Part III: Home Security > Watch Your House Across the Network

Chapter 12. Watch Your House Across the Network

What You Need
  • Three or more wireless cameras

  • Wireless video receiver (compatible with wireless cameras)

  • The X10 Firecracker Computer Interface (CM17A) and an X10 wireless transceiver, or the X10 Powerlinc Serial Controller (CM11A)

  • Eight AAA batteries

  • A stable, broadband Internet connection that allows inbound connections

  • A computer running Windows (though you can do this project with Linux, too, with a bit of modification)

  • A video capture card with composite video input

  • Sticky poster adhesive

For a list of specific parts used in this project, refer to Exhibit A at the end of this chapter.

Chapter 13, Build a Security System, builds a real-time alerting system for your home. But what do you do when you actually receive an alarm? If you're at work and you get a message from your security system that a window was opened, it would be very nice if you could just take a look at that window before you rushed out to your car and drove home, especially since you'll probably discover that your cat knocked the alarm out of place.

This project provides you with a way to visually inspect your house from across the network using real-time video. Sure, everyone has a webcam, but this project is a bit different. We'll be monitoring several places around your home, so we'll need multiple cameras as well as the ability to switch between them. Since the cameras will be spread around the home, we can't rely on directly connecting the cameras to the computer. We'll need to find a way to get the video from the camera back to the computer that will stream it across the Internet.

If you're a webcam geek, you'll find this project interesting. The end result is a multi-camera system, where a user can click links on a web page to switch between the cameras. You can add as many as eight different cameras, so you could probably have one in each room of your home.

Figure 12-1 shows the conceptual architecture of this project. You visit a web page, and relay commands to your computer by clicking on links. Your computer controls multiple cameras, and determines which camera is currently active. The computer feeds the live video across the Internet to the your video player, which is embedded in a web page.

Figure 12-1. This project's conceptual design is basically the same one used by any closed-circuit camera system.
