The system developed in Turkey uses webcams to track a person's eye movements and can then produce an edited reel of footage that they didn't see at the end of their shift."

Privacy campaigners may enjoy the irony if the gaze-tracking system comes to be regarded as intrusive by CCTV operators – who could fear that employers will use it to dispense with their services if they consistently miss too much on-screen skulduggery.
