ARGUS, demonstration specimen. Darkvalley R&D.
Darkvalley R&D, SASU. Contact: patron.julien@darkvalley.fr. The site is hosted on a server rented in France.
A demonstration specimen, not a service in operation. It runs on an invented venue, "The Last Opera", whose zones, equipment and incidents are fictional. It drives no installation, receives no real data, and is connected to no PLC.
It collects nothing and sends nothing. No account, no form, no audience measurement, no advertising tracker, no request to any third-party service. The whole page is a single file served from this server.
A few things are written to your browser's local storage, on your device: the current view, the density and display mode, the fact that the access code has been entered, and three interface preferences shared with the other Darkvalley tools (background intensity, economy mode, no animation). Nothing else. These values never leave the device and are erased along with the site's browsing data.
The state of the demonstration itself is not kept: it is rebuilt on every opening by a reproducible generator.
The demonstration opens with a code. It is a courtesy barrier, not a security measure: the code is contained in the page, like everything that runs in a browser. Nothing confidential lies behind it, and that is deliberate.
The demonstration broadcasts no video feed: no camera is connected, no video is loaded. The camera views illustrating the article are computer-generated images of an invented venue, produced by a generative tool: they represent no existing place, and no real person appears in them. The figures seen in them correspond to nobody.
In a real installation, ARGUS shows no more video feed than here: it indicates which camera to look at on the CCTV system already in place, which remains the operator's responsibility, with its own obligations regarding notice to individuals, retention period and access restriction.
For the avoidance of doubt: ARGUS is a supervision and informationtool. It carries no safety function, neither in this demonstration nor in an installation. Emergency stops, interlocks and detection devices are the province of the safety PLC and of the venue's regulatory systems, which remain in charge in all circumstances. The safety states shown in the interface are read-only reports.
"The Last Opera" is a venue invented for the demonstration. Its theme draws on the novel The Phantom of the Opera by Gaston Leroux, published in 1910 and in the public domain. No element specific to a later adaptation, theatrical or cinematic, is used: no derivative work title, no character as redrawn by those adaptations, no visual identity.
