We can start by asking the question: what exactly is a hidden camera? Wikipedia defines it as a ‘still or video camera used to film people without their knowledge.’ Such cameras are hidden, either by being placed in a position where they are not visible, or by being disguised as other objects. With the advent of modern-day technology, hidden cameras may be disguised as most everyday objects, including but not limited to radios, mobile phones, ball caps, smoke and motion detectors, and even potted plants!
Cameras that were small enough to fit in watches existed as early as the 1880s, but since then, advances in electronics and miniaturization and electronics have greatly reduced the size of cameras while increasing their quality and affordability. This has led to the development of a whole new group of cameras called spy cameras or sub-miniature cameras. In fact, some consumer digital cameras are so small, that they can also be classified as spy cameras. We get more info on hidden camera.
A drawback to miniaturization, however, does exist. The smaller the camera taking the picture, the blurrier and more out of focus the image will be. However, technology has stepped in and created programs to clean up this images.
Hidden cameras can be obtained without much hassle. They can be ordered off the Internet, or else they can be obtained at many convenience stores in most parts of the world. A quick Google search for hidden camera sales gives us nearly six million hits. Many websites that sell such cameras claim to have hidden cameras that can be disguised as virtually anything, including stationery and clothes.
Hidden cameras can be of two types, wired and wireless. Wired hidden cameras are usually connected to a television, VCR, or a Digital Video Recorder. Conversely, wireless hidden cameras do not need to be physically connected to anything, but transmit a video signal to a receiver within a certain specified radius (usually below a hundred feet).
Hidden cameras can be used in various ways, some of this being nefarious. Spy cameras are usually important in espionage, and can be used to capture sensitive information. This does not only apply to government and military information, but also to industrial information. Since industries get a great advantage over competitors if they know information about them, some unscrupulous industries may engage in industrial espionage.
Hidden cameras are also used for security purposes in homes and institutions. Although most structures already have other security measures, the hidden cameras are usually used as a backup system to ensure that even if the other security measures are penetrated, the perpetrator shall be known.
Such cameras are also an important tool of paparazzi. Such people take images or videos of celebrities, usually going about their day to day routine, and sell them to gain money. Such images or videos are most often taken by hidden cameras, in order to not attract the attention of the celebrities.
