“You do not need a fortress. You need your house to be a worse choice than the ones around it.”

— Brett Davis
The Home Defense Bible — first edition
I · The Book

A working manual, not a book about fear.

I spent nineteen years in residential security. I started as a locksmith's apprentice doing lockouts and rekeys, moved into alarm and camera installation, and finished doing security assessments for homeowners and small landlords — which mostly meant walking through somebody's house and telling them the truth about it.

I have re-hung more kicked-in doors than I can count, and I have sat at a lot of kitchen tables the morning after with a family that did not sleep.

“Almost nothing that happens in a break-in is exotic. The house was picked because it looked easy.”

Every chapter here has a part number, a price, a Saturday afternoon attached to it, or a sentence you can practice out loud at the kitchen table. If a thing does not make your house harder to get into, or does not help you decide faster when it counts, it is not in this book.

And every chapter closes with a section called What This Won't Do — because a security book that only tells you what works is doing you harm.

II · The Difference

Most people spend money on the wrong half of the problem.

A hundred-dollar deadbolt in a soft pine frame is a few seconds with a shoulder. The frame is the whole job, and nobody sells you the frame.

What most homeowners do

  • Buy the expensive lock, keep the builder's strike plate and its three-quarter-inch screws
  • Harden the front door — the one nobody in the family actually uses
  • Pay a monthly bill for a system nobody is confident arming
  • Shop cameras by megapixel, then hang them too high to identify a face
  • Hide a key somewhere clever
  • Have no plan for two in the morning, so the plan gets invented at two in the morning
  • Never find out where any of it stops working

What this book does

  • Anchors the strike plate into the stud with three-inch screws — the cheapest seconds you will ever buy
  • Starts with the door your family actually uses, and the garage side door behind it
  • Gives you the honest breakdown of monitored versus self-monitored before you sign anything
  • Places cameras for identification, not coverage
  • Walks your house the way a stranger walks it (Ch. 5), then does the free fixes first (Ch. 6)
  • Writes the safe room, the 911 call and the ten-minute drill down in advance
  • Closes every chapter with What This Won't Do

IV · Reader Results

What readers did with it first.

★★★★★

“I read Chapter 8 on a Saturday morning and had three-inch screws in every strike plate in the house by lunch. Eleven dollars. I had spent four hundred on a lock the year before.”

Ray M. · Ohio
★★★★★

“The walkthrough in Chapter 5 was the uncomfortable part. Side gate unlatched, ladder against the shed, and a knob lock on the garage door into the kitchen. All of it fixed in a weekend.”

Denise W. · Texas
★★★★★

“We ran the ten minute drill with the kids. My nine-year-old knows where to go and what to say on the phone now. That is the part I could not buy at the hardware store.”

Tom & Sarah K. · Pennsylvania

V · About

Brett Davis

Nineteen years in residential security. Locksmith's apprentice first — lockouts and rekeys, mostly — then alarm and camera installation, then the last stretch of it doing security assessments for homeowners and small landlords.

That last part is where this book came from. An assessment is not a sales call. It is walking through somebody's house and telling them the truth about it: this door is fine, that frame is decorative, the money you spent on the front went to the side of the house nobody can see from the street.

I wrote this for everyone who has stood in their own doorway at two in the morning with a flashlight and no plan. This is the plan. Everything before Part Nine is designed so that Part Nine never has to happen — that is the whole point of the book.

VII · Questions

Straight answers.

Is this a fear book? I don't want to scare my family.

No. It is a working manual. There are no statistics in here designed to keep you up at night. Almost nothing in a break-in is exotic — the house was picked because it looked easy — and nearly all of the fix is hardware, light, sight lines, and one conversation at the kitchen table. Most of this book is a Saturday afternoon and a trip to the hardware store.

Your videos are free. Why buy this?

The videos are one fix at a time, in whatever order I thought to film them. The book is the whole walkthrough, in the order I would actually do it in your house — audit first, free fixes second, the door your family uses third — with the part numbers, the prices, the time each job takes, and the point at which each fix stops working. That last part does not fit in a video, and it is what keeps you from putting a hundred-dollar lock on a hollow door and calling it done.

Why only $27?

Because the whole book argues that the right fixes are cheap and the expensive ones are usually wrong, and I would look ridiculous charging two hundred dollars to say it. $27 is about a box of three-inch screws and a decent strike plate. If the book is worth anything, Chapter 8 pays for it before you finish the morning.

What format is it, and how do I get it?

A PDF, delivered the moment you check out. It reads on a phone, a tablet or a computer, and it prints cleanly if you would rather carry the audit sheet around the house with a pencil — which is how I use it. Instant download, yours forever.

I rent. Is any of this useful to me?

A good part of it, yes. The audit, the free fixes, lighting, the lived-in look, answering the door, package theft, neighbors, the family plan and the whole of Part Ten apply whether or not you own the building. Where a fix needs a landlord's permission or a drill, I say so in the chapter and give you the version that does not.

Do I need to buy a lot of equipment?

No. Chapter 6 is nothing but the free fixes and the five dollar fixes, and it is worth more than most of what people buy. Three to five minutes of delay is functionally a wall for the ordinary break-in, and in most houses that is two or three hundred dollars and a couple of weekends. Appendix B lays the plan out at several budgets so you can see where your money goes furthest.

Does it cover firearms and the law?

Part Nine does, narrowly and carefully. It covers escape as the plan, how to think about the decision before the night it matters, storing things safely, and when to go get real training. It is informational, not legal advice — I am not a lawyer and I am not your instructor. Laws on self-defense, weapons, cameras and recording vary widely by state and change often, so confirm anything in Part Nine with a licensed attorney where you live.

Wait — one thing

Less than one wrong lock.

People spend four hundred dollars on the wrong hardware every day. $27 gets you the whole walkthrough first — sixty chapters, the audit sheet, and the limit of every fix — so the money goes where it actually buys you seconds.
