Prevent Vaping While Capturing Comprehensive Health & Safety Awareness for your Building

HALO is the essential component in the solution to providing a low-risk, healthier environment by monitoring Carbon Dioxide (CO2), Particulate concentrations, Humidity, Volatile Organic Compounds (VOC), and Nitrogen Dioxide (NO2) in the air. This multi-sensor provides vape detection, smoke detection, THC detection, and sound detection of abnormalities like gunshots and shouting in areas where a camera cannot be placed. HALO delivers safe, healthy, and comfortable environments that keep all occupants safe while saving money by efficiently also running the HVAC system.
