What exactly is the purpose of a security camera, what were they invented for? Well as far as I am concerned as well as any one who owns one or even back to the person/s who invented it was to inhibit criminal activities, to capture the criminal right in the middle of the act on camera. But here is the problem that we face, crime does not only happen in the day but also happens at night but not all cameras work well at night without the aid of an additional external light to aid it. For one thing, it is an extra overhead expense on a companies part and particularly for nature conservationist who use cameras to monitor animals in their natural habitat at night this would hinder there progress. For that specific reason one such camera exist that takes care of this problem, night vision security cameras.

The thing is most security cameras have the ability to produce relatively decent pictures in dim or low light but is an impossibility for them in total darkness, which is the weakness in most cameras. As previously stated this is where night vision security cameras come in, but with one slight disadvantage in that the current generation cannot record in color but in black and white. There is however an option of getting those equipped with a hybrid configuration that allows it the ability to produce color images in good lightning but returns to black and white in night vision mode. This however is an aside considering it does its job and keeps view of the surroundings even in the dark.

There are many shows and movies on television depicting night vision goggles and cameras whereby the image produce is something like a green background or coloring with shadows for images. What you should know though in reality images produced from the night vision security camera are somewhat similar but however the actual quality and detail or the produce images are much more defined and therefore are liked more by people in comparison to what is seen on television.

Is a night vision camera and an infrared camera the same?

Are they? No, they are not he same. Most confuse the two and think that night vision cameras use infrared to film images. However, they could not be further from the truth. Infrared security cameras utilize the heat emitted from an object to aid it in capturing images and make them visible. This in movies is usually depicted as a yellow and red image against a black background projecting the difference in the heat produced between the object in view and the surrounding area. A night vision camera on the other hand however is equipped instead with small light that is emitted to focus on a specific object in order to record the image.

Now if you intend to utilize a night vision camera to view what goes on around an object this should be a job done by an experienced professional or on the advice of one familiar with these cameras. This is so because of external light appearing from the surrounding areas can confuse the camera into thinking there is more light present than really is there. This more or less then obstructs and interrupts the internal mechanism that automatically switches camera modes and renders a disorganized video. Just to say, it fools the camera and makes it use less light than normally needed making it unable to get a proper picture.

All said and done, the price tag on one of these cameras while not exactly ridiculous, still when you look at it is more reserved to locations or to persons who have that extra amount of funds to spend on their personal security.

Night Vision Cameras. Protection in the Darkest Night is from Cheap Night Vision Binoculars

The Many Uses of Thermal Night Vision Technology is from Cheap Night Vision Binoculars

Author: Michael Page

When night vision goggles and scopes were invented they were strictly used in military applications. German engineers had primitive models functioning by the end of WWII, and many German tanks employed them in battle against Allied forces. Early U.S. design technology of the NVD's (night vision devices) was classified, but inventors in the private sector soon caught up and commercial applications came to the market. Law enforcement agencies used night vision goggles and scopes for monitoring purposes, and private investigators soon picked up on the innovative equipment.

Today's night vision goggles and night vision scopes are considered to be Generation 3 and Generation 4 models using highly advanced technologies. Military and law enforcement continue to be major users of this equipment, but like with other technologies developed by the military, night vision goggles and night vision scopes are making their way into mainstream use with increasing regularity. Who's using them?

Private investigators rely on night vision goggles for their surveillance needs. Much of the activity they track happens after dark, and night vision goggles give them the opportunity to follow subjects at night and from a distance. Night vision goggles are expensive, but that cost is often passed along to their clients who are eager to obtain certain kinds of information.

Nature lovers are also using night vision goggles and scopes to view wildlife after dark. Many nocturnal creatures can be sighted and watched with their use, including owls for birding enthusiasts, and mammals such as bobcats, bears, flying squirrels, fox, and coyotes. Many nature watchers don't realize how much there is to see after dark in their back yard or nearby park until they have the needed equipment to do the viewing. Night vision goggles open up that world to serious nature observers who have the money to purchase the equipment.

