Capture Comprehensive Health & Safety Awareness For Your Building With HALO Smart Sensor

“The Halo detection system is serving its purpose as a deterrent to our students to discourage vaping. Prior to their installation we had over 20 EMS calls for students that we believed were suffering from effects of vaping. Since the devices have been in place, we haven't had to make any.”
Associate Principal and 504 Coordinator, North Scott High School, Eldridge, IA

HALO Smart Sensor and its air-quality sensor array is a key component in the solution to providing a low-risk environment in public and even private settings, by monitoring Carbon Dioxide (CO2), Particulate concentrations, Humidity, Volatile Organic Compounds (VOC), Nitrogen Dioxide (NO2), tobacco smoke, and vape and THC vapor in the air. This multi-sensor is capable of vape detection, smoke detection, THC detection, and sound abnormalities like gunshots and shouting in areas where a camera cannot be placed. HALO delivers safe, healthy, and comfortable environments that keep all personnel safe while saving money by efficiently running the HVAC system.

How HALO Smart Sensor Is Helping The World Around Us

Protecting Public Restrooms

Public restrooms pose a unique security and health challenge in that there is an expectation of privacy within the restrooms, therefore security cameras and recording are not permitted. This often leads to public restrooms being used for substance abuse, unpermitted vaping, violence, loitering, and more unsafe or unpermitted activities. The HALO Smart Sensor is designed to help all facilities keep their buildings and bathrooms safe through Health, Safety, and Vaping detection. The HALO vape detector can detect vaping, vape with THC, aggression, motion, occupancy, and more, all while protecting the privacy of individuals in the restroom by not using audio or visual recording.

Stopping Drug Use

The HALO Smart Sensor has been used for years in privacy areas to detect and alert to Vaping, Smoking, and Vaping with THC. Many drugs, such as marijuana, methamphetamines, ketamine, and others emit a vapor that can deposit on surfaces, leaving residues similar to smoking indoors, according to a technical paper produced by the government of West Australia. Today libraries, retail outlets, and public agencies are using HALO vape detectors to help identify and alert to possible drug use early on. HALO provides instant alerts to vaping and smoking, which also covers THC vape and marijuana smoke as illicit drug usage. By providing these instant alerts, security/facility management can immediately address the culprits prior to potential overdoses and serious contamination issues occurring on the premises.

Helping People Breathe Better

The air we breathe inside a building is just as important as the air we breathe when outside. Just as the outside air can get contaminated and become hazardous to our lungs, the same applies to the air we breathe inside. With HALO’s air quality sensors, facility managers can see the average quality of the air being consumed inside your building. As part of its AQI measurements, HALO monitors CO2, VOC, NO2, and particulate concentrations in the air. By monitoring various particulate sizes, HALO can track their levels, and when unsafe levels are reached, HALO alerts building management personnel. Occupants of the building can open windows to bring in the fresh air, or HALO can notify the BACnet interface-equipped HVAC system to open its dampers to allow fresh air inside – automatically.

Providing Personal Security

HALO Smart Sensor is disrupting the world of physical security – in a good way! HALO has become the industry leader in monitoring facility privacy areas, as it does not use cameras, record audio, or capture any personally identifiable information to sense a multitude of readings – including gunshot detection, aggression detection, vaping, and more. HALO delivers comprehensive safety and security awareness by means of its array of sensors that detect aggression, gunshots, motion, occupancy, and keyword alerts.
