If you've ever watched an episode of Casualty or ER on the television you'll appreciate the pressure that hospital accident and emergency staff work under and the array of people who pass through the doors.

Well Bradford Royal Infirmary, the third busiest a&e department in the country, has protected its staff and patients from unauthorised entry and attack with a door entry system from BPT Security Systems UK.

The £250 000 installation by Centurion Security is a video door entry system. It includes stainless steel panels with built-in video monitor, loudspeaker and microphone to provide staff with a view of the visitor and two-way communication.
