ArtRatio Operating System (AOS)

Control and Monitoring System for Display Case Manufacturers

The ArtRatio Operating System is a patented, IoT, hardware / software solution that can be embedded into display cases to provide monitoring, lighting and cloud-based data analytics.

ArtRatio Operating System - Intranet Dashboard

Minimise Risk of Damage

Monitor temperature, humidity, light and light exposure in real-time and historically. User-configurable alarms are flagged for your attention. The ArtRatio Index of Risk estimates damage based on the sensitivities of the materials on display.

Monitor Popularity & Visibility

The ArtRatio Index of Popularity monitors how long (and at what time) the items have been viewed, indicating visitor engagement per vitrine and helps to optimise their physical positioning. The ArtRatio Index of Photopic Visibility estimates how well details and colours are visible to people of all ages.

Prove Good Ownership

Improved art condition protects its market worth. The ArtRatio Index of Value helps collectors to protect their investment in art, at the same time enhancing their own reputation. Insurers may reward such good behaviour by lowering premiums, since their income depends on the item’s market value.

Virtual & Physical Visits

All data is time-stamped and pushed in real-time to the ArtRatio Cloud, allowing custom reports to compare virtual visits (on the item’s webpage) to physical visits (to the item itself) and eventually to sales of the item. This can drive sponsorship and funding for institutions, and provide engagement metrics for retailers.


LED spotlights


We currently provide 2 channels of LED lighting, as well as 4 parallel channels of dimming output, suitable for PDLC or SPD smart glass, allowing control over light levels inside the case, from 0 Lux to any value your collection will accept.

Both the LEDs and the smart glass can be manually – or automatically – controlled from the ArtRatio Intranet, based on the sensitivity of the materials on display.


The AOS incorporates sensors to measure temperature, relative humidity, light intensity and light exposure, as well as a reflective IR proximity sensor.

Instead of just providing raw data, the Intranet gives users meaningful information, based on the conservation needs of the collection.

Cloud Connectivity

The AOS connects by default to the supplied ArtRatio router over WiFi which can connect via 4G or via your own infrastructure network to the public internet.

All data is time-stamped and pushed to the ArtRatio Cloud, providing remote, secure visibility, anytime and anywhere in the world.

Why does a display case need an operating system?

Just as cars, phones and TVs now typically have operating systems to integrate their functionality, it makes sense to copy that model to the humble display case.

The AOS brings together all the functions a display case typically needs, such as sensors, lighting and connectivity, into one cohesive unit.

  • No more ‘after-thought’ sensors placed in the corner of the display case.
  • No more manual data loggers that only connect via USB.
  • No more lighting that offers only manual dimming.

The AOS integrates all these functions from the start, beautifully enhanced by our software that converts the raw data into information that is meaningful to the collection.

Frequently asked questions

The AOS monitors temperature, humidity, light, light exposure and popularity and estimates the risk of damage to your collection as a function of the material sensitivities of the objects on display. Future data sources will include air quality, vibration, location and security.

By popularity, we mean the total time that the items have been viewed. This is measured by the presence sensor, which silently activates the smart glass and LEDs. The presence data is anonymous and GDPR-compliant, since we do not track the identity of persons. We do know however which items are the most (and least) popular in the collection (and when they are most viewed).

On the circular dashboard gauges, green represents a safe region and red represents danger. E.g. if you specify the ideal temperature range for an antique book collection as 19-21ºC, this range will appear in green; below and above that range will be red. You can then see quickly from the position of the dial if your collections are currently at risk.

By real-time, we mean that data is sampled, calculated and viewed instantaneously on the AOS Intranet. E.g. if you trigger the presence sensor by walking in front of the display, the light dial will swing upwards immediately, indicating an increased level of incident light on the items exhibited.

The material sensitivities reference the British Standards Institute (BSI) document PAS 198, entitled “Specification for managing environmental conditions for cultural collections”. This document specifies ranges of temperature, humidity and light under which each material should be displayed, based on its sensitivity (indicated as low, medium or high). The software includes examples but we recommend that you consult this reference for the full list, or simply contact us and we will be delighted to help.
