San Francisco Opera House and Symphony Hall to Install New Weapons Detection System

The San Francisco War Memorial and Performing Arts Center, which manages the city’s Civic Centre theatres and concert halls, is introducing a new weapons detection system at the War Memorial Opera House and Davies Symphony Hall.

The roll-out will begin in September, with the aim of enhancing security while minimising disruption to performances and the audience experience. The War Memorial’s three resident companies — the San Francisco Symphony, the San Francisco Opera and the San Francisco Ballet — will implement the system in stages. It will go live at Davies Symphony Hall on 4 September and at the Opera House on 14 September, with other locations to follow later.

The system uses sensors and artificial intelligence to detect threats. It emits extremely low-frequency radio waves to gather data, which AI algorithms use to distinguish between everyday items and potential weapons. If a threat is detected, visual and audio alerts are sent to security personnel via connected tablets, indicating the person and the approximate location of the potential threat.

More than 50 arts and entertainment venues — including New York’s Lincoln Center, the Lyric Opera of Chicago and the Hollywood Bowl — are already using the system. The War Memorial praised the technology for enabling “frictionless entry”, allowing patrons to enter without stopping, emptying pockets or opening bags.

San Francisco Opera’s general director said audience and staff safety was paramount, describing the technology as a vital upgrade: “It ensures the War Memorial Performing Arts Center remains a leader in the American performing arts not only for the quality of its stage productions, but also for its audience experience.”

The system was delivered in late July and will be tested in August. Each entrance can screen up to 3,000 people per hour. The first-year budget for equipment and maintenance covering eight lanes is $140,000, followed by $125,000 annually for the next three years. The Centre described the shared investment as a worthwhile measure to optimise security and enhance the visitor experience.

“It’s no wonder more and more organisations are adopting this system — safeguarding the security and peace of mind of audiences is priceless.”
