Night Guardian

This design generates from the idea to increase pedestrian safety at night in the form of sharing economy. The user can pre-order this service on their smartphones. During the service, the drone will automatically follow the customer for lightening, navigating and video recording purpose to deter potential crime. When emergency happens it can report to police immediately . When out of the service, the drone is attached to the street lamp and can be treated as a surveillance camera. We believe this service can deter the potential crime at night with the minimum social resources cost.
