[Raspberry Pi 4B Review] Raspberry Pi 4 connected to USB camera to achieve network video monitoring [Copy link]

 

The Raspberry Pi 4 itself has a USB interface and a Gigabit network port, and the CPU is also very fast. You can use the Raspberry Pi to connect a USB camera for network video monitoring. You can check on children or the elderly at home, or use it to check fish tanks, parking spaces, etc.

1. Use the lsusb command to check whether the system supports

The Raspberry Pi uses the official system. The USB camera I found is a generic camera from decades ago. Using the lsusb command, I found that the system still supports this camera.

2. Check for details

Use the command to view video0

ls /dev

3. Check the USB camera parameters

Use the command (v4l2 is the letter l) v4l2-ctl -d /dev/video0 --all

You can see that my camera has a resolution of 640*480

4. Install motion

Install using command line

sudo apt-get install motion

5. Modify the configuration file

sudo nano /etc/motion/motion.conf

Change to

width 640

width 480

webcontrol_localhost off

stream_localhost off

6. Run motion

Enter the command sudo motion to start running, and press Ctrl+C to exit.

7. LAN web view

Enter the address of the Raspberry Pi on the PC . The viewing port for a single camera is 8081 , and the port for multiple cameras or configuration is 8080.

8. External network (wide area network) web view

You need a public IP , set up DDNS , and set up the router. There are two ways to set it up: one is to set the IP address of the Raspberry Pi to the DMZ host, and the other is to map the IP address of the Raspberry Pi to a port. I won't go into detail here.
