Imagine you are an IT security consultant for pharmaceutical companies Miami Beach Coral Gables. Recently a company hired you to find out why their latest drug leaked to one of their competitors prior to release. The company has many labs in Miami Beach Coral Gables, each with sensitive drug information stored on computers that are closely monitored by cameras. The building they are housed in has security guards at every entrance and every employee is required to wear ID. Visitors must be escorted to ensure that no drug information leaks out in Miami Beach Coral Gables. Cell phone signal detector app

You meet with the head of security and go over the security procedures Miami Beach Coral Gables. After a little digging, you find that employee-owned electronic devices such as cellular phones signal are allowed in and out of the facility. The company Miami Beach Coral Gables feels that the non-disclosure agreements in combination with security personnel monitoring everything on camera are strong enough to keep employees honest and that the cost of screening for cell phone signals is too high. You tell the head of security that tomorrow morning security must seize every employee’s electronic signals as they enter the building Miami Beach Coral Gables. Cell phone signal detector app

The next morning you show up early and post yourself outside the entrance to the building Miami Beach Coral Gables. As people start to come into work their electronic signal devices are taken away. Eventually, you notice that someone walking up to the entrance immediately turns around and walks back to their car. You alert security and they find the person trying to stash away a cellular phone signal Miami Beach Coral Gables.

Later that morning, you download the contents of the cellular phone signal and find the files that were recently leaked. The employee confesses to everything and gives the details of how they did it. The files were stolen by transferring from the computers via a Bluetooth signal connection Miami Beach Coral Gables. Evidently, some of the computers came with Bluetooth signal and weren’t disabled by IT security. Using a Bluetooth connection signal didn’t look conspicuous on camera since there were no wires being plugged into the computer signal Miami Beach Coral Gables. Cell phone signal detector app

Therefore the company in Miami Beach Coral Gables needs a way to detect cell phones signal in the facility. There are a few existing cellular phone signal detectors apps on the market today that could get caught the employee prior to the information leaking out using a phone signal. However, this signal app Miami Beach Coral Gables still needs a lot of improvement and development.

Cellular Phone signal app detector Technology Miami Beach Coral Gables.

Cellular phone detector technology is rapidly changing. Features like Bluetooth, USB, high-resolution cameras, microphones, apps, the Internet, 802.11 wireless, and memory cards are added every year. Also, the communication technology a cellular phone uses such as CDMA, GSM, 3G, and 4G and apps are rapidly changing.

Cellular Phone detector Features Miami Beach Coral Gables.

Bluetooth is a secure wireless protocol that operates at 2.4 GHz and is used by some detectors Miami Beach Coral Gables. The protocol uses a master slave structure and is very similar to having a wireless USB port on your cellular phone detector Miami Beach Coral Gables. Devices like a printer, keyboard, mouse, audio device, and storage device can be connected wirelessly. This feature is mainly used for hands-free devices but can also be used for file transfer of pictures, music, and other data.

Universal serial bus (USB) is a way for cellular phones Miami Beach Coral Gables to connect to a computer for data transfer Miami Beach Coral Gables. This feature is very similar to Bluetooth for a cellular phone app with the exception of using a cable. On today’s cellular phone apps this feature is mainly used for charging the battery or programming by the manufacturer Miami Beach Coral Gables. It can also be used to transfer pictures, music, and other data.

Camera apps on cellular phones Miami Beach Coral Gables are a very popular feature that was added in the last 10 years. In recent years, high-resolution cameras have become a standard feature. Most cellular phones apps Miami Beach Coral Gables will come with at least a 2 megapixel camera and the more expensive phones can be as much as 8 mega pixels.

Microphones have been featured on cellular phones apps Miami Beach Coral Gables since they first came out. In the last 10 years the microphones have become dual purpose; now there are programs on the phone that record voice to file such as a simple voice recorder or as part of a video. Almost every available cellular phone today has a connection to the Internet.

This app Miami Beach Coral Gables allows users to transfer files and data wherever they are.

