Home Invasion Tactics, Part A: The Watcher and the Knock and Wait

By Larry Betz | Prepared Not Paranoid https://www.preparednotparanoid.com/


Most break-ins don't start at the door. They start days earlier, from the sidewalk. Before a criminal ever touches your lock, he's already learned when you leave, when you come home, and whether anyone answers when he knocks. Knowing how burglars choose a house is the first step to taking your home off the list.

Burglary vs. Home Invasion

A burglar wants your property, not you, and prefers an empty house. A home invader knowingly goes into a home where people are inside and is ready to confront them.

Here's how the two compare.

According to the Bureau of Justice Statistics, a household member was home during roughly 28% of household burglaries, about 1 million a year, and someone was hurt or threatened in about 7%. That report covers 2003 to 2007, and it's still the most detailed national look at this question. Burglary has dropped a lot since then (police recorded about 675,000 in 2025), but the lesson holds: you can't assume a break-in only happens when no one is home.

Deception Comes Before Force

Most people picture a criminal kicking in a door. Many prefer something much easier: getting you to open it. Security professionals call this social engineering, getting past people instead of getting past locks.

Most of their tactics fall into three categories.

Here's how they break down, and where each one is covered in this series.

Criminals Follow a Process

  1. Pick a possible target.

  2. Gather information.

  3. Test the home and the people in it.

  4. Create or wait for an opportunity.

  5. Use that opportunity.

Every step in that process is a chance for you to notice. The Watcher and the Knock and Wait are steps 2 and 3. Catch them there, and you've broken the chain before anyone reaches your door.

Tactic 1: The Watcher (Casing the Area)

What it is: Someone watches a home, a street, or a family's routine to find the weak spots and the best time to strike. The person usually looks completely ordinary: a jogger, a dog walker, a delivery driver, or someone just passing through.


What it can look like: the same car parked on your street several days in a row with someone sitting in it, or a person walking the same route at the same time, looking at houses instead of where they're going.


Why it works: Most people don't notice someone who blends in, predictable routines make it easy to know when a home is empty, and most of us see something a little off and decide "it's probably nothing." In the UNC Charlotte study from Part 1, about 83% of burglars said they tried to find out if a home had an alarm before breaking in. That's casing.

Quick wins:

  • Make your layers visible: cameras that can be seen, alarm signs, and motion lights.

  • Don't post your schedule or "we're away" photos online.

  • Know your neighbors and agree to tell each other when something seems off. Your police department's alerts and CrimeMapping.com show what's already happening on your street.

One sighting is usually nothing. A pattern is worth writing down. The Safest House on the Block lists every warning sign and the full set of steps to take your home off a Watcher's list.

What to Write Down

If something keeps showing up, start a simple log on your phone from a safe place: the date and time, what you saw and where, a description of the person, the vehicle and plate if you can see it safely, and which way they went. That kind of detail helps police connect what you saw to other reports. Never follow or confront anyone. If a crime is happening right now, call 911.

Tactic 2: The Knock and Wait (The Occupancy Test)

What it is: Someone tests whether a home is empty before trying to break in. They knock, ring the bell, leave a flyer, or pretend to deliver a package, and then watch what happens. If no one answers, they often walk around toward the side or back door.

Why it works: A lot of people ignore an unexpected knock. That silence tells someone exactly what they wanted to know.

Here's how to tell the difference between a real visitor and someone testing your home.

The one habit that beats it: acknowledge the knock without opening the door. Speak through a video doorbell, an intercom, or the locked door. Silence says "no one's home." A voice says "someone is." The book covers the rest, including how to make the house look lived in when you're away and which doors and windows to harden first, since that's where someone goes after no one answers the front.

What to Say at the Door

You don't owe a stranger an explanation, and you never have to open the door to have the conversation.


Safe and non-engaging:

  • "We're not interested, thank you."

  • "We don't take anything at the door. Have a good day."

Setting boundaries:

  • "I don't open the door for anyone I'm not expecting."

  • "If you're with a company, leave a card. I'll call them myself."

If they persist:

  • "You need to leave my property now."

  • "I'm calling the police." Then do it, and stay inside, away from the door.

SCAN at the Door

  • S - See your environment. Look at the camera first. Is there a vehicle? Is anyone else in the yard or near the side of the house?

  • C - Create space. Keep the door closed and locked. The door is your space.

  • A - Act deliberately. Answer, keep it short, and verify anything they claim on your own.

  • N - Never doubt your gut feelings. If it feels wrong, don't open the door.

The Prepared Protector is someone who's decided that loving someone means being ready for them, not just hoping things go fine. Teaching your family how to handle a knock at the door is one of the simplest ways to do that.

Ask Yourself

  • Is my daily schedule easy to figure out from the street, or from my social media?

  • If someone knocked right now and no one answered, what would my house tell them?

  • Does everyone in my house, including the kids, know not to open the door to someone we're not expecting?

Remember

Criminals pick a home before they pick a lock. They watch, they knock, and they wait to see what you do. Notice the pattern, answer through the door instead of opening it, and keep your layers visible.
