Today my car got stolen from my house, and it is possible the person who did it has access to my home. I try to take secure measures online to maintain security, yet it seems I never paid attention to my house.

As an IT Security practitioner and fan, I am interesting in applying my knowledge and secure my house. What are some methods or approaches I can take as an IT guy, to secure my house? It would be great if I could maintain entry logs, get notification of unusual activity, protect computers left at home, and so on. 

I was thinking of a linux server, and gadgets such as sensors and webcams.