Cellular Phone detector app Communication Standards Miami Beach Coral Gables

Currently, the three main technologies used by cellular phone apps Miami Beach Coral Gables and providers are 2G, 3G, and 4G. Each generation of technology uses a different transmission protocol. The transmission protocols for apps Miami Beach Coral Gables dictate how a cellular phone communicates with the tower. Some examples are frequency division multiple access (FDMA), time division multiple access (TDMA), code division multiple access (CDMA), global system for mobile communications (GSM), CDMA2000, wideband code division multiple access (WCDMA), and time-division synchronous code-division multiple access (TD-SCDMA). All of these protocols typically operate in the 824 – 894 MHz band in the United States. Some protocols, such as GSM (depending on the provider) will use the 1800 – 2000 MHz band.

To provide a good example of how a cellular phone apps Miami Beach Coral Gables transmission works, take a look at Diagram 1 which shows how FDMA works. Each phone call uses a different frequency within the 45 MHz bandwidth. FDMA is normally used for analog transmissions and is capable of digital transmissions.

Secure Facilities using apps Miami Beach Coral Gables

Many app businesses Miami Beach Coral Gables for psychiatric hospitals, correctional facilities, pharmaceutical companies, government facilities, and military bases rely on keeping information protected. They build security fortresses that shield their money making information from getting to the general public using apps Miami Beach Coral Gables. These facilities have many computers that house the valuable information and are not connected to the Internet. Generally, access is restricted by guards with metal detectors and electronic devices are not allowed in or out without proper approval.

In every secure facility by apps Miami Beach Coral Gables it is hard to ensure that employees and visitors aren’t violating the policies. The only way to ensure someone isn’t carrying a cellular phone is to search everyone as they enter and exit. This requires a great deal of manpower and most companies can’t afford that level of security. Additionally, it will make the employees feel like the company doesn’t trust them.

Cellular Phone Detectors apps Available Today Miami Beach Coral Gables

To get a good grasp on what is available let’s take a close look at some of the shelf cellular phone detectors. Most detectors are manufactured with the intent that the cellular phone is stationary and powered on.

They generally have the same features and it is questionable whether or not they actually detect a cellular phone. The two most popular cellular phone detectors available on the market today are produced by Berkeley Varitronics Systems and Mobile Security Products. These companies produce the wolfhound cell phone detector and Cellbuster respectively.

Berkeley Varitronics Systems Wolfhound Cellphone Detector app Miami Beach Coral Gables.

Berkeley Varitronics app Systems Miami Beach Coral Gables wolfhound cell phone detector app Miami Beach Coral Gables will detect PCS, CDMA, GSM, and cellular bands using RF signatures. It also has the capability to directionally find or locate cellular phones that are nearby Miami Beach Coral Gables. The wolfhound app Miami Beach Coral Gables, according to the advertisement, can detect phones that are in standby mode, actively using voice, or data transmissions.

Wolfhound cell phone detector features:

  • 40 to a 50-foot radius of coverage. App Miami Beach Coral Gables
  • -60 dBm sensitivity. App Miami Beach Coral Gables
  • Audible alert App Miami Beach Coral Gables
  • Vibrating alert App Miami Beach Coral Gables
  • One-handed operation App Miami Beach Coral Gables
  • Continually scans for cellular phone uplink activity App Miami Beach Coral Gables
  • Integrated laser-assisted directional antenna App Miami Beach Coral Gables
  • Estimated battery runtime of 18 hours App Miami Beach Coral Gables

The Wolfhound on paper seems to be a great way to detect cellular phones, but may just randomly detect cellular phone communications in the area and not necessarily the phone or device that set it off. A couple of quotes from their advertisement simply this: “It took only two hours to find five cell phones that were either in use at the time or hidden in the jail cells in standby mode ready to take calls” and “With only 30 minutes of operation, the device can detect many cell phones and identify the positions which led the team to find 10 mobile phones.” These two quotes suggest that their device is picking up transmissions in the area, but it doesn’t show that they were directly from the phone they found or a phone at all.

Small print at the bottom of their advertisement reads, “Standby mode (autonomous registration) varies from base station to base station with phones typically registering between once every few minutes to up to 20 minutes. This time varies greatly based upon carriers, distance from base stations and individual handset manufacturer’s standards.” This again casts some doubt that their equipment is easy to use and won’t just be picking up random cellular transmissions or other devices in the area. Also searching the internet for reviews or feedback about the device produces no results. This uncertainty about whether the detector works makes the Wolfhound very similar to the Cellbusters cellular phone detector. Cell phone signal detector app

Cellbusters Cell Phone Detector app Miami Beach Coral Gables.

