Britain’s Metropolitan Police Service cracks an average of six crime cases every day using CCTV cameras.

Using CCTV cameras, the Metropolitan Police Service identified 2,512 suspects during 2010, up from 1,970 suspects in the previous year. Those identified using CCTV cameras include, 574 robbery suspects, 427 burglary suspects and 23 suspected sex offenders.

Detective chief inspector Mick Neville said that they were treating CCTV images like fingerprints and DNA to identify suspects.

Speaking on the topic, Mr. Neville said, "The key to our success is that images, unidentified images, are treated as a forensic discipline. They are treated like fingerprints and DNA."

CCTV cameras have become a ubiquitous feature on the UK streets. The number of CCTV cameras has been pushed up from 21,000 in 1999 to 59,753 this year.

CCTV cameras have been making it easier for the police service to identify suspects, but some campaign groups, such as Big Brother Watch, have been criticizing the increase in the number of CCTV cameras.

Nevertheless, CCTV cameras are very important in fight against crime because they capture and later reveal what actually happened at a particular spot.
