Fans of the British royals must make a note of 6 May 2023: On that day, the coronation of Charles III will take place in Westminster Abbey. The ceremony is apparently to be smaller than that of his mother's coronation in 1953. A modern security concept is indispensable today for public buildings or events such as the coronation of King Charles the 3rd. ZEUS® Access control by ISGUS reliably ensures security against unauthorised access around the clock to protect your employees, visitors, data, know-how and to protect your buildings and operating equipment. The electronic locking plan shows at all times who is authorised to open certain doors or who is allowed to pass through certain sections of the building.