Cellbuster’s cellular phone app detector App Miami Beach Coral Gables provides continuous monitoring for cellular phones and has a voice alert that tells the user to shut their phone off if detected. The Cellbuster only receives and doesn’t transmit, making it great for areas sensitive to cell phone usage. It will also detect phones that are in standby mode. Cellbusters cell phone detector features:

  • Detect and prevent unauthorized cell phone usage.
  • Detects analog and digital cellular phones CDMA, TDMA, GSM, and PCS/PCN types
  • Range adjustment
  • Audio alert asks cellular phone users to switch off their phone
  • Red alert light flashes brightly to attract attention.
  • Detects when a phone is switched on and not in use
  • Easy to configure and simple to install

This cellular phone detector app Miami Beach Coral Gables sounds like it would work wonderfully for keeping people from bringing their phones into a secure facility. However, the advertisement isn’t very honest about the detector app Miami Beach Coral Gables. It doesn’t tell you that a cellular phone may take up to 20 minutes to detect if it is on standby and that the phone needs to be on App Miami Beach Coral Gables. Also, just like the Wolfhound, it doesn’t provide any guarantee that it won’t just detect random transmissions in the area using the app detector App Miami Beach Coral Gables.

To show how inaccurate today’s cellular phone detectors apps are App Miami Beach Coral Gables, a Cellbusters detector app Miami Beach Coral Gables was borrowed from a local business and tested as part of this study. Using two LG VX11000 GSM cellular phone app Miami Beach Coral Gables, this cellular phone detector was tested extensively. Following is a synopsis of the testing:

Test 1 – Outside Faraday Cage at Home with Cellular Phone app Turned On App Miami Beach Coral Gables

 

  • Tried cell detector sensitivity set low and high for 20 minutes each – detector didn’t activate. Detector app Miami Beach Coral Gables
  • Called one phone from the other and left on for 5 minutes – detector didn’t activate Detector app Miami Beach Coral Gables
  • Texted one phone from the other – detector didn’t activate Detector app Miami Beach Coral Gables
  • The detector doesn’t appear to work in public area with the sensitivity set high or low. Detector app Miami Beach Coral Gables
  • Detector activated randomly and generally not during a phone call. Detector app Miami Beach Coral Gables

Test 2 – Inside Faraday Cage at University of Nebraska Omaha with Signal Generator Set to 832 MHz. Detector app Miami Beach Coral Gables

  • Tried cellular detector sensitivity set low and high for 10 minutes each – detector didn’t activate.
  • Tried varying the frequency from 100MHZ to 1GHz – detector didn’t activate
  • When set to high and open Faraday cage door it would alarm sometimes.

Testing this cellular phone detector led to a few conclusions. The Cellbusters Cellular phone detector doesn’t work very well and it is questionable that the detector works at all. Using this device in a public area the detector just randomly went into alarm and didn’t indicate where to go or what to do. Testing indicates that the Cellbusters cell phone detector doesn’t work as advertised.

To get an idea of the circuitry required to build a cellular phone detector, it was dismantled.

After taking a close look at the circuitry used, no conclusions were drawn on exactly what technique of signal detection was used. Cellbusters most likely used some digital signal processing to identify the signal characteristics of a cellular phone. A study performed by the U.S. Department of Energy pointed out that 2 of the 5 reviewers of the product reported that it didn’t work. In October 2007 when the study was performed, the Cellbusters Cellular phone detector cost $755 each and was back-ordered. Cell phone signal detector app

Related Work for detectors.

Since cellular phone detection is a more recent problem, there are only a few articles that have already researched this area. Two articles were published in 2007 and provide good analysis. The first article, “Detecting and Locating Cell Phones in Correctional Facilities,” was written by EVI Technology, LLC. The second article, “Cell Phone Detection Techniques,” was written by a Contractor hired by the U.S. Department of Energy (DOE).

Detecting and Locating Cell Phones in Correctional Facilities using a detector.

