From rising temperatures to the growing challenge of vaping, today’s schools face increasing pressures that impact safety. According to Dominic Komarek, Product Manager at Verkada, the next generation of AI-powered sensors is giving school leaders the visibility they need to act early and protect students.
From heat and air quality to vaping and bullying, today’s schools face a growing list of environmental and behavioural challenges that can impact student safety, well-being and learning outcomes. AI-powered sensors are giving administrators the visibility they need to address these risks proactively and create safer, healthier and more resilient learning environments.
The expanding challenge of school safety and comfort
Running a school today means more than managing teachers and class timetables. School leaders are also responsible for maintaining safe, comfortable environments that support concentration and learning. But rising temperatures, ageing infrastructure and new behavioural issues such as vaping have made that mission increasingly complex, particularly across large campuses with limited staff.
Many schools still rely on disconnected systems such as traditional CCTV or HVAC platforms to monitor and respond to issues. These legacy tools often operate in isolation, requiring manual oversight and offering only fragmented views of what is happening across a campus. Without a unified perspective, administrators are left reacting to problems rather than preventing them.
AI-powered environmental and security sensors are transforming how schools detect, understand and respond to emerging risks. By combining real-time environmental data (such as temperature, air quality and noise) with behavioural insights (such as vaping activity), these sensors give school leaders a connected view of their facilities, all while protecting student privacy. This unified visibility helps administrators spot trends, automate alerts and act quickly before minor issues escalate. Whether it is detecting a sudden temperature spike, poor ventilation or unusual noise levels, AI sensors help schools proactively care for students, teachers and staff.
Monitoring temperature, humidity and air quality
Comfortable classrooms directly affect student performance. Research published in PLOS Climate found that excessive heat reduces cognitive ability, while another study of children in the US, England, Sweden and Denmark revealed that student performance increases by an average of 20% when classroom temperatures drop from 30°C to 20°C.
AI-powered sensors continuously track key metrics such as temperature, humidity and the Air Quality Index (AQI), flagging problems such as poor ventilation, high particulate levels or failing HVAC systems. These insights allow schools to identify costly building issues like mould or structural degradation and take targeted action to maintain healthy learning conditions.
By integrating with other systems such as cameras, these sensors provide a comprehensive view of environmental conditions, helping administrators identify root causes more quickly and maintain comfortable, compliant classrooms year-round.
Detecting and addressing vaping behaviours
Vaping has become one of the most pressing health and disciplinary challenges in schools. Beyond health risks, discarded vapes can damage plumbing and create maintenance headaches.
AI environmental sensors can detect vape emissions, cigarette smoke and even cannabis use, sending immediate alerts to administrators. These insights help staff intervene quickly and compassionately, supporting individual students while also identifying broader trends that inform prevention programmes.
“The purpose of the sensors is to start the conversation around smoking with students who may be experimenting, so they understand the impact it has on their well-being – both physical and mental.
“We now have a camera that overlooks the main corridor outside the bathrooms, so when vape smoke is detected, we have immediate video context into the situation,” said John Langrill, Director of IT and Campus Management at Chartwell School.
Monitoring noise to support privacy and safety
Noise levels can be a key indicator of student well-being. Persistent high-volume environments may signal distress, conflict or bullying – especially in areas where cameras are not appropriate, such as bathrooms or locker rooms.
AI-powered sensors that monitor decibel levels – not conversations – allow schools to detect sudden spikes in noise without recording audio or violating privacy. When an anomaly occurs, administrators receive instant alerts and can cross-reference contextual video to understand what is happening and respond appropriately.
The bigger picture – building resilient, data-informed schools
AI-powered sensors form the foundation of a proactive, data-driven approach to student safety and well-being. By unifying environmental, behavioural and operational data, schools can make smarter, faster decisions that improve comfort, focus and overall performance. As temperatures rise and safety concerns evolve, AI-driven visibility offers a clear path forward. Schools that embrace these technologies today are building not only safer campuses, but also improved learning conditions for the future.
