Intelligent Threat Detection — Beyond the Camera

About HALO Smart Sensor
HALO Smart Sensor is a multi-threat IoT detection device that addresses behavioral and environmental threats that cameras cannot detect. Originally designed to detect vaping in school restrooms, one of the most common disciplinary challenges nationwide. HALO has evolved into a sophisticated multi-sensor platform that simultaneously monitors for vaping, THC, chemical threats, noise anomalies, and even specific keywords.
The HALO sensor's gunshot detection capability is particularly significant for schools, hospitals, and public venues. The sensor analyzes acoustic signatures and, combined with its keyword detection, can alert administrators and security personnel to potential threats in spaces where cameras cannot be placed due to privacy regulations.
Integration with leading VMS, access control, and mass notification platforms allows HALO detections to trigger automated response workflows — locking doors, alerting staff, and notifying law enforcement all within seconds of a detected threat.
