Gain Deeper Insight with HALO Cloud
For organizations already using HALO sensors like the 2C, 3C, and 3C-PC, the HALO Cloud application is a game-changer. It transforms raw data from your devices into a centralized, actionable intelligence hub. This cloud-based platform empowers your teams to manage multiple devices across various sites, providing a comprehensive overview of safety, security, and air quality to improve operational efficiency.
HALO Cloud is designed to help your staff respond more quickly and effectively to incidents. It moves beyond simple alerts to offer a suite of powerful management and analytics tools.
Key Features of HALO Cloud
- Centralized Dashboard: Get an at-a-glance view of your entire sensor network. The dashboard displays the most recent events, current sensor readings, event hotspots, and overall system health, enabling you to assess potential issues quickly.
- Real-Time Notifications: Configure custom alerts sent directly to your team via email or mobile app push notifications. You can tailor these alerts by event type, specific devices, and recipient lists, ensuring the right people are notified instantly.
- Advanced Analytics and Reporting: Dive deep into trends with custom graphs and heat maps. Analyze event data to identify when and where incidents occur most frequently, enabling you to allocate resources more effectively. You can also download up to three months of data to satisfy reporting requirements for regulatory bodies.
- Interactive Live View Map: When an event is detected, see its exact location on an easy-to-use interactive map. This visual context accelerates incident response by showing security personnel precisely where they are needed.
Operational Outcomes
- Faster response times via automated alerts.
- Centralized monitoring reduces manual checks.
- Compliance reporting simplifies audits.
By leveraging HALO Cloud, organizations can transition from a reactive to a proactive security posture, utilizing data to refine safety measures and validate their effectiveness.

Quick Recap: The Avigilon HALO ecosystem includes smart environmental and behavioral sensors that detect events like vaping, aggression, and poor air quality while maintaining total privacy in camera-restricted areas.
Seamless Integration with Avigilon Unity Video
The power of HALO sensors is magnified when integrated with Avigilon Unity Video, a leading AI-powered video management software (VMS). This seamless connection creates a comprehensive security solution that bridges the gap between areas with and without video surveillance.
When a HALO sensor detects an anomaly – such as a gunshot, a call for help, or vaping – it can trigger an immediate and automated response within Unity Video. An alert is sent directly to the VMS, which can automatically pull up a live feed from the nearest camera. This allows security operators to gain immediate situational awareness of the area surrounding the privacy-sensitive space, confirming the threat and dispatching a response without delay.
This integration is invaluable in scenarios like a school restroom. If a HALO sensor detects vaping, it can simultaneously flash its built-in LED lights as a deterrent, send a notification to a school administrator’s mobile device, and bring up video from a camera in the adjacent hallway. This ensures incidents that may have otherwise gone unnoticed are addressed swiftly.
Quick Recap: Unity Video integration links HALO alerts to nearby camera feeds, enabling instant verification of incidents in areas sensitive to privacy.

Coming Soon: The Unity HALO 4 Smart Sensor
Avigilon is pushing the boundaries of discrete security even further with the upcoming Unity HALO 4 Smart Sensor. This next-generation device is engineered to provide smarter insights in any environment, offering a multi-sensor solution for real-time alerts while completely preserving privacy.
