Amazon Ring working on doorbells that detect people by their skin and smell

Amazon's Ring cameras may be able to detect people by their smell, according to new patents the company submitted. Ring's internet-connected doorbells would also be able to scan neighbourhoods and identify "suspicious" people based on their skin texture, gait (walk) and voices. The cameras do not have facial recognition, but the company has 17 patents for features that use the technology. One patent, Insider reports, mentions a "Neighborhood Alert Mode" that would send an alert to other neighbours after a user share a picture or video of someone found suspicious that prompts other doorbells to start recording – even if the person does not come up to their doorbell. The biometric information mentioned includes palm, finger, retina, iris, skin texture, typing, gait, voice, and "odour recognition".
