Title: Building a home security system with Pi & Slack!
Duration: 10 min
Language: English
Level: Beginner
Categories:opencv, raspberry pi, slack, motion detection
Abstract
How does one make use of that raspberry pi they bought years ago? This talk will summarize how you can turn your raspberry pi into a home security system, utilizing slack as a notifications system.
Description
In this talk I will show how I turned my raspberry pi into a home security system. I will start with going over the different options for home security with a raspberry pi, then go into detail about the method I chose, which uses a video feed, OpenCV, and background subtraction to detect motion. I will then show how you can layer on out of the box image classification algorithms to reduce the number of false positives, and show how slack can be used as a notifications system and GUI to control your system. While the talk will focus on home security systems with the raspberry pi, the technologies and methods used will highlight the potential for many other use cases.
The talk outline will be something like this:
Home Security Options with the Raspberry Pi (1 minutes)
highlight different options for "home security" with a Raspberry Pi
using a motion sensor, ultrasonic sensor, and camera
The pros and cons of each solution will be discussed
Intro to OpenCV and Background Subtraction (3 minutes)
highlight how to use the Python OpenCV library to process images
talk about background substraction, and show how it can be performed with OpenCV
Using a Custom Slack App for Notifications and System Control (3 minutes)
quick overview of different options for interacting with slack: webhooks, bot users, and apps
discuss how the slack app was built with flask
show GIF demo of the app I built
Reducing False Positives with an Image Classifier (2 minutes)
show how false positives from the background subtraction method can be reduced by layering on a pre-built image classifier
emphasize the importance of combining the methods to reduce the workload on your raspberry Pi
Questions (1 minute)
End with time for the audience to ask questions.
As a student of Chemical Engineering at Queen's University, Ian was pursuing a career back home in Calgary in the Oil & Gas industry. During one summer, he was thrown into the world of data science when he started trying to make money by using Python to optimize daily fantasy sports lineups. After the oil price started crashing, he realized he should probably look for work in another industry.
With a new found passion for data science, Ian started working for Capital One in Toronto as a data scientist. For the past two years, he has been working on operational monitoring across the business, credit risk analysis, data infrastructure & risk models. In his spare time, Ian likes to participate in hackathons, work on side projects (usually involving a raspberry pi), or eat burrito boyz.