Hunters are also making use of night vision scopes and goggles. Bushnell and Zeiss are two leaders in optics and they have entered the market with night vision scopes that offer excellent technology for viewing wildlife after dark. While most states ban actually shooting an animal after dark, the night vision scopes give hunters the chance to observe their quarry to track location and movement.

If you plan to purchase night vision goggles or night vision scopes, be sure to check local laws concerning their use, particularly for hunting purposes. Using the equipment for observation and surveillance should not be a problem as long as the use is consistent with laws governing surveillance in general.

Never Be Left in the Dark with Night Vision Goggles and Scopes 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: Ricky Lim

There are various different kinds of night vision goggles a person can use which have been specifically designed for use on land. In fact a number of the more well known night vision goggle manufacturers have produced ones for thermal use. Below I will take a closer look at some of the thermal night vision goggles that are now available to purchase.

TAG-7

TAG-7 offer the wearer one of the best performing thermal systems available today and are not that expensive to purchase. All a person needs is 2 AA batteries and comes with a head strap so that the wearer can use their hands on other tasks whilst using them. Although they only use AA batteries, these thermal night vision goggles still provide the wearer with a good clear image of their surroundings which have not been exposed to either light or shade. The great thing about these goggles is that they are small and lightweight and this makes them very comfortable for the user to wear.

ATN Otis-G7

These are another version of thermal NVG’s. The great thing about this particular pair is that they can either be attached to a helmet or the person can carry them in their hand. With this particular version you are actually offered the chance to connect to a video.

Because of their design the image you see through the goggles will be clear or unaffected by anything else around it. These particular goggles work by constantly detecting changes in heat from a body as well as the temperatures around the wearer. The thermal imaging used within these goggles ensure that the images are of the highest quality possible. Today these particular thermal night vision goggles are being used by members of law enforcement units along with units that deal with public safety such as firefighters.

The technology that is used in thermal night vision goggles works by capturing the upper part of the infra red light spectrum. This light is emitted through the heat of an object and rather than relying on the reflected light as other kinds of night vision goggles do. The hotter the object then the more of this light the object will emit. So when you use these you will see that a human body will emit more infra red light than say a tree or a building will.

What are the Best Thermal Night Vision Goggles? is from Cheap Night Vision Binoculars

Author: Ricky Lim

There are a lot of different night vision goggles for anyone to choose from, that have been made for land use. Plenty of manufacturers that make night vision goggles produce only thermal versions. In this article I will talk a bit about some thermal night vision goggles that can be purchased.

TAG-7

TAG-7 is one of the best thermal night vision goggles available to buy, and the price isn’t really that high. 2 AA batteries is all that is needed for it to work, and the head strap that is used to attach it makes sure that the hands are free at all times.

Even though the power source consists of AA batteries, the TAG-7 give you a very good image in night conditions without shade or light. The small weight and size are other good attributes of this gadget, making them easy to wear in any conditions.

ATN Otis-G7

Another thermal night vision goggle is the ATN Otis-G7, which is designed so it can be put on a helmet or carried in hand. You can even connect it to video if you want to.

They are designed in such a way that they offer the owner a great image that is clear of any interference. They will detect any changes in heat constantly, taking into consideration the wearer’s body heat.

These goggles are designed so they offer the best image quality, and they are even used by law enforcement agencies, fire fighters and other official agencies.

Thermal night vision goggles capture from the infra red light spectrum the upper part. Objects emit it through their heat, so they don’t need to rely on what light objects reflect. Objects give more light the hotter they are. A wall or a tree will emit much less infra red light than a human body would.

Cheap Night Vision Goggles is from Cheap Night Vision Binoculars

EyeClops Night Vision Goggles represent another step-forward in child's toys. Using technologies once reserved for clandestine operations, this "toy" allows children to see at night.

