO was a characteristic that described film sensitivity to light, today, ISO is related to electronic gain of the digital camera's sensor. Since increasing the gain will amplify the low light level images, even with a night vision module, lower light scenes will become visible. However, there are disadvantages to setting the ISO too high. As with all electronic circuits at high gain, image noise can degrade image quality. As such, set the camera's ISO to a value as high as you can while still acceptable image noise levels. Usually, the minimum value would be 800, but some cameras deliver perfectly usable images at ISO 1600, 3200 or even 6400 (on some recent Nikons).

Manual Focus

When using a night vision module, select Manual Focus mode (usually a small lever switch on or near the objective lens mount). Manual focus gives you greater control over how the focus appears. Since night vision modules are generally grainy, the image grain can confuse the SLR camera's focus sensors. Also, realize that these focus sensors will be staring at the output of the night vision module so the grainy artifacts will not be affected by the focus position of the objective lens (which is located on the front of the night vision module).

Use Stabilized Lenses

A camera's image stabilization feature permits the photographer to use slower shutter speeds without resulting in blur due to camera shake. Note that there are two primary techniques for image stabilization: optical stabilization (where a small element inside the lens moves in order to stabilize the image projected on the camera's detector) and digital stabilization (which take advantage of extra rows and columns on the perimeter of the detector, shift the image an appropriate amount to stabilize certain types of motion).

Normally, the optical image stabilizers, though more expensive, are preferable since they better remove the blur component of the motion. When using a night vision module, the main disadvantage of the digital stabilization is that the image is blurred on the input of the night vision module resulting in some blur on the intensified output image. So, optical stabilization is preferred.

Lens Aperture

The basics still apply for night vision intensified low-light photography. In low-light situations, you'll want to select the fastest objective lens set to the lowest F-stop setting. (The lowest F-stop value indicates that the iris is opened up fully and will gather the most ambient light possible for that lens).

Nikon and Canon offer fast stabilized telephoto objective lenses that are ideal for night vision applications.

Infrared Illuminator

Sometimes, even with a night vision module, it's simply too dark to obtain a good quality photograph at night. A dark and cloudy night with no ambient light is one example. Since the night vision module is merely a light amplifier, if there is no light from the stars and sky or from city lights reflecting from clouds, the night vision module will not be effective. In order to photograph without the use of a flash or visible light source, a near-infrared light source can be used that emits light that can be seen by the night vision module but is invisible to the naked eye. Unlike some digital camera sensors which have some near-infrared response, night vision modules are most sensitive to the near infrared wavelength range and consequently these light sources can significantly enhance the night-time image and render night photography possible despite the lack of sufficient visible illumination.

Invisible near infrared illumination can be used to brighten scenes that are otherwise too dark.

Image Cropping

Because image intensifiers have automatic electronic gain features to maintain a constant light output, the presence of bright lights in the field-of-view (such as headlights or street lamps) may have the affect of decreasing the unit's overall light gain. This is similar to back-illuminated scenes for un-intensified photography, but even more important because of the significant impact on light gain that could result. This affect may cause the other regions in the image to darken to an unacceptable level. If possible, do your best to exclude non-important bright lights from the field of view.

Turn Off All Camera Visible/Audible Functions

For covert night vision photography, don't forget to disable all camera lighting and sound functions. (For example: disable flash, any red eye reduction mechanisms, auto focus assist, LCD preview, and all audible signals).

Use a Tripod

When handheld use is not required, select an exposure time long enough that the movement of objects under observation does not result in image blur. As with un-intensified photography, long exposures require that you hold your camera perfectly still to avoid blurring. A tripod is a perfect accessory. If one is not available, try bracing your camera against a stationary object like a tree or wall. In order to avoid the blur that results from finger pressing the camera shutter release (which can cause enough movement to blur a photo), use the camera's timer.

Portable Night Vision Scope With Infrared is from Cheap Night Vision Binoculars

By Sarfaraz Nawaz

What are the benefits of using a night vision camera? What are the choices available? Can you create your own device? These and more will be answered right now.

What You Get

There are plenty of homes and offices that are using simply because the owners understand the advantages of having one in the area:

1. You can mount it. Unlike monoculars, binoculars, and goggles that have to be worn or supported by hand while you are using them, it can be mounted or installed in a covert area. You can let it function without your own personal help. If you want to go for something hi-tech, you can opt to connect the camera to an electronic control system, which can easily change the direction of its focus. You can also connect it to your computer, so you can monitor the images it is getting without having to go outside. Moreover, if you know how to network your systems or have an Internet connection, you can actually create a live surveillance broadcast online.

2. It can be hidden. You can rarely see night vision cameras that are large in size. Most of them are very small. Nevertheless, even if they are moderately sized, you can still hide them and get the results that you want. If you can choose your own, you can end up having one that has the ability to amplify light source or magnify images. Of course, it possesses the ability to see images even if there is no available ambient light.

3. You can install it in your car. You can also make use for your car. Brand-new and highly priced luxury cars are always temptations to robbers, who'd like to sell them in the black market. You can follow the same setup for your night vision camera used in your own home. The only difference is that what you're monitoring is your own car.

You can also see it's attached to cars of police officers. Because of a its capabilities, they can see the model, maker, and even the license plate number of a vehicle.

Is it possible to come up with your own camera?

The answer is actually yes. You may simply need a camera adapter that you would attach to your household camera. You can also adjust your own webcam, so you can enhance its capability during nighttime. Most definitely, if you don't want the hassle that goes with coming up with your own, you better buy a complete product.

How technological is it?

