Overview
The Halo 4 Smart Sensor is a ceiling-mounted multi‑sensor device that detects vape events, monitors temperature and air quality/contaminants, and performs advanced audio analytics for safety events. It delivers real-time alerts and integrates with video and management systems while preserving privacy.

Key capabilities

• All-in-one sensing: vape detection (THC/related events), temperature monitoring and air quality/contaminant detection
• Advanced audio analytics: classification of sounds such as screams and gunshots
• Occupancy monitoring: supports Amplify wireless occupancy sensor functionality on compatible Halo 4 occupancy models
• Integration-ready: interoperable with Avigilon Unity (on‑prem) and Avigilon Alta (cloud-native)
• Open standards: supports ONVIF Profile M and Profile T for interoperability

Operational notes

• Amplify wireless occupancy features require compatible Halo 4 firmware (example minimum reported: 5.42.1.32 or later)
• Certain occupancy features are available only on specific Amplify/occupancy-enabled Halo 4 models
• Product availability noted for U.S. and Canada; check local availability

Use cases

• Rapid vape detection and environmental contaminant alerts for schools, corporate, and institutional facilities
• Occupancy and space-usage monitoring to support facilities and energy management
• Audio-based safety alerts (scream/gunshot detection) to accelerate incident response
• Integration with video management and access control systems for unified situational awareness
