4. Problem Surveillance of large properties, such as farms, can only be done physically or through the use of expensive camera systems.

5. Solution An autonomous property surveillance system that consists of a quadcopter outfitted with a camera for video surveillance purposes.

6. System Overview UAV Base Station

7. Design Constraints

8. Technical Constraints NameDescription Transmission Distance The UAV’s transmitter/receiver must be able to transmit/receive within at least a 700 m unobstructed view. Operating Height The UAV must operate under 61 m depending on obstacles present on the property (e.g. power lines, trees, buildings). Persistence The quadcopter’s battery must have a life span of around 15 min. per flight and must operate at a speed of at least 4.5 m/s. Lift/Weight Ratio The UAV must be able to produce 6 kgs. of lift, providing a 2:1 lift ratio. Video Resolution The video transmitter must provide a video resolution of at least 640x480 pixels (standard resolution).

9. Practical Constraints NameDescription Safety and HealthThe Watchdog UAV may turn into a dangerous projectile if it were to malfunction mid-flight; precautions for this must be taken. EthicalThe system is strictly for the use of private property surveillance and must operate under any Federal Aviation Administration legal guidelines.

10. Safety And Health Lethal projectile Excessive altitudes 61 meters operational height limit Fail-safe mechanisms Disposal of lithium ion battery

11. Ethical Private property surveillance ONLY! Federal Communications Commission (FCC) guidelines Federal Aviation Administration (FAA) guidelines 122 meters max No operation near airports IEEE Code of Ethics must be followed

12. Charging Station Testing

13. Charging Station Due to the complexity and the dangers of charging lithium-ion polymer batteries, smaller charger will be created as a proof of concept. Video transmitter battery Dual-cell 7.4V lithium-ion polymer Microchip MCP73842 – Charges single or dual cell
