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

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

System Overview

Design Constraints

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).

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.

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

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