Frankly, it's amazing.

Since I am in the retail business, I bought a few for my kids to test out. I thought the EyeClops Night Vision Goggles may be one of the typical "disposable" gifts that kids receive each year--a gift that they use once and quickly abandon in favor of the latest toy.

Often times, manufacturers exaggerate the capabilities of their products. Before my kids used the EyeClops Night Vision Goggles, I had read that these goggles allow you to see up to 50 feet in complete, absolute darkness.

My son and I devised a plan to test this claim. During the day, we mapped out an area in the backyard 50 feet from the house. I wrote down a question on a piece of paper that he was not allowed to open until the time was right.

Later that night in complete darkness, I told my son to walk to the area 50 feet from the house, open the question that I had given him, and yell out the answer to me. Eyeclops Goggles in hand, my son went to the designated area.

He opened the secret question and yelled "THREE".

From 50 feet, he could tell how many fingers that I was holding up. I was in shock at the ability of these Goggles and the fact that this technology comes at this EyeClops Night Vision Goggles Price.

Beyond this "cool" factor, I was not sure that my kids would like these goggles as a toy. But they don't just like them, they love them. They use them both indoors and outdoors playing all types of creative games.

I now see clearly...EyeClops Night Vision Goggles make a great gift for kids at Christmas or anytime of the year.

The Best Review: Eyeclops Night Vision Goggles is from Cheap Night Vision Binoculars

By Robert Thatcher

At the mention of night vision devices, images can come to mind like spy and action movies, soldiers scouring an area with the device at night, helicopters hovering overhead aiding the police in tracking fugitives or detectives using the device to spy on people they were assigned to track.

Night vision devices are actually light enhancing and thermal imaging tools. It makes a particular subject visible by the warmth it emits or observable by using limited light. It enhances a spectral range making the viewer see lights and images that would otherwise have been invisible to the bare human eye. The normal human eye is capable to seeing images that are confined to a certain electromagnetic spectrum that the brain interprets. Night vision devices may use another source of light that enhances images enabling the user to detect objects that improves the detection capacity of the normal eye.

In theory the human eye can see these weaker sources of lights but the brain has a way of filtering out these lights that we are only capable of seeing a very limited number of photons. With the aid of a night vision device, these photons intensified by the photo multiplier tube enables us to see different colors of lights in a subject. When seen though and NVD, an image that is nearly invisible becomes observable.

Many animals have this capacity to see through the dark. Animals that can hunt at night uses a larger optical aperture, an improved composition in the retina, optics that are more photo-efficient that enables them to use weak lights and see better in the dark.

Night vision devices that most people are familiar with are the night vision goggles. This night vision device has an image intensifier that converts weak lights from the near infrared spectrum to visible images that enables the eye to see objects as far as 200 feet in near complete darkness. This night vision device displays a green image because the peak sensitivity of the human vision is near the green range. It also uses two different technologies depending on your choice of the night vision device.

One uses the Image enhancement where the night vision device enables the viewer to see images by collecting tiny amounts of light that may already be imperceptible and amplifying it to make the image visible. The other is through thermal imaging where the heat emitted by the subject is used and translated into images. The principle is that hotter objects tend to transmit more light than the cooler ones like stones and trees.

Night vision devices were originally intended for military use to aid them in tracking down an opponent at night. It has evolved now into many different uses.

Lately night vision devices are finding use outside of the military and police detection work. When you are out camping, night vision devices could prove very helpful. Businesses have also been installing night vision devices within and without their properties to enable them to observe if something has been touched or changed during the night. Night vision devices are also proving to have invaluable aid in detecting soil that have been disturbed, buried objects, footprints and almost anything that needs to be determined in instances where there is very limited lighting.

Some of the more common applications for the night vision devices are entertainment, hidden-object detection, hunting, law enforcement, military, navigation, security, surveillance and wildlife observation
