Camera & Surveillance¶

The web interface is accessible via:

• URL = http://<your.IP>/rpicam

To access you recordings remotely without the web interface, you might want to have one of DietPi’s file servers installed.
Directories used by RPi Cam Web Interface:

• Media directory = /mnt/dietpi_userdata/rpicam
• Accessed from file server = /rpicam

RPi Cam Web Interface can be updated to the latest version by reinstalling it via

dietpi-software reinstall 59

The RPi camera module is automatically enabled during the installation process. However, It requires a reboot and/or sometimes a power cycle to take effect.
The camera activation may be checked via dietpi-config > Display Options > RPi Camera to show [On]. Additionally, the behaviour of the cameras LED can be set in the same dialog via RPi Camera LED.

Remark: After changing the camera activation you need to reboot and/or sometimes power cycle the SBC incl. camera.

The web interface is accessible via port 8765:

• URL = http://<your.IP>:8765
• User = admin
• Password = not required

Passwords can be configured in the web interface.

To access you recordings remotely without the web interface, you might want to have one of DietPi’s file servers installed.
Directories used by motionEye:

• Media directory = /mnt/dietpi_userdata/motioneye
• Accessed from file server = /motioneye

motionEye can be updated to the latest version via

sudo pip3 install -U --pre motioneye

If you have an official Raspberry Pi camera module, it can be enabled via dietpi-config > Display Options > RPi Camera to show [On].
Additionally, the behaviour of the cameras LED can be set in the same dialog via RPi Camera LED.

Remark: After changing the camera activation you need to reboot and/or sometimes power cycle the SBC incl. camera.

The web interface uses port 8082:

• Stream: http://<your.IP>:8082/?action=stream
• Snapshot: http://<your.IP>:8082/?action=snapshot
• HTTP plugin docs: https://github.com/jacksonliam/mjpg-streamer/blob/master/mjpg-streamer-experimental/plugins/output_http/README.md

When OctoPrint is installed, it will be automatically configured to use the mjpg-streamer HTTP stream and snapshots, as this is the major use case this software title was requested for. You can review and test the setup from within the OctoPrint web interface settings.

By default, the HTTP stream is accessible on port 8082 without any authentication. This is required when you embed it into OctoPrint, since the browser sends the request and cannot pass credentials currently. If you however use the stream otherwise, especially when you expose it to the world-wide-web, we recommend to setup a password. For this:

1. Run dietpi-services
2. Select mjpg-streamer
3. Select Edit to open a service override config with the nano command line editor.
4. In the [Service] section, uncomment the ExecStart= line and add -c username:password to the last single quote ' block, with username and password of your choice.

5. Above that line you need to add another ExecStart= without any content, which is to remove the original start command, so that yours is effectively replacing it. The file may finally look like this:

   [Unit]
   #Description=mjpg-streamer (DietPi)
   #Documentation=https://github.com/jacksonliam/mjpg-streamer/tree/master/mjpg-streamer-experimental
   #Wants=network-online.target
   #After=network-online.target dietpi-boot.service
   
   [Service]
   #User=mjpg-streamer
   #WorkingDirectory=/opt/mjpg-streamer
   ExecStart=
   ExecStart=/opt/mjpg-streamer/mjpg_streamer -i 'input_uvc.so -d /dev/video0' -o 'output_http.so -p 8082 -n -c micha:youNeverGuessThis!'
   
   # Hardening

   #PrivateTmp=true
   #ProtectHome=true
   #ProtectKernelTunables=true
   #ProtectControlGroups=true
   
   [Install]
   #WantedBy=multi-user.target
   

6. Press Ctrl+O to save the file and Ctrl+X to exit the editor. When exiting dietpi-services, the service is automatically reloaded to be password-protected from now on.

mjpg-streamer can be updated to the latest version by reinstalling it via

dietpi-software reinstall 137

You can view the service logs via

journalctl -u mjpg-streamer

and the service status via

systemctl status mjpg-streamer

If you have an official Raspberry Pi camera module, it can be enabled via dietpi-config > Display Options > RPi Camera to show [On].
Additionally, the behaviour of the cameras LED can be set in the same dialog via RPi Camera LED.

Remark: After changing the camera activation you need to reboot and/or sometimes power cycle the SBC incl. camera.
