In an irony so sharp it could cut glass, the Magna Carta—the foundational document of Western democracy and human rights—is now being watched over by surveillance cameras manufactured by a Chinese firm accused of facilitating genocide.

Human rights campaigners have raised a furious alarm over the installation of CCTV cameras made by Dahua Technology at Salisbury Cathedral, the sanctuary housing the best-preserved copy of the 1215 charter. The revelation has sparked a diplomatic and ethical firestorm. Dahua, along with its rival Hikvision, has been blacklisted by multiple Western governments for its alleged role in the surveillance infrastructure used to oppress the Uyghur minority in Xinjiang. Yet, in the quiet Chapter House of Salisbury, these same "eyes" are entrusted with guarding the very parchment that first codified the principle that power should not be absolute.

The Ethics of Security

The decision by the Cathedral’s security contractors, ARC Fire Safety & Security, was driven by technical specifications—low-light performance to protect the ancient ink—but it has collided head-on with geopolitical morality. Critics argue that paying for this technology makes the Cathedral complicit in the company’s wider activities.

• The Uyghur Connection: Big Brother Watch and the World Uyghur Congress have slammed the move, pointing out that Dahua’s facial recognition technology has been marketed specifically for its ability to identify Uyghurs, a tool for ethnic profiling.
• The Security Risk: Intelligence agencies in the UK and US have already banned these cameras from sensitive government sites due to fears of "backdoors" that could allow Beijing to access the footage remotely.
• The Symbolism: "You cannot protect the symbol of freedom with the tools of repression," said a spokesperson for the campaign group Don’t Fund Russian Army, which also highlights the use of such tech in the Ukraine war.

A Cathedral in a Bind

Salisbury Cathedral finds itself in an unenviable position. The Magna Carta is a priceless artifact requiring state-of-the-art protection. The Dahua cameras were selected for their ability to operate in under 10 LUX of light, preventing damage to the document. The Cathedral argues it is prioritizing the physical safety of the charter. However, the optics are disastrous.

This controversy exposes the deep penetration of Chinese surveillance technology into the West’s critical infrastructure. From schools to cathedrals, the cheap, high-quality hardware has become ubiquitous. But as the world bifurcates into rival technological spheres, institutions are being forced to choose sides. The "silent sentinels" in Salisbury are no longer just cameras; they are political actors. As pressure mounts, the Cathedral may be forced to rip out the system, proving that in the modern world, even a medieval charter is not safe from the complex web of 21st-century geopolitics.
