How to ZAP a Camera: Using Lasers to Temporarily Neutralize Camera Sensors

tazeen — Mon, 02 Nov 2009 12:25:44 +0000

Cameras are ubiquitous today, and, from a technology perspective, the revolution is just beginning. Video cameras are becoming smaller and cheaper while the Internet is enabling unlimited live webcasting. Web camera usage has grown from one in 1991 to hundreds in the mid-1990s to hundreds of thousands today.

Camera zapping is possible because cameras are not perfect machines. Two such imperfections are blooming and lens flare. Blooming is the technical term for when a portion of the camera’s sensor is overloaded, resulting in “leakage” to neighboring regions.

Lasers are near-perfect monochromatic light sources, in that they emit a single narrow wavelength, one pure color (actually some lasers emit several pure colors). The first lasers were made of glass tubes with polished mirror ends and had the additional feature of emitting collimated light, a parallel beam so precise that it could be extremely narrow (and therefore concentrated) or could converge to a microscopic point.

Several interesting facts and researched information will be found on camera zapping.

How To Find Hidden Cameras

tazeen — Mon, 02 Nov 2009 12:21:49 +0000

While it was easy to spot cameras twenty years ago due to their large size, this has become increasingly difficult during the last decade. Cameras have become much smaller and consume a fraction of the power they did ten years ago. Due to this, stealthy installation in nearly any imaginable place is possible.

During the last few years the number of surveillance cameras has grown out of bounds. Cameras have been installed in many public and semi-public places such as universities [1], streets, supermarkets, gas stations, parking garages, cinemas, bars, shops, busses, train stations and even discos.

About 25 million CCTV1 cameras are estimated to be in operation worldwide. Some countries, notably Great Britain, are trying to fully cover every corner of public life with cameras.

Ease of use and the dropping prices highly contributed to the popularity of subminiature cameras. There is a growing number of reports of covert cameras spying on unsuspecting persons in showers, bedrooms and changing rooms.

One important reason for finding hidden cameras can be concern about privacy and personal freedom

The focus of this paper will be on electronic cameras because electronic cameras are more flexible to install and operate. They facilitate real time analysis and can be installed in places that are not easily accessible, since there is no need for changing films.

You are going to gain all the information on methods frequently used for hiding cameras as well as methods to detect and locate covertly installed cameras in this manual.

Following topics are covered in this manual:

Dummy CCTV Camera including Lens and Mounting Bracket. Uses an actual Camera body so it looks like the real thing.

Hidden Cameras operate as a back-up where primary cameras are disabled by an intruder. Used mostly for temporary installations to catch repetitive criminal activity.

Different other cameras and their specialities with methods to destroy these some other information that would help you to preparing for unpredictable events will be discussed in Guide to Closed Circuit Television (CCTV) destruction.

The contents in Guide to Closed Circuit Television (CCTV) Destruction are organized under the following headings:

WHY DESTROY CCTV CAMERAS?
TYPES OF CCTV CAMERA.
- Dummy CCTV cameras.
- Hidden CCTV cameras.
- Wall mounted CCTV cameras.
- Roof mounted CCTV cameras.
- Street post mounted CCTV cameras.
