a lot of companies charge an arm and a leg for their stuff, so I'm thinking going with a basic type system through a company, like door alarms, window sensors and a motion detector (only activate that when I leave). I'm thinking of adding one on the garage door too, especially after seeing that video above
I have a series of cameras with night vision that I bought from Frys a few years back that will send me an email if they sense movement, I can rig that up to send me a "email" text message.
Also, I have flood lights around the house and ordered motion sensors for them yesterday. I saw someone before who hooked up strobe lights on a motion sensor that was placed 5' off the ground on the front and back of his house with garage door closing sensors.
When I first moved in, I ordered a motion sensor online to put around the back of my house. It backs up to woods and its pretty dark all around, but the company was out of stock and refunded my money... never replied to any emails after that so I guess they went out of business.
Most of the stuff you can do yourself, but some insurance companies (like mine) will only give discounts if it is a professionally installed alarm system
