Camera

Python program to take pictures or movies triggered by motion or time on a RPi with the PiCamera attached. Code also supports the use of a PIR connected to the GPIO pins.

Prerequisites

Picamera

Install picamera and gpiozero (Python 3):

  1. sudo apt install python3-picamera python3-gpiozero -y

Be sure the Raspberry Pi camera module is connected and enabled in raspi-config:

  1. sudo raspi-config
  1. Go to 5 Interfacing Options
  2. Choose P1 Camera
  3. Choose Yes
  4. Choose Ok
  5. Choose Finish, and boot your RPi if required

PIR (optional)

Buy a PIR like the one which can be found at Kiwi.

Connect the pins of the PIR to the GPIO pins on the Raspberry Pi in the following way:

PIR GPIO
VCC 2
OUT 11
GND 14

Installation

Be sure git is installed:

  1. sudo apt install git

Now install this camera program:

  1. git clone https://github.com/Xorfor/Camera.git

This will create a Camera directory with all the software.

Update

Go to Camera folder and pull new version:

  1. cd Camera
  2. git pull

Get started

Try this program:

  1. cd Camera
  2. python3 camera.py

The output generated will look like (with logging.INFO):

Screen

Under normal conditions, if our connection drops, everything that was running inside of it is terminated. This may result in a lot of hard work being lost. The application screen allows us to create a session, which you can detach and re-attach as required. While detached, everything will continue to run as normal. If the connection drops, you can simply re-attach to the screen session and continue where you left off.

Unfortunately, Raspbian does not come with screen preinstalled, so run the following command to install it:

  1. sudo apt install screen

Once installed, it can be launched by running the following command:

  1. screen

You will receive a welcome screen. Now you can enter your command, eg:

  1. python3 camera.py

Once detached, you can return back to the screen session by running the following command:

  1. screen -x
