During the last few years, the number of surveillance wireless cameras has grown out of bounds. Wireless Cameras have been installed in many public and semi-public places such as universities, streets, supermarkets, gas stations, parking garages, cinemas, bars, shops, buses, train stations and even discos. Wireless Camera RF Detector Miami Beach Coral Gables.

About 25 million CCTV wireless cameras are estimated to be in operation worldwide at the time of writing. Some countries, notably Great Britain, are trying to fully cover every corner of public life with wireless cameras. The Privacy International CCTV states that between 225 and 450 Million Dollars are spent on surveillance technology in Britain per year, involving an estimated 300.000 wireless cameras. These efforts result in a person driving through the city of London being filmed at least once every five minutes. In the near future, wireless cameras may even be installed in all taxis, keeping an eye on the passengers. In Houston, Texas, about 400 cabs have been equipped with such cameras.

It may not be obvious right away why it could be of any importance to anyone to be able to locate wireless hidden cameras.

Some will reason that concealed wireless cameras are more or less exotic and thus knowledge on how to find them using rf detectors is not necessary at all. Others even consider interest in how to locate wireless hidden cameras to border the criminal. Wireless Camera RF Detector Miami Beach Coral Gables.

Contrary to common belief, wireless hidden cameras are nowhere close to exotic. In 1996 David Fletcher, chief executive of the British Security Industry Association estimated that employers were spending 12 million British pounds a year on covert wireless camera equipment to monitor their staff. A survey conducted by the American Management Association found that “33 percent of major U.S. firms say they tape employees overtly or covertly to counter theft, violence, or sabotage”. There have been several reports of staff being monitored in changing rooms without their consent.

Subminiature wireless cameras were even discovered during treatment at an oral surgeon’s practice: the wireless camera was plastered into the ceiling next to a ceiling light it was discovered using an RF detector. Subminiature wireless camera modules are available for as cheap as $25 and even ready to use wireless subminiature cameras can be legally bought.

Ease of use and the dropping prices highly contributed to the popularity of subminiature wireless cameras. In effect highly, miniaturized wireless cameras can be bought, installed and operated even by the average citizen lacking financial resources and technical expertise.

Due to this, it is not uncommon for subminiature wireless cameras to turn up in places that are in fact neither public nor semi-public.

There is a growing number of reports of covert wireless cameras spying on unsuspecting persons in showers, bedrooms and changing rooms after an area sweep using rf detectors. Knowing how to find covert wireless cameras makes the voyeur’s job harder. Often even legally installed and operated CCTV wireless cameras are abused to peep on women for voyeuristic purposes. An analysis showed that 15 percent of all targeted CCTV surveillances on women initiated by the wireless camera operator were for “apparently voyeuristic reasons”.

While there is concern that persons interested in finding hidden wireless cameras may have criminal intentions, there are legitimate reasons for such interest as well. One important reason can be concern about privacy and personal freedom. Especially the growing use of face recognition software is being strongly criticized. There is no way to distinguish wireless cameras that are connected to face recognition systems from those that are not.

This is why persons who consider face recognition to touch their personal freedom may choose to avoid surveillance wireless cameras altogether. For instance, they may decide to avoid stores that excessively use wireless video cameras and visit stores that do use significantly less or even none at all. This is not possible unless the presence of wireless cameras is detected in the first place using, for example, an RF detector. In countries with lenient privacy protection laws, video sequences captured by CCTV wireless cameras may even be legally shown on TV, no matter how humiliating this may be for the affected persons.

RF transmission Cameras

The classic method to wirelessly transmit signals is to use modulated radio frequency (RF). RF video transmitters can be detected with special detectors such as spectrum analyzers detector. Spectrum analyzers detectors graphically display a frequency versus signal strength. It is possible to tell from the displayed graph what frequencies a signal is composed of. Video signals have several well-known typical characteristics. The standard NTSC color video signal has a bandwidth of 6MHz (though less than 600 kHz are possible), a line RF of about 16 kHz and a vertical sync frequency of 60 Hz. Video modulated RF signals thus can be distinguished from other signals. Wireless Camera RF Detector Miami Beach Coral Gables.

Analysis with a rf detector can be tricky if the signal is transferred digitally or if frequency hopping, burst transmission or an exotic modulation is used. Examples include the so-called spread spectrum detector which masks transmissions as random noise. In this case more sophisticated detectors such as Vector Signal Analyzers are needed.

In a “video countermeasures detector” is proposed that consists of a flashing light bulb. The basic idea is to coerce the camera into generating a video signal of known characteristics. The RF signal emitted by the video transmitter can be identified by scanning the RF bands for signals that match those characteristics. Wireless Camera RF Detector Miami Beach Coral Gables.

Standard video links that are available from most HiFi equipment dealers can be identified with a rf detector very easily.

Most transmitters operate in the 2.4 GHz band and use one of five freely usable channels.

As already mentioned scanners detectors are available that scan those channels for video signals.

Because this type of scanner only scans a fixed set of frequencies it cannot be used to reliably detect RF video transmissions.

Detecting the camera’s emissions Most wireless cameras emit a typical spectrum of electromagnetic (RF) noise.

The emissions mostly result from the pixel readout clock signal and components of the video signal.

The emitted spectrum is quite similar to any camera that generates a standard video signal.

It is possible to locate electronic wireless cameras by scanning with a detector for this spectrum.

Depending on the frequencies of the signal components proper shielding may foil detection attempts.

But often wireless cameras are not shielded at all.

