BuddyGuard, a Berlin-based Smart Home start-up company, has started selling its Flare home security system that uses face and voice recognition to authenticate visitors. Flare uses artificial intelligence (AI) in order to bring an additional layer of home security and will send police to a residence on its own without a user's approval. The Smart Home security system uses a software called AudioIntel that distinguishes normal noise from suspicious sounds, allowing the system to take action on its own. However homeowners will still be informed through notifications, BuddyGuard says. The saucer-like security system Flare is able to distinguish normal noise from suspicious sounds and will take actions on its own.
