Night Guardian / lighting and surveillance service for public

This design generates from the idea to increase pedestrian safety at night by using the existing infrastructure. The user can preorder this service on their smartphones. During the service, the drone will automatically follow the customer for lightening, navigating and video recording purpose. The video can also be used as evidence if required. 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.
