Private detectives usually use surveillance equipment without the knowledge of the subjects being observed. This is done to gather information such as videos, photographs, or data of a person’s activity. Hiring a professional Private Detective in London from the best PI firm will ensure that your investigator uses these advanced gadgets and electronics for an extensive surveillance.
1) Audio recording devices
Private investigators use forms of covert audio listening, recording, and analysis equipment to capture conversations and sounds to be used as evidence in investigations. An investigator might use a digital voice recorder / audio recorder with amplified microphones to record witness or subject statements, record notes about a case and more. Other audio analysis tools such as voice analysis and modification tools, voice stress analyzers, voice changers, and transformer instruments work with telephones and cell phones.
2) Cameras and video-cameras
Taking photographs and capturing video footage has become one of the most pervasive types of surveillance. Investigation professionals use upgraded high-tech cameras and video-cameras to click pictures and capture hidden videos. The photographic evidence or video footage can become official evidence in a court trial.
3) Binoculars and optics
Binoculars are a must-have piece of surveillance equipment for private investigators. Night vision goggles and night vision binoculars are useful for night time sleuthing and security.
4) Computer hardware and software tools
A competent investigator from a reputed UK private investigation agency will use specialized hardware and software programs to spy on computers, record internet surfing, and other computer activity to capture chat conversations and email exchanges. A PI may use key-logging software to catch a cheating spouse who is chatting online with another partner.
5) GPS tracking device
A skilled private investigator uses covert GPS tracking devices to track the movement and travel activities of just about anything, from vehicles, to people and physical items. The trackers monitor the movements using specialized software that uses GPS signals to track the exact location of the device.
Private investigators often need to listen to conversations from a distance, so they use electronic listening devices, headsets and headphones.
