Wilsons Detectives Nationwide Investigations provide a wide range of surveillance services throughout the UK and abroad. Surveillance is often an important element in many aspects of an investigation. Our agents with previous military and police surveillance experience have available the latest 'hi-tech' covert GPS Real-time tracking devices, video and photographic equipment. For mobile operations, a team of at least two operatives will typically be deployed, allowing for one car driver and one footman. For surveillance in urban areas, an additional footman is often required, this will rule out any chance of the target escaping by taking another from of transport such as the Underground or a Bus. If static surveillance is required, one operative in a surveillance vehicle will usually suffice, but if there is no suitable location for parking a vehicle, two or more foot operatives may be needed.
