This may sound like something straight out of an episode of Black Mirror, but police surveillance via facial recognition drones has already become a reality in the Middle East.

Police in Sharjah, the third-most populous city in the United Arab Emirates, are using drones with facial recognition technology to track wanted criminals. The law enforcement agency is leveraging a video surveillance network powered by artificial intelligence for this task, according to a report published in Gulf News today.

Here’s how the technology works: Once a felon’s photograph is fed into the AI network, facial recognition drones take to the skies and scan crowded public spaces. When a drone suspects it has spotted a target, it captures his or her images – possibly flying lower and adjusting the gimbal for a better angle.

Machine learning models then scan the images for instant analysis. If any matches are found, the ground units of the police force move in to make the arrest.
