Here are some more information for Camera Made:

The pinhole camera is one of the earliest cameras used in photography. It is an-odd looking thing because, unlike other cameras, it does not need to use lenses to take pictures. To explain, images are projected into the pinhole camera when light passes through a tiny hole in its box-like frame. According to Wikipedia.com, the small hole of the camera can focus light by directing it through a single point. This article will talk about its illustrious history.

Early Discoveries of The Ancient Greeks

Pinhole camera history in Wikipedia.com says that these simple devices were already used by the Greeks as early as 500 B.C. It was a common belief that people were able to see because the light rays were bouncing from the human eye. Wikipedia.com adds that, later on, they found out that seeing was actually an effect of light rays entering into the eye, rather than bouncing from it. This important realization led to a better understanding of how these work.

Ancient china

Mo Jing, a Mohist philosopher in 5th century-China, was said to have studied and experimented with phenomenona of images projected via a very small hole. Because of this, the Mohist philosopher was able to contribute to the development of the pinhole camera and the Burning Mirrors used by the ancient Mohists. Much of the pinhole camera history revolves around key events in Ancient China. In fact, Wikipedia.com also states that Shen Huo, a Chinese scientist during the Song Dynasty, was able to establish the key geometrical and quantitative concepts vital to the development of the pinhole camera today.

1000 to 1600 A.D.

The 10th century Muslim mathematician Ibn al-haytam is credited for inventing the first modern pinhole camera. Further advancements were made to the camera when the Muslim mathematician realized that a smaller hole produced a more sharper image.

In addition, more ideas and studies were done by the brilliant minds of Gemma Frisuis and Giambattista della Porta. These two published a paper explaining why images projected into the pinhole camera appeared upside down. Lynn Bryant, writing for a video surveillance website, said that the studies made by Gemma Frisuis' of a solar eclipse projected into a dark room was the first documented use of a pinhole camera in history.

1800s and Beyond

Lynn Bryant also says that Sir David Brewster, a Scottish scientist, was the first one to take pictures with the pinhole camera back in the 1850s. Lynn Bryant also says that this simple camera was not regarded as a popular medium of photography, not until the 1960s. It may be owing to the fact that the photographers during the period preferred to take pictures using a conventional camera, as opposed to the pinhole camera.

The pinhole camera history can be traced back to the Ancient Greeks, with advancements contributed by the Ancient Chinese and by brilliant scientists and philosophers in the late 20th century. Its history, like the histories of all things ingenious, is colorful, interesting, and absolutely eventful, and one that never fails to prove how great things can come from a simple idea.

Choosing the Right Hidden Camera or Spy Camera

Not sure what kind of hidden camera that you need? Hopefully this article will help.

Monitoring a room using video capturing equipment is fairly easy. There is a wide variety of equipment on the market to accomplish this. Listed below are some of the different types of equipment used to covertly capture video.

Miniature Wireless cameras

Hidden wireless cameras

Hidden IP cameras

Miniature Hard wired cameras

Hidden hard wired cameras

Motion activated all-in-one recording systems

Motion activated still shot cameras

Miniature Wireless cameras

Miniature Wireless cameras can be a suitable choice given the right situation. A mini wireless camera will need power to operate the camera, whether it is battery or plugged directly into the wall. Most mini wireless cameras will run on a standard 9 volt battery. The battery will last between 4 and 8 hours depending both on the battery that you choose and the camera specifications. I generally recommend plugging it into the wall when possible.

Some other considerations are where to conceal the camera and where/ what to record on or view the camera on. The camera could be easily hidden in a plant or you could build something to conceal the camera. Most mini wireless cameras have a pin hole lens so you can easily hide them in a box or possibly in a book or anything else that you can think of. You could even set the camera inside of an air vent looking out. Recording is probably the biggest obstacle. The receiver can be plugged into a TV for viewing live. However, If you cannot sit and watch all the time there is a good chance that you will miss all the action. You could also plug the receiver into a VCR to record onto a VHS tape. The problem there is that you have to find a place to hide the VCR and you can only record as long as the VHS tape will allow. For example, you start recording at eight o'clock in the morning when you leave for work. Your partner is due home at Two o'clock. If your tape will only hold six hours you are going to miss what you were trying get catch on tape. You could also you a digital video recorder with motion activation. This is probably a better choice, but still has problems. A Motion activated recorder works great with a hard wired camera, but has problems when it comes to wireless cameras. The way a motion activated DVR works is that it can sense the pixelation change coming through the camera when something moves and knows to record. All wireless cameras have interference. There is nothing you can do about it. It's just the nature of the beast. When the DVR senses the change in pixels caused by interference it thinks it is motion and ends up recording almost all of the time.

There are better options that I will cover in the paragraphs to follow.

Hidden wireless cameras

Hidden wireless cameras, also know as a nanny cam, makes things a little easier because the camera comes pre hidden. You can get wireless cameras built into just about any thing you can imagine from televisions to air fresheners. While these cameras do make it easier you will still have the same concerns with recording as you would with a standard wireless camera.

Hard wired miniature cameras

Hard wired miniature cameras are definitely more reliable than wireless but still pose some problems. As with the wireless camera you still have to hide the camera and find a way to record or view the camera. The main problem with the hard wired camera is that you have to run a cable from the camera to the recording device. In some situations this may not be a problem, but in most situations it is not practical.

Recording is easier with a hard wired camera because you can use a motion activated DVR effectively. For instance in the example given for wireless cameras you could start recording when you leave for work and the motion activated DVR would not record anything until it saw movement in the cameras range. Most motion activated DVRs can be adjusted to record for a very long time. Pre hidden hard wired cameras can also be purchased.

Hidden IP cameras

Hidden IP cameras are similar to a hidden wireless camera in that they come pre concealed inside of many everyday items and they are also wireless. That is where the similarity ends. With an IP camera the video signal is sent through the electrical system of the house. The receiver is then plugged into a wall outlet near your computer and connected to a USB port on your computer. Using the software that comes with the system you can then view and record the images on your computer. An IP camera will also enable you to view your camera from anywhere in the world with internet access as long as the computer with camera connected to it is also connected to the computer.

The one drawback to an IP camera is that the software is not hidden on the computer. So, if your partner sees the software on the computer you may have some explaining to do.

Hidden still shot cameras

Hidden still shot cameras may be a good option depending on the circumstances. One of the best brands that I have found is the Home Guard. It is motion activated and records pictures at an adjustable frame rate when it senses motion. You can adjust the frame rate from one picture every second when motion is detected to ten pictures every second. I normally suggest setting it to take one picture every second.

There are no wires or cables, it records onto an internal chip and saves the images for future viewing. The Home Guard looks like an air freshener so it will "fit in" in any environment. Most of my clients that use the home Guard will take a sticker off of another air freshener product such as Glade or Air Fresh and place it on the home guard to make it more believable.

Motion activated all-in-one hidden camera

Motion activated all-in-one hidden camera/recording systems are my hidden camera of choice. They come in a very large selection of products making it easy to select one that will work in almost any situation.

These devices are totally self contained. They can be easily deployed and take away all of the worries that you may have with other choices that you may be considering to capture video.

The all-in-one units are motion activated and require no cables, receivers or external recording devices. Simply place the device where you want it and let it go to work. You can then view the video that it recorded right off of the unit itself or remove the SD card and view the video on a computer.

This is by far the easiest and most reliable of the options available to secretly capture video.
