Preface
You’ll build a small control mechanism to enable the lock to trigger events
for a “welcome home” sequence. A little imagination can tie this project into
every other project in the book.
Chapter 12, Watch Your House Across the Network (written by Tony
Northrup), is an evolution of the pet monitoring project in Chapter 3. This
time, however, you’ll stream full motion video across your home network or
the Internet to peek in on your home’s multiple, inexpensive video cameras
from any web browser.
Chapter 13, Build a Security System (written by Tony Northrup), brings
physical intrusion detection, event processing, and alerting capabilities to
your home. While it’s possible to buy an affordable security system for your
home, it will usually require a monthly maintenance fee, and it won’t allow
you much control over the system’s behavior. After completing this project,
you’ll be able to configure your alarm system’s behavior to your family’s
tastes using a simple Perl script. You can even build an off-site video storage
system to securely store video evidence of a crime, even if your computer is
stolen in the process.
