Bear Grid is developing a portable system of sound, tone, and noise classification coupled with software designed to find and inform about possible security hazards on large-perimeter estates such as farms, backyards, plant areas, etc. The solution is capable of decoding noises and environmental sounds, classifying threats and learning their types, learning and customizing within the first week of usage, showing threats as alerts and notifications, and localizing the source of the sound. The system is completely concealed and hidden and could be integrated with a variety of smart solutions including smart homes, smart cities, and other sensors.
