You can't see it, but it's there, watching your every move.

Troublemakers have been singled out by the Panomera Multifocal Sensor System.

In February last year, Mr Axel Hellmann, executive board member of German football club Eintracht Frankfurt, told German newspaper Bild that the identification of 15 offenders at a fireworks riot was possible thanks to Panomera.

He said the images that led to the arrest of the rioters were razor-sharp.

What is crucial to Mr Bernhard Niesen, head of stadium operations at Borussia-Park Monchengladbach, is the immediate sharing of positive identification of suspects with the police.

He had told German security portal in 2012: "Because of the high resolution, we are able to take a passport photograph of the offender, even from 100m away."

The New Paper was given a demonstration by Mr Jensen Quak, sales manager of Dallmeier International (Singapore), at Stadia & Arena Asia Pacific 2014 in September.

He showed how the Panomera system could render correctly-exposed image even when half of it was exposed to sunlight and the other in the shadows.

The details were sharp and, at 30 frames per second, the recorded movements of subjects looked natural.

It is understood that some variants of the Panomera cameras can "recognise" subjects from 250m away.

How does Panomera achieve this?

Mr Quak explained: "The Panomera is a multifocal system, which means it has lenses that focus at different distances, and we are able to combine these lenses' images into a single overview scene.

"It is this technology that allows us to have unsurpassed resolution performance at long distances."
