Hidden Cameras are covert camera devices that are used to keep surveillance over a particular area. They are usually installed at hidden places or cleverly disguised in other unsuspicious articles. The camera continuously records images in its field of vision, which can be retrieved and seen on a computer or TV monitor. Both simultaneous as well as recorded telecasts are possible.
The major use of Hidden Cameras is security. Almost all department stores, banks, hospitals, airports, casinos, etc. have Hidden Camera security systems. These cameras are connected to a monitor in the security cabin, which is continuously manned. Several cameras can be hooked onto the same monitor forming a CCTV network. CCTV Hidden Cameras are very popular security devices.
For home use, smaller Hidden Cameras are available, which are also called as spy camera or nanny cams. They are installed at secret places inside the homes so that people can keep a watch over their children’s nannies or caretakers of senior citizens while they are not at home.
Earlier Hidden Cameras used to be big devices which were not easy to conceal. But present-day cameras are so small that they can even be disguised as a shirt button. The most important component of the camera is its lens, which must be kept clear so as not to obtain muddled images. Lenses are available in miniature sizes so that the size of the camera itself can be very small. The beauty of a Hidden Camera is that it can have a clear field of vision without itself being seen.
Hidden Cameras also have many other uses. Such cameras are installed on traffic signals in order to control traffic. People running down signals can be nabbed by viewing them on the screen. Even impending accidents can be avoided.
However, the use of Hidden Cameras is also a controversial issue. Many people think a Hidden Camera is an invasion of privacy. Though Hidden Cameras have managed to book several shoplifters, the very aspect that Hidden Cameras treat everyone as guilty is gaining controversy. Another major controversy is the use of Hidden Cameras in private places such as hotel bedrooms and restrooms, and using the images for pornographic purposes over the internet. The use of Hidden Cameras is bound by several legislations, which differ from state to state. Despite that, Hidden Cameras are being progressively used all over the world for security and crime prevention.
