Various examples to record video on Raspberry Pi using the Raspberry Pi camera and a button or PIR sensor to trigger recording.

Written in Java.

git clone https://github.com/joe-akeem/raspi-cam.git

cd raspi-cam mvn install

mkdir /home/pi/capture

only needed if a remote debugger shall be connected: export MAVEN_OPTS="-Xnoagent -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=6006"

1. Start the camera by pushing the button, stop it by releasing the button -> the button must be connected to GPIO02 (27)

sudo mvn -PbuttonCam install exec:java

2. Play a sound when the PIR notices movement -> the button must be connected to GPIO02 (27)

sudo mvn -PwelcomeSound install exec:java

Videos end up in /home/pi/capture

E.g. on Ubuntu: sudo apt-get install gpac MP4Box -add filename.h264 filename.mp4
