I bought a IP camera (TP-Link Tapo C200) and I would like to get notification when it detect any motion.
But it did not support automation, I only can keep my eyes on Tapo app to aware the motion change.
Therefore, I make a function to do that.
This function include 2 handler
This file will grab single frame from RTSP stream.
It use FFmpeg to do
This file will receive 2 images and detect the difference.
It use OpenCV to do
Download opencv.js file (I used version 4.5.2) and put it to this folder
Run npm install
Provide the base.jpg to this folder, It will be treated as the first image, the second image will be compared to the first and find the difference
Just enter the following command
npm start -- --url "<your_url>"
You also can create .env file, put URL variable to there and run npm start.
In the case you're using C200 camera, the URL should be rtsp://<usr>:<pwd>@<ip>:554/stream1.
For example, create a js file (i.e app.js) at parent folder
Put this script to file and adjust URL, motion-detect-js folder path
const fs = require('fs')
const smartCam = require('./motion-detect-js')
const image = fs.readFileSync('./base.jpg')
smartCam(image, 'rtsp://usr:[email protected]/stream1').then(() => {
console.log('SUCCESS !!!')
}).catch((err) => {
console.log(err)
console.log('ERROR !!!')
})Put a image file to folder (base.jpg)
Open terminal at your js file path (app.js)
Exec node app.js and look output
I'm going to import this function to Node-RED.
