For a full description see this post http://raspberrypimaker.com/simple-security-camera/

• Some type camera. Webcams, IP cameras and the RaspberryPi camera is supported

Installing ffmpeg

Installing fswebcam

Please see this webpage

Installing raspistill

raspistill should be included with the camera software. See this page for more information

Installing drpbox-uploader

If you would like the scripts to automatically upload images and/or videos to DropBox you will need the dropbox-uploader.sh script. Download the script with this command curl "https://raw.githubusercontent.com/andreafabrizi/Dropbox-Uploader/master/dropbox_uploader.sh" -o dropbox_uploader.sh And then chmod +x dropbox_uploader.sh Run the script once to setup the access key. For more information see this web page NOTE: The dropbox_uploader.sh needs to be in the same directory as the other scripts in this package. It will not work if you put it in a central place and add it to the path. Sorry.

Installation

1. Create a dedicated folder for your images and videos
2. Clone the git repository or download and unzip
3. Change the scripts to have the execute attribute chmod +x *.sh
4. Thats it!

Use

It is required that each camera have a dedicated directory folder to store the images. Also, please a copy of all scripts (including dropbox-uploader.sh) into each folder. gsnap.sh will snap an image from a camera. The image is saved in the current directory. movie.sh will take a collection of timestamped images and convert them to a video file. crontab-edit.sh adds lines to the crontab scheduling image snaps, movie creation and Dropbox uploads gsnap-cleanup.sh adds lines to the crontab to cleanup (delete) old images and movies
