FRANCE (REUTERS) - It could be the future of public security.

A new mobile phone app, Reporty, is being tested in the French Riviera city of Nice.

2,000 people are trying out the service which allows them to record and report crimes to police in a matter of seconds.

Geo-locating and video streaming allows police to see exactly where someone in, and what is happening around them straight away.

And police say that will help them be more efficient at processing huge numbers of calls.

"The point of the app is to help us manage the number of calls we get at the surveillance centre, we have to manage 75,000 calls a year. And the difficulty of these calls often for us is to figure out the location of the callers in order to send teams to them, and also to get precise information," said Nice Municipal Police Command and Operations Centre Deputy-Director, Christophe Gardon.

The city is best known as a sunshine magnet, but it is equipped with more surveillance cameras than any other city in the country.

Despite that, Nice was hit by a devastating attack in July of 2016.

When an Islamist militant killed more than 80 Bastille Day revelers when he drove a truck down the city's iconic promenade.

Now local police are hoping 'Reporty' will shut down any further attacks and change the face of crime reporting.
