The HALO Smart Sensor can detect sounds as well.
> A leading provider, HALO Smart Sensors, sells 90% to 95% of its sensors to schools. The sensors don’t have cameras or record audio but can detect increases in noise in a school bathroom and send a text alert to school officials, said Rick Cadiz, vice president of sales and marketing for IPVideo, the maker of the HALO sensors.
> The sensors are marketed primarily for detecting vape smoke or THC but also can monitor for sounds such as gunshots or keywords indicating possible bullying.
Gunshot detection is unreliable [1]. I don't think detecting keywords is much more reliable. Actually, I speculate that detecting keywords is less reliable.
