OpenCV and the Wild Kingdom
The author used a thermal camera and OpenCV for motion detection, initially aiming at the sky but later focusing on security. Python's speed issues led to transitioning to C++. Identified culprits stealing cat food prompted adjustments for security.

The article discusses the author's project involving the use of a thermal camera and motion detection using OpenCV to monitor activity in his surroundings. The author initially experimented with pointing the camera at the sky but later focused on detecting motion for security purposes. The process involved recording frames with motion, timestamping imagery, and potentially recording a live feed. The author encountered issues with Python's speed and eventually transitioned the project to C++. The motion detection tool was used to uncover the mystery of food disappearing from a cat feeder in the author's carport. Through the surveillance footage, the author identified various culprits, including bugs, neighborhood cats, and possibly a raccoon or opossum. As a solution, the author adjusted the cat's feeding routine to prevent further theft and considered implementing an NFC-enabled cat door for added security. The project showcases the practical application of computer vision technology in real-world scenarios.

7 commentsI would love for this thing to consume minimal power too, so I only have to recharge the battery once per week (for example, this might not be possible, or maybe something much better is possible, i have no idea)
The most convenient option I can think of is a cheap smartphone with 3g/4g data connection that can somehow integrate with the motion sensor and enables me to write some code to send a message.
There must be something better suited to this though. Thoughts welcome.

I wonder how difficult it would be to detect specific actions in the video frames, like “cat eating food”?
