Description

The HALO Smart Sensor 3C-PC is the most advanced privacy-focused environmental and security sensor available. Designed for spaces where cameras and microphones cannot be used, HALO 3C-PC combines health, safety, and security monitoring in one compact device. It detects vaping (including THC), smoke, hazardous gases (CO₂, CO, NO₂, VOCs, particulates), and changes in air quality, temperature, and humidity. For safety and security, it features gunshot detection, aggression and keyword alerting, motion and tamper detection, plus an onboard speaker and multi-color LED indicator.

The 3C-PC model adds privacy-safe people counting technology (heat-based, not cameras), capable of detecting up to 9 occupants in a monitored zone — making it ideal for restrooms, classrooms, hotels, and other sensitive areas. With Power-over-Ethernet (PoE) and vandal-resistant housing, the HALO Smart Sensor 3C-PC installs easily and integrates seamlessly with existing VMS and building systems. Optional HALO Cloud services unlock live dashboards, real-time alerts, trend reports, and heat maps, providing full situational awareness and compliance reporting.

This is the next generation of smart building intelligence — protecting health, safety, and security while preserving occupant privacy.
