Kameror och ett bildanalysprogram räddade livet på en 10-årig flicka i North Wales.
The 10-year-old girl lost consciousness in the deep end of the Bangor Swimming Pool, North Wales, last Wednesday and dropped quickly to the floor of the pool, 12ft 6ins under the surface.
Within 10 seconds, one of four underwater safety cameras spotted the girl and alerted lifeguards via a pager message. A lifeguard dived into the water and pulled the girl to safety. She was given mouth-to-mouth resuscitation and made a full recovery in hospital
