The Avigilon HALO 4 Smart Sensor enhances existing video security systems by providing environmental insights, even in areas where cameras aren't appropriate. This intelligent, all-in-one device can detect vape, monitor air quality, and send alerts for safety events and more. It seamlessly integrates with Avigilon Unity Video and Alta Video software for increased situational awareness. The built-in speaker can play pre-recorded audio messages to discourage security and safety events and enforce policies such as “no smoking” in specific areas.
