Berg Insight estimates that connected alcohol detection and monitoring solutions reached an installed base of roughly 560,000 units across North America and Europe in 2025. The figures highlight a niche IoT market where connectivity is being driven less by consumer convenience than by compliance, supervision and safety requirements. Alcohol testing is not new, but the operational model around it is changing. For decades, many alcohol detection systems have functioned as point-in-time tools: a breath test, a vehicle interlock event, or a supervised check at a fixed location. The connected version of this market adds a different layer: remote visibility, automated reporting and the ability to respond when a test is failed, missed or potentially tampered with. That is the context for new research from Berg Insight, which estimates that the installed base of connected alcohol detection and monitoring solutions reached 374,000 units in North America and 184,000 units in Europe in 2025. By 2030, the research firm expects those figures to rise to 520,000 units in North America and close to 260,000 units in Europe. The market remains modest compared with mainstream IoT categories such as fleet telematics or smart metering, but it is notable because the connectivity requirement is tied directly to institutional workflows. Berg Insight identifies road safety and transportation, workplace safety, healthcare and rehabilitation, and legal or public safety applications as the main use environments. These are not identical markets, even when they use related sensor technologies. A compliance-driven IoT category The largest connected device segment in both regions is ignition interlock devices, which account for around half of the installed base. These systems are mainly used in Driving Under the Influence offender programmes and in workplace fleet safety applications, where a vehicle can be prevented from operating if an alcohol test is not passed.
