Thousands of network cameras are connected to the Internet and provide real-time visual data (image or video). Many network cameras require no password and anyone connected to the Internet can retrieve the data,i.e., the data is publicly available. This program considers only publicly available camera data.

Even though the data is publicly available to anyone interested seeing, there are several problems. First, there is no central repository where network cameras must register. Thus, significant efforts must be taken to find various sources of data. Second, different brands of network cameras need different methods to retrieve the data. The cameas may also provide different data formats: some provide individual JPEG images; some provide motion JPEG (MJPEG) video; some others provide H.264 video.

Many organizations (such as departments of transportation) aggregate streams of multiple cameras and put these streams on web sites. However, these web sites have different formats and styles. Some web sites use simple HTML; some use CSS; some use Javascript. Some web sites have fixed URLs for different cameras. Some web site have dynamically generated URLs reflecting the time (thus, the URLs are always changing).

To solve these problems, researchers at Purdue University are developing the software to retrieve data from heterogeneous sources.

This software requires a database that stores cameras' information (how to retrieve the data). The repository contains some examples of entries in a database (using MySQL).


Full documentation can be found at


sudo apt-get install libopencv-dev python-opencv
  • Install MySQLdb to access the MySQL database from Python:
sudo apt-get install python-mysqldb

Database Setup

  • Create an empty MySQL database using the following MySQL command:
  • Build the database using the provided file and the following Linux command:
mysql -u root -p cam2 < sample_database.sql
  • Modify the database credentials in the module:
DB_SERVER = 'localhost'
DB_USER_NAME = 'root'
DB_NAME = 'cameras'


  • is the main Python module. It archives images from a single camera.
  • provides classes to communicate with different types of cameras: IP cameras, non-IP cameras, and stream cameras.
  • is used by to parse JPEG and MJPEG streams.
  • contains custom Python Exceptions.
  • splits the retrieval job into threads for parallel processing.


Example usage can be found in the documentation.

This program downloads image snapshots from 2 sources

(1) A given URL address

(2) A camera ID in the MySQL database * MySQL database must be available on host computer.