This article details the growing problem with cellular phones in correctional facilities and lays out the constraints used to develop their solution. According to the research, cellular phones in a correctional facility are used to operate criminal enterprises, threaten witnesses, harass victims, plan uprisings, and undermine security. Their problem is monitoring, controlling, and locating cellular phones in a correctional facility. Cell phone signal detector app

EVI’s possible solutions include physical search, non linear junction detectors, signal jamming, shielding, network provider location based screening, RF detection, and their custom proprietary solution. They rule out all solutions but their own custom solution that uses a system of networked sensors that are controlled by a central computer. EVI uses proprietary software that determines the cell phone’s location and detects any RF emissions. The location of detected cellular devices is displayed on a facility map.

This solution was developed for detecting cellular phones in a prison. It relies on the cellular phone remaining stationary which, in prison facilities makes sense since movement is limited. EVI’s detection system finds cellular phones after they have already been in the facility for at least 30 minutes or if someone is making a cell phone call. EVI doesn’t provide any details on the signal detection technique used since it is all proprietary. Also, there are no reviews or articles stating that this system works as advertised.

Cell Phone Detection Techniques and apps Miami Beach Coral Gables.

 

This study examines detecting cellular phones when a person is entering a secure facility or cellular phone restricted area. The detection technique using apps Miami Beach Coral Gables studied requires measuring a cell phone’s electromagnetic properties and determining an identifiable signature. Measuring the RF spectrum around 240 – 400 MHz (outside the cellular phone band) shows the most potential. Cell phone signal detector app

The DOE Contractor recommends developing a cellular phone detector by measuring the RF spectrum. Spurious emissions from cellular phones are monitored and recorded when the phone is in standby or transmitting. Using this method has some advantages:

  • No external signal required for detecting the phone using a detector
  • The band of frequencies is limited by the FCC and are likely to be used by most manufacturers.
  • System could potentially detect more than cellular phones using a detector
  • This method should work on future generations of cellular phones
  • The system could potentially detect cellular phones even when they are off.

Bugs are detected by virtue of the frequencies they emit. Essentially a bug detector Miami Beach Coral Gables is a receiver. When brought near an operating bug, the detector Miami Beach Coral Gables will collect and amplify the bug’s transmission. Bug detectors Miami Beach Coral Gables are now portable enough to be carried in a “sweep” of a room. Cell phone signal detector app

Most bug detector Miami Beach Coral Gables are able to track almost any wireless spy device that uses RF signals. Be it a wireless mini hidden camera, a phone bug, or a Bluetooth spy cam.

But, detecting hard-wired cameras was a little problem. It’s simply because they don’t use radio frequency signals to transmit data between the transmitter and a receiver. Now, powerful bug detector Miami Beach Coral Gables devices can spot even wired CCTV cameras in the area. So the main problem is simply gone with these new-era bug trackers. Cell phone signal detector app

How Bug Detector Miami Beach Coral Gables Work

A bug detector Miami Beach Coral Gables 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 Miami Beach Coral Gables simply lights up and sounds an alarm whenever it receives a strong frequency. By moving a bug detector Miami Beach Coral Gables around to nearby objects, it is able to alert the user to hidden bugs.

Fortunately, most radio frequency bugs are easily found by detector Miami Beach Coral Gables. The signals that they transmit are fairly common and can be spotted by a simple device tuned to the frequency range that the offending bugs use. Simply make sure all electronic products are turned off in the space you are checking and slowly walk around the room. If an offending radio frequency is operating in the room the device will pick it up and notify you. Cell phone signal detector app

Types of Bug Detector Miami Beach Coral Gables and where you can buy them

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. Cell phone signal detector app

Many detector Miami Beach Coral Gables cover from 50 MHz – 6.0GHz. This covers the normal frequencies that wireless devices use. 50 MHZ (megahertz) is the low end of the scale this is where you will find most voice transmitters. As you move up the scale to the GHz (gigahertz) you get into the wireless camera frequencies. MHz and GHz are just frequency denominators IE: 1000 MHZ is equal to 1 GHz so a 2.4 GIG camera can also be considered to be a 2400 MHZ and a 5.8 GHz can be a 5800 MHZ. Cell phone signal detector app
