Photos: Computer saves drowning girl
Monitoring system springs into actionThe girl sinks to the bottom of the deep end of the pool, one of the deepest in Wales
But as she drops the rest of the swimmers above remain unaware of the crisis below
The system springs into action within three seconds, viewing her from a number of different cameras
The monitoring system pinpoints her on the bottom of the pool
The lifeguard, alerted as to where the girl is, dives in…
…and pulls her back to the surface to be resuscitated.