It really depends on the manufacturer. If you know how to research properly, you can find that quickly changes to infrared mode even without your help. There are also others that can provide you with detailed recordings despite the changes of lighting conditions or the absence of a light in the area.

The best night vision camera would be equipped with thermal imaging technology. This allows the camera to capture suspects without really having to see their actual images. It depends on the heat registered by humans, animals, and even objects.

Get to Know More About a Night Vision Camera is from Cheap Night Vision Binoculars

By Simon Schwartz

So, you got yourself a pair of Eyeclops Night Vision Goggles for Christmas this year! I bet you've already tried them out and seen how they work, but, you're probably wondering what actual things you can do with them to have fun once the initial wonder at seeing in the dark wears off. Well, here are some games you can try to play out both indoors in your home, and outside in the park or in your yard.

First of all, the classic game of hide and seek is ideal for use of a good pair of night vision goggles. How you actually play the game though, depends both on whether everyone in the group has their own set of goggles or not, and if you're playing indoors or outdoors. If you're playing indoors and you only have one set of goggles between you, then what you want to do is have the lights turned on while everyone hides, since this is a lot less dangerous than a bunch of people trying to hide in the dark at the same time. Once everyone is hidden, you turn off the lights and the seeker can seek using the goggles, which is sure to provide an exciting time for everyone. Now, if everyone has their own goggles, hide and seek can be even more fun since you can actually do the hiding and everything in the dark already! Plus for a bonus, you can allow people to move around after the seeker has already started to look for you, bringing a whole new level of strategy, sneaking and stealth into the game.

Another game to try, and incidentally one that is very appropriate around October and November for Halloween, is haunted house. What you do is simply one person has the goggles and is in charge of rounding up several icky-to-the-touch ingredients like grapes, pasta, kiwis, etc. Then in a completely dark room, the person that has the goggles simply leads the others around and directs them to feel each thing, describing gruesome imaginary depictions of what it is that the other players are feeling. This is exciting for the regular players and also funny for the goggle wearer since he can actually se what everything is and also watch the expressions on their faces!

Finally, and this particular game might be reserved for adults only (and we know that more than a few adults are going to be getting their own night vision goggles anyway), we have night paintball. This game of course needs to be played outside, in a park or in a large yard. It's even better if you find a park which has a lot of trees, shrubbery and places to hide around in it. Basically, play just like you would normal paintball except that there will be about 10 minutes at the beginning for everybody to have a chance to find a good place to hide, taking full advantage of the dark. When this 'grace' period is over, the game officially begins, everybody turns on their goggles and the fun begins.

These are but a very few ideas of things you can do with your new infrared goggles. Obviously as you get used to using them and taking advantage of them you and your friends will come up with many more new things to try. The important thing is to always be safe but have fun at the same time.

Eyeclops Night Vision Goggles: Three Games to Play With Your New Goggles is from Cheap Night Vision Binoculars

Author: Joel Boness

Night vision goggles are perhaps one of the most practical inventions of the last century. They fill a need that mankind has had since it evolved sight - the need to see in the dark.

Of course, night vision goggles are far from the only means of seeing in the dark. Lights, torches and even fire serve the same function with much simpler technology... But where artificial light sources have problems is that though they let you see in the dark, its only in a limited area. Night vision goggles have no such limitation.

Instead of creating light, night vision goggles allow you to see in an expanded spectrum of light. All light is part of an electromagnetic spectrum and normally human vision is confined to a small section known as 'visible light'. Night vision goggles come in a variety of forms, from simpler devices which simply allow the eye to gather more visible light, to devices which make use of the infra-red or electromagnetic spectrum for night vision.

They also have another significant benefit - the ability to see in the dark without making yourself the most visible thing in the night. You may be asking why this benefit of night vision goggles really matters, but it is one of the major reasons night vision goggles are becoming increasingly popular for private, government and commercial use.

Uses of night vision goggles:

1. Military operations; unsurprisingly, armies around the world have made effective use of night vision goggles in night-time operations. The military has driven development of night vision technology over the last century, creating the first generation of true night vision goggles during the Vietnam war. However, snipers in the US army and German tank drivers were using the simpler 'night glass' technology as far back as WW2.

2. Security; a less dramatic, but equally logical use of night vision goggles is in the security business. Many CCTV cameras incorporate some form of night vision, but for larger areas, security officers often make use of night vision goggles. This allows them to approach trespassers and criminals without alerting the miscreants to their approach. Many private users of night vision goggles also use them for this purpose.

3. Navigation; night vision goggles allow you to see much more clearly than a torch. Rather than a narrow beam of light, your entire environment can generally be seen clear as day. This is particularly useful in forest environments, where following overgrown paths can often be confusing via the narrow focus of torchlight. Aside from simply walking, night vision goggles allow people to drive off-road in hazardous terrain where headlights would provide an incomplete picture of the environment and are particularly useful for pilots. Pilots of helicopters and small aeroplanes make use of night vision goggles to make landing approaches in badly lit environments, or to see some of the terrain below them for better navigation.

4. Wildlife activities; a slightly more pleasant use of night vision goggles can be found in the wild. Nature enthusiasts are some of the main commercial users of the technology, using the goggles to navigate the wilderness in the dark and to see nocturnal wildlife. Without night vision goggles, this would usually be impossible - walking around with a torch is usually more than enough to scare off deer, rabbits, badgers and other animals.

5. Law enforcement; aside from the ability to chase down criminals in the dark, some forms of night vision goggles have an added benefit. Thermal imaging devices can often reveal an amazing insight into recent activity in an area, whether simply heat residue from footprints or even whether suspects have buried objects or even hidden them in walls. Even if an area seems pristine to the naked eye, thermal goggles can reveal clear signs of such activity.
