During the past month, I've started two threads about these topics. They
generated good responses, indicating a wide interest. So I'm offering
the results of my research over the last month here.

For books, I can recommend "Essential Home Security" by Stan Wasilik.

For a website: http://www.youtube.com/watch?v=316AzLYfAzw

Of course, the book and site overlap in many areas. The book's strength
are the many checklists for evaluating home vulnerabilities and pointing
out behaviors that may encourage theft (using an expensive laptop in a
public place and having a burglar follow you home and smash a car window
to steal it).

The website is better regarding hardware. The site is not just a front
for preferred products that it sells. It offers great tutorials and
unbiased reviews of commercial systems.

I'm not claiming that this book or site is the very best. But they are
excellent starting points, and together probably offer all the
information you need.

One tidbit I gleaned from another source has to do with garage doors
operated by electric openers. Pretty well explained he

Of course, you can also seal the gap someway, and not just with a trim
piece that can easily be removed with a putty knife.
