Given the actual technology, the short autonomy of typical quad copters( around 30 minutes)— makes almost impossible to maintain a fleet of drones 24 hours a day surveilling the city. Therefore, only activating the drones when needed would make the things much easier, and would be a more realistic approach to solve the problem.
Our system is based on an actual service from the Red Cross. The system would consist of a button, given to the homeless people. When activating the button, two protocols would be immediately activated:
- Make an automatic emergency call to the police services.
- Activate the closest drone to the location to film whatever is happening at the location of the user.
Given that the calling service from the button is already being used by the Red Cross, it would only be needed to add a GPS to track the location from the user.
