Motion Detection

Build your own low cost security cam!

This is the backend, which is based on the python raspberry pi camera module interface picamera, for the coming soon iOS-App.

Please feel free to change and improve the code, this is my first python project.

Features

• records in 1080p with low cpu usage
• records also a few seconds before the motion was detected
• creates a thumbnail of the event as preview for the video
• define areas which don't need to checked (e.g. a tree in the wind)
• optional nightmode with lower fps but much brighter videos
• live view

Requirements

• Raspberry Pi
• Camera Module

Installation

Instructions for an installation on Raspbian Jessie Lite

• Install dependencies

sudo apt-get install python-imaging gpac libav-tools imagemagick git python-dev python-pip
sudo pip install pyephem numpy picamera

• Clone this repository

sudo git clone https://github.com/dneunkirch/motiondetection.git /etc/motiondetection

• Create a symlink for the init script

sudo ln -s /etc/motiondetection/scripts/startup.sh /etc/init.d/motiondetection

• Register the init script

sudo update-rc.d motiondetection defaults

Now you're able to start/stop the motion detection with the command sudo service motiondetection {start|stop}. The motion detection starts also automatically at startup.

• Configuration-File

/etc/motiondetection/python/config.ini

---

URLs

The port (default: 8080) and credentials (default: username, password) can be changed in the config file. You're able to add multiple users in the users section or even turn the basic authorization off.

• Live MJPEG stream /live or /live.mjpeg

• Current live picture /live.jpg

• Exclude areas from motion detection /blacklist.html

• Delete an event /delete?file=filename_of_video.mp4

  A GET request to this endpoint deletes the given video including his preview image.

• Captured Videos /events

  Returns an array of all captured videos as following object:

  {
    "date": "yyyy-MM-dd_HH-mm-ss",    // date of video
    "video": "/events/video.mp4",     // path to video
    "poster": "/events/preview.jpg",  // path to preview image
    "size": 1000000,                  // size of video in bytes
    "duration": 10                    // duration of video in seconds
  }

For testing and debugging

• Fake Motion /force_motion

• Stop Faking Motion /stop_force_motion

• Activate Daymode /daymode

• Activate Nightmode /nightmode

  Works only if night_mode_allowed in the config is True
