The Terracotta Warriors Museum is protected with Bosch intrusion technology

World Heritage, the mausoleum of the first emperor of China, protected by these clay warriors, It has powerful fail-safe detectors, to warn of the entry of thieves and possible damage to the sculptures.

He Mausoleum of Emperor Qin Shi Huang, UNESCO World Heritage Site, located in Xi'an (China), houses an army of 2000 years old made of clay statues, the Terracotta Warriors, that guard the tomb of the first emperor of China.

With an intrusion detection system that had become obsolete, One of the priorities has been to update it and address several key challenges in terms of security.. one of them was, until the arrival of the pandemic, was to respond to the high volume of thousands of daily visitors with a rapid alarm system, fail safe, if the exposed elements are in danger.

In addition to the constant risk of possible thieves trying to steal the displayed items, the biggest threat comes from tourists, those who drop mobile phones and cameras into ditches, exceed the limited areas and the possible damage they cause.

Another challenge was that the new solution had to work in extreme conditions, since the pits, which house several thousand clay warrior statues, contain large amounts of dust that can impede the work of the detectors. Finally, the system had to be discreet, without interfering with the experience of observing the full-scale warriors and horse statues.

With these challenges, Bosch experts developed a combination of several hundred intrusion detectors in the 16.300 m2 of museum area. In order to achieve rapid detection of security flaws, wall-mounted detectors were installed along the pits, which was complemented by those installed on the ceiling, above areas where visitors pass and those that are open.

The detectors, integrated into manufacturer's G Series control panels, They operate with microwave and infrared technologies, enhanced by First Step processing algorithms (FSP) to detect changes in infrared energy when a person exceeds a predefined safety limit inside the museum and along the perimeter.

By eliminating false alarms due to dust and other environmental interference, The pit detectors use a pyroelectric sensor with infrared (PIR) and adaptive microwave noise processing technology.

A differential feature is that the sensors provide accurate intrusion detection, although they are mounted on the high, vaulted ceiling of the Terracotta Warriors Museum. Specifically, the ceiling is 4,8 m high, which exceeds the limits of standard ceiling detectors by more than 2 m.

In the event of an intrusion attempt, Bosch G Series control panels activate an alarm in the museum control room in just two seconds. In addition to the exact location of the detector, The security team receives real-time images of the scene from a surveillance camera, thanks to the integration of a third-party video security platform, for a quick and effective response.

The integrated security system also answers another key requirement for museum operators: taking into account that a large part of the pieces exhibited are stored elsewhere when necessary, which in turn must be safeguarded from thieves, Bosch detectors protect these storage facilities .

Thanks to this use of detectors, costs are not only saved on surveillance personnel for these spaces., that are protected from intrusion and damage, But visitors enjoy a personal experience by contemplating ancient objects without any type of fences or barriers that limit their journey..
