The MIPI connector for the Raspberry Pi cam is placed in the middle of the board closed to the CM3 socket as shown below:
We have chosen this position to place the camera on the front panel of the DIN rail case.
Insert the camera connector with the blue band oriented to the relay then turn-on the board and access to the Linux prompt using an ssh connection.
Select Interfacing Options-->P1 Camera and enable the camera interface.
Install this overlay (dt-blob.bin) on the microSD by typing:
sudo wget http://goo.gl/U4t12b -O /boot/dt-blob.bin
Then check if the camera is enabled by typing:
I found on this URL https://blog.miguelgrinberg.com/post/flask-video-streaming-revisited a very easy way to implement example of video streaming made in pure Python written by Miguel Grinberg.
I suggest to read this tutorial to understand how it works. But if you want to try quickly these are thet steps to do:
Install Flask, the Python support for the Pi Camera and git:
sudo apt update sudo apt install -y python-flask python-picamera git
Clone the flask-video-streaming repository:
git clone https://github.com/miguelgrinberg/flask-video-streaming.git
Move inside the directory created by Git:
CAMERA=pi python app.py
Open a browser on your PC and go to the URL:
Create a filed called /lib/systemd/system/flask.service with the follow content:
[Unit] Description=Flask After=systemd-user-sessions.service [Service] Environment="CAMERA=pi" ExecStart=python flask-video-streaming/app.py Restart=on-abort User=pi WorkingDirectory=/home/pi [Install] WantedBy=multi-user.target
Enable the new service:
sudo systemctl daemon-reload sudo systemctl enable flask.service sudo systemctl start flask.service
