As Brazil prepares for the 2014 World Cup, police is looking for more effective methods of tackling crime. Recently it was unveiled that the local police will wear special glasses equipped with facial recognition technology to help spot troublemakers.

The glasses will have a built-in tiny camera that will be able to capture 400 facial images per second. The images will then be transmitted to a central computer database.

It would be interesting to note that the new system is able to compare biometric data at 46,000 points on a person's face and if it identifies a known criminal it will instantly signal the police officer by turning on a red light on the small screen linked to the glasses.

Soon the invention is going to be tested at local soccer matches and concerts. It is worth mentioning that the camera will be able to scan faces in crowds up to 50 meters away. However, if the police are searching for a particular person, the camera can be adjusted to be able to identify faces that are 12 miles away, reports The Telegraph.
