Drone Technology

One of the most attractive (or most likely to be approved by regulation) application of drone, is photographing.
The attractiveness lies in,

1. Unique perspective of viewpoint. No or very little alternative.
2. Technical feasible. The only thing need to carry is camera or lens; requirement for speed is low; requirement long time in air is flexible.
3. public safety is most likely to be met

However the major concern is privacy of citizens and secrecy of national service.

Then two techniques are needed to clear the concern or protect the privacy and secrecy.

1. Drone detection
• Through sound
• Through vision
• Through infrared radiation
2. Drone communication blocking
• Jamming communication
• Disable lens
