Problem
Surveillance of large properties, such as farms, can only be done physically or through the use of expensive camera systems.
![Page 6: Property Surveillance UAV System Mid Semester Presentation Senior Design I October 10, 2013 [1]](https://reader035.vdocuments.mx/reader035/viewer/2022062311/5a4d1ae77f8b9ab059979886/html5/thumbnails/6.jpg)
Solution
An autonomous property surveillance system that consists of a quadcopter outfitted with a camera
for video surveillance purposes.
The Watchdog UAV

Technical ConstraintsName Description
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
Name Description
Safety and Health The Watchdog UAV may turn into a dangerous projectile if it were to malfunction mid-flight; precautions for this must be taken.
Ethical The system is strictly for the use of private property surveillance and must operate under any Federal Aviation Administration legal guidelines.
![Page 10: Property Surveillance UAV System Mid Semester Presentation Senior Design I October 10, 2013 [1]](https://reader035.vdocuments.mx/reader035/viewer/2022062311/5a4d1ae77f8b9ab059979886/html5/thumbnails/10.jpg)
Safety and Health
• Lethal projectile• Excessive altitudes– 61 meters operational height limit
• Fail-safe mechanisms• Disposal of lithium ion battery
![Page 11: Property Surveillance UAV System Mid Semester Presentation Senior Design I October 10, 2013 [1]](https://reader035.vdocuments.mx/reader035/viewer/2022062311/5a4d1ae77f8b9ab059979886/html5/thumbnails/11.jpg)
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
