A Node-RED node to take photos on a Raspberry Pi. This node will only work on an Raspberry Pi with a Raspberry Pi Camera enabled.
Run the following command in the root directory of your Node-RED install or home directory (usually ~/.node-red) and will also install needed libraries.
npm install node-red-contrib-camerapi
Additionally you have to install on the Raspberry Pi
First you have to install a Raspberry Pi Camera physically and don't forget to enable the Camera in raspi-config. See Pi Camera setup. Also check if you have installed the picamera module for python.
sudo apt-get updatesudo apt-get install python-picamera python3-picamera
If you are using the default path during the fileoption set - the path /home/pi/Pictures will be used.
This node is tested on RASPBIAN, Nodejs V6.x LTS and NPM 3.x on Node-Red 0.18.
This node is to take a photo in a given format directly from the Raspberry Pi Camera. Using the Filemode the image of the photo is stored into the file-system and msg.payload will give you the path and the filename including extension to the photo. In Buffermode the image will reside as a buffer in msg.payload. For the possible parameters see documentation under picamera parameter settings.
