Police have asked people to look at the footage of their Ring doorbells to try and track down a missing couple.
Merseyside Police want to trace the whereabouts of Murat, 50, and Ayten Gurbuz, 47.
Their family have become concerned after they vanished from Birkenhead, Merseyside.
Police were contacted by concerned relatives, who live in Turkey, saying they have not heard from either of them, the Liverpool Echo report.
Their last known address is a flat in Grange Road in town and police are appealing for people in the area to check any CCTV or doorbell footage for the pair.
They have also released an image of the couple and have asked anyone with information to come forward.
