This book recounts how I started off with a few X10 modules to control the lights and appliances, and ended up making a video recording of a burglar as he tried to break into my home while I was away on vacation. And you can have the same system! I'll show you what to buy, and how to hook it up, and even more importantly, what to avoid. I've already made all the mistakes, so you won't have to!Ladies, you can do it! As a woman who lives alone, I am hyper-vigilant about safety and security. When I moved into my new home, I couldn't afford an expensive alarm system and monthly monitoring fees. I did some research, looked at other books on the same subject and was very happy to find this book about how to set up a low-cost home security system, using X10 components. I found the book very easy to read and understand, with pictures illustrating every piece of equipment. The author included many personal examples, making it both fun and interesting to read. Now, when someone comes to my door, I can see and hear who is on the other side before opening it. I can even answer the door with my telephone, and talk to whoever is outside. I highly recommend this book to anyone who wants to be safe and secure at home!