Most wireless cameras transmit information, whether data, video, or voice, through the air by using radio waves. The standard counter-measure for bugs of this nature is to search for such an attack with a radio frequency (RF) receiver or detector. Lab and even field-quality receivers are very expensive and a good, working knowledge of RF theory is needed to operate the equipment effectively. Counter-measures like burst transmission detector and spread spectrum detector make detection more difficult for detectors. Wireless Camera RF Detector Miami Beach Coral Gables.

There are two main types of spying technology that most people who are being spied on come in contact with, video and audio. In either case, the devices that are being used operate on a radio frequency (RF) system.

The technology to operate and construct these devices is fairly simple and has resulted in “bugs” .

That are no bigger than a penny.

They use a lower range of RF, between 1-3 MHz which is generally on par with that of a garage door opener.

Unfortunately, because their size is so small, they can be placed almost anywhere to capture their intended information. In some instances, like a phone conversation, they do not even need to be placed on or in the phone. They only need to be placed near the phone. Wireless Camera RF Detector Miami Beach Coral Gables.

Some common different types of operational bugs that are used in RF

– Simple audio modulation and transmission: easily picked up by a simple receiver or scanner

– Digitally encoded transmission: received by a special receiver with the decoder.

– Spread Spectrum transmission: otherwise known as frequency hopping, as this type of modulation changes the actual center frequency of transmission many times a second in which a specialized receiver is used to intercept. This makes the overall finding of the bug’s transmitting frequency difficult.

– Single or Double modulated side band: (SSB, DSB) – where the modulation of the signal is found only in the sidebands of the transmission. Can only be received with a special receiver or equipment tuned to the modulation of the carrier.

– FM, NFM, WFM, or AM: common types of modulation such as Frequency Modulation, Narrow-Band Modulation, Wide-Band Modulation or Amplitude Modulation.

The basic “video bug” or video transmitter consists of a lens or aperture in which optical information is transferred to a series of photocells, usually in a grid pattern. The CCD or Charge Coupled Device receives light strength and/or colors which are commonly interpreted by a microchip.

The signal is then encoded, which in turn is processed into a standard video pattern.

Which is then modulated and transmitted by means of RF (Radio Frequency).

Bugs are detected by virtue of the frequency signals they emit. Essentially a bug detector is a receiver. When brought near an operating bug, the detector will collect and amplify the bug’s transmission signals.

Bug detectors are now portable enough to be carried in a “sweep” of a room.

A detector recovers information of interest that is contained in a modulated wave.

The term ‘‘detector’’ dates back from the early days of radio use, when all transmissions were done in Morse code.

And it was only necessary to detect the presence of a radio wave using a device .

Such as a coherer without necessarily making it audible.

A more updated term would be ‘‘demodulator’’.

 A bug detector is a device that is able to locate and/or disables electronic spy equipment such as microphones, cameras, and GPS tracking devices. Law enforcement agencies, military counter-intelligence agencies, criminals, and everyday individuals who are suspicious of being overheard often use bug detectors. Bug detectors are usually small, portable, and have multiple display functions to alert the user to a “bug.”

 A bug detector is essentially a radio receiver that is able to pick up electromagnetic signals that are broadcasted from an electronic device or specifically, a bug. Rather than converting these intercepted radio broadcasts into data or audio, the bug detector simply lights up and sounds an alarm whenever it receives a strong frequency. By moving a bug detector around to nearby objects, it is able to alert the user to hidden bugs.

A small, portable Bug Finder can locate and often disable discrete microphones, cameras, cell phones and GPS trackers by keying to their electromagnetic signals or cellular activity using a small, portable and versatile radio receiver.

Strong frequencies trigger an alarm on the Bug Detector when intercepted and alerts the user to nearby hidden objects.

As long as you turn off all surrounding electronic products so as not to confuse the tuned frequency range, a slow walk around a room with a detector should out the locations the of any unwanted devices wherever they may be emanating from. Be advised, though valuable, other common electronic equipment from power lines to radio broadcasts can easily and often confuse a GPS detector.

RF Signal Detectors can home in on bugs as small as a penny using low radio frequency ranges between 1-3 MHz, comparable to a garage door opener. That may seem insignificant, but that frequency can capture any voice in a room as clearly as a phone tap or “wire” and leak damning personal and professional information.

One of the first things an electronic technician learns about is the famous “spurious emissions of radio waves”. In today’s world, we are surrounded by all types of “radio interference”. Many different types of “spurious RF” signals can be sought anywhere in a residence using any type of “Bug Detector” and can be misconstrued as a possible “RF Bug”, leading the sweeping individual into the wrong direction.

Radio interference that can be received from nearby:

– Radio Stations

– Television towers

– Amateur radio operators

– Cell towers

– 60-hertz wiring from a residence

– Fluorescent lighting

– Television sets and VCR’s

– Computers

– Power and Electrical Boxes

– and the list goes on…

Inexpensive “bug detectors” on the market are popping up all over the place. These are some of its features:

 – Frequency counters are sold as “Bug Detectors”. A frequency counter is designed to find the strongest single frequency of a transmitter. These counters in their nature are slow to respond, and will not find Spread Spectrum (frequency hopping) transmitters. The other factor is that these counters will display all “spurious emissions of RF”, giving results of different background readings of multiple frequencies.

This ever-changing display of frequencies only adds more to the confusion.

– “Bug Detectors” that feature the “little light” indication or “led indication” offer simple detection of radio frequencies in general.

  That feature a metronome noise or Geiger counter type pulsing noise, offer simple detection of RF.

Which can be any radio wave including spurious radio emissions.

– “Bug Detectors” that are so small they’ll fit in your pocket that do not include an antenna

Even some units that have a silent vibrating function.

Again, not allowing the user for identification of a real signal or background noise.
