1. Preparation
1. Raspberry Pi 4B
2. Raspberry Pi camera 500W pixels (Taobao more than ten dollars)
3.motion
2. Operation steps
1. Enter the settings to open the camera module
In the Raspberry Pi terminal window type:
sudo raspi-config
Select interface option–>I1 Camera in turn, then enter, confirm, and restart, as shown in the figure
2. Take pictures
sudo raspistill -t 1000 -o first.jpg
-t 1000 # means to take pictures after a delay of 1000ms.
-o first.jpg #Represents the jpg format file named first.
Use the ls command to see if you have successfully captured and saved the file.
For raspistill detailed instructions, please refer to this article
to view the photos you just took: xdg-open image path.
xdg-open first.jpg
3. Video
raspivid -t 5000 -o 1.h264
-t 5000 #Indicates recording 5000ms video.
-o 1.h264 #Indicates the h264 format file named 1.
View the video you just recorded: xdg-open video path.
xdg-open 1.h264
4. Real-time monitoring
(1) Install the motion module
sudo apt-get install motion
(2) Configure motion
command line input:
sudo nano /etc/default/motion
Change the no inside to yes
start_motion_daemon=yes
**Note:** If there is nothing after opening the file, you start_motion_daemon=yes can add it yourself
(3) Configure the motion.conf
command line input:
sudo nano /etc/motion/motion.conf
**Note:** Be sure to stream_maxrate 参数改为100add it yourself if you don’t have it.
Ctrl+s to save, Ctrl+x to exit
(5) Start and view
Kill the motion first.
sudo killall -TERM motion
Then start motion.
sudo motion
Now you can go to the browser to view the real-time monitoring, and enter in the browser:
**Note: **The following IP is replaced with your own Raspberry Pi IP address, for example, mine is 192.168.137.79, and then it ishttp://raspberry 192.168.137.79:8081
http://raspberry IP:8081
3. Summary
I just started to get in touch with Raspberry Pi, and I plan to use Raspberry Pi to do some small projects I like, and use this blog series as my own study notes to communicate and learn with everyone. The May 1st holiday is over, and I wish everyone a happy May 4th Youth Day! I would like to share the passion of youth with all of you.
