How Many Surveillance Cameras in London?

Surveillance cameras have become normal in the UK. Wherever you go, if you're keen enough, you'll notice that there are always cameras recording your movements and actions. Additionally, you may even have a private investigator's camera on you without ever realizing this.

London is one of the most heavily surveilled cities in the world, and that doesn't include the work done by private detectives. Every day you're out and about, your movements are captured on dozens of cameras. In case of anything, a private investigator or law enforcement officials may be able to review this footage to see what you have been up to.

Reasons For Heavy Surveillance In London

Apart from private investigators, there are many reasons why different parties have decided to put up surveillance cameras in their buildings or outside their buildings. Common reasons include:

  • As a form of deterrent for any potential criminals
  • To see who is outside the building before allowing them to enter
  • To prove to certain parties that the building is secure

However, much of the surveillance in London is down to the constant threat of terrorist attacks. Surveillance cameras can assist investigators to thwart terrorist attacks by allowing them to monitor locations or persons of interest. The surveillance footage can also help with investigations after an attack which can be vital in stopping future attacks.
