The picture surveillance system provides security for all works of art suspended on walls in museums and galleries. The system signals alarm when the object is touched, moved or removed, thus guaranteeing optimum surveillance, especially when the gallery is open to the public.

The BM41 triggers an alarm when the object is lifted from the hook.
