Tracing a Missing Person

Every year over 200,000 people are reported missing in the UK. In the event of your spouse, child, or friend going missing, a private investigator can be hired to find them.

A private detective will first talk with family, friends, and witnesses to establish a background story. Then they will use a number of resources such as public and private records, the internet and social media.

The best place to hire a private investigator would be the capital city of London. A London private detective are some of the best in the country and have immediate access to the largest city in England – the perfect place to go missing in.

When looking for a London private investigator, it's worth considering the advantage their local knowledge and contacts brings to any case where the person may be thought to be in the capital.

Bug Sweeping London

Bug sweeping - or as it's more correctly known - Technical Surveillance Counter Measures (TSCM) is the use of specialist equipment and skills to find and remove devices, nicknamed bugs, that monitor peoples communications or conversations.  As a major global commercial and commercial centre, bug sweeping London is a major task.

Bug sweeps are carried out by private investigators and companies that have the right specialist equipment and expertise.  Bugs are actually a whole range of devices that carry specific tasks such as:

Audio listening devices.

Audio recording devices.

Cameras for visual monitoring.

Wire tapping devices to listen in on telephone Calls.

Electronics devices to intercept data on computers, servers and networks.

The bugs are intended to collect information covertly, i.e. without the people under surveillance being aware of it, so they tend to be very small and discrete.  They are also designed to be difficult to detect, even if you have the right equipment.  This is why, for all the technical sophistication of the industry one of the most effective forms of bug sweeping is still the use of an experienced investigator with a ladder and a torch.

So, TCSM in busy cities such as like London is defined as the electronic and physical examination of a particular location by qualified and experienced staff with the aim uncovering eavesdropping devices and any flaws in the security systems.

RF Type Bugs

Most bugs have to transmit the information they collect air using radio waves.  The best way to detect these particular devices is to use a radio frequency (RF) receiver. RF kit is expensive and needs a sound understanding of RF theory in order to really track down devices.  This is because bug designers are getting very adept at including detection counter-measures such as burst transmission and spread spectrum transmissions.

Other Bug Types

One way for bugs to evade RF detection is simply to record data rather than transmitting it.  This places a limit on the amount of data the bugs can collect, and whoever planted them has to have some way of retrieving the information, but they are hard to detect using technical equipment.  Another option is to use very sensitive equipment that can detect the small magnetic fields that such devices still emit, but this can also be difficult when magnetically “louder” equipment, like computers, photocopiers, Wi-Fi equipment and phones, is also in the area.  For these devices a thorough physical search is still the best approach.

Yet another method of detecting bugs is the use of extremely sensitive thermal imaging cameras that can detect the tiny level of heat a bug, or its power source, will create.  This method is really good for bugs that have been hidden in wall or ceilings.

Bug Sweeping London

The technology and equipment used for a bug sweep includes:

Electrical Multi-meters - which detect the power supplies and components of eavesdropping devices.

Time-domain reflectometer (TDR) - this device tests copper telephone and comms. cables and checks for interference that may suggest that a bug is present.

Frequency scanner - used to detect the radio signals that are emitted by bugs.

Oscilloscope - to allow the investigator visualise signals, which helps to spot patterns and signals that should not be there.

Spectrum analyser and vector signal analyser -  for the advanced analysis of RF signals.

Nonlinear junction detector (NLJD) - detects the components associated that are included in eavesdropping devices.

Portable x-ray machine - to check inside objects and walls that are not possible to dismantle for checking.

Computer security devices and tools to detect computer related eavesdropping.

Thermal imaging camera - to find the "hot spots", even tiny ones, generated by active electronic components.

A full toolkit, torch and ladder -  to reach and dismantle items to look inside for bugs.

This is far from an exhaustive list bug sweeping equipment, but it does cover the kit used in the vast majority of searches.

Not Just A Private Investigator In The Sky – The Reaper

As London private investigators and detectives we take surveillance seriously.  Much of our time is taken carrying out bug sweeps for people who find themselves under surveillance for one reason or another, so we have to know about the type of equipment that people use to carry out this unwanted and often unscrupulous task. 

The equipment we use to do this is very up to date and sophisticated, but it doesn't begin to some of the Hi-Tech equipment the military has at its disposal.  A great example of this is the Reaper, a space age drone that takes surveillance in to the skies and over the horizon. 

For governments, and in particular the military, it's crucial to know what the other side is up to so you can get ready to deal with whatever might come your way.  This need to extend the view of the world around us an has long been a driving factor in the development of surveillance equipment, and the corresponding counter measures to try and keep the other side from finding out their our own secrets. Over the last 50 years advances in technology, miniaturisation and computers has led to huge improvements in how far we can see and hear, and an outstanding example of how effective this can be is the General Atomics MQ-9 Reaper.

Eyes, Ears and Mean Punch

The Reaper is a drone, or an Unmanned Aerial Vehicle (UAV) to use its proper title.  It was developed by the aviation company General Atomics Aeronautical Systems for the US Air Force, and is designed to carry out long endurance high altitude surveillance flights, and where necessary attack targets that are seen as a threat.  This is a development from it's predecessor, the Predator, which was primarily a private investigator in the sky, looking and listening to what was going on around it.  The Reaper carries significant weapons load that allow it to tackle many of the situations it uncovers without the need to call in additional fighter aircraft. 

The drone is remotely operated by pilots who are based in what is known as a Ground Control Station.  This can often be thousands of miles away from where the drone is flying, making it a truly remarkable aircraft.  The Drone can be flying around the skies in Afghanistan while the controller is sitting in an air conditioned room somewhere outside London.  In 2008 the United States Air Force began converting fighter squadrons to operate the drones, and by 2011 they were training more pilots to fly the UAVs than any other type of aircraft.  The Reaper is also used by the US Navy, the CIA, US Customs and Border Protection and NASA, as well as several other countries around the world.

Technical Capability

Operators can investigate installations, look for targets and look at the surrounding terrain using a number of sensors carried by the drones.  These include a thermal imaging camera and optical cameras, one of which is can read the number plate of a vehicle up to two miles away.  The fast satellite link between the pilots and the drone mean commands take as little as 1.2 to travel between them, giving almost instantaneous response and feedback of the information.  

The drone can carry weapons or additional fuel tanks under its wings, giving a range of options to commanders.  The aircraft can carry anything between 450kg of munitions for up to 42 hours and 1350kg of munitions for up to 14 hours.  The munitions include the Paveway laser guided bomb, Hellfire air-to-ground missiles and Sidewinder missiles.
