Residential street at dusk — front doors, hedges, lighting

Most people picture a burglar as someone in a black turtleneck, casing your house for weeks, waiting for the perfect window. That's a movie. The real version is less cinematic and significantly more depressing: it's usually someone who walked past your house, noticed something that made your place look easier than the next one, and acted within 60 seconds of that decision. No turtleneck. No plan. Just opportunity, recognized and taken.

Understanding that distinction — between the fictional professional and the actual opportunist — is the single most useful thing you can do for your home security. Because once you know what they're actually looking for, the countermeasures become obvious. And a lot of the stuff you've already spent money on starts to look like expensive decoration.

How Burglars Actually Think

The three types — and why most aren't who you imagine

Criminologists who study residential burglary consistently find the same thing: the offender population isn't homogeneous. There are three rough categories, and the category matters a lot for what actually deters them.

Type 1: The Opportunist (most common)

No pre-planning. No surveillance. They're walking, driving, or riding through a neighbourhood and they notice an unlocked door, a car that hasn't moved in five days, or a house that clearly has nobody home right now. The decision is made in under a minute. They go in, take what's visible and portable — cash, a laptop, a game console, jewellery they spot immediately — and they're gone in under ten minutes. Noise or any sign of resistance sends them straight to the next street.

Research from the University of North Carolina's criminology department, which interviewed 422 convicted burglars, found that most couldn't describe a "plan" at all. They described recognizing an opportunity and taking it. This matters because opportunists are deterred by friction — anything that makes your house look harder or riskier than average.

Type 2: The Semi-Professional (less common)

Does some reconnaissance — usually a day or two, not weeks. Might knock on the door pretending to be a delivery driver to confirm nobody's home. Has a routine and preferred targets (usually a specific type of house in a specific income bracket). More sophisticated entry techniques. Still not carrying lockpicks; more likely to use a dedicated kick-in tool or simply know which windows are typically flimsy. Usually sells to a fence with a pre-existing relationship.

Type 3: The Professional (rare)

Actually studies the target. Has a buyer lined up before the job. Has specific tools, specific skills. Targets high-value properties with specific items in mind — art, specific jewellery, financial documents. This is the movie burglar. They exist. They represent a tiny fraction of residential burglaries and are almost entirely irrelevant to the average homeowner's threat model.

⚡ The "Know Thy Enemy" Number

FBI crime statistics consistently show residential burglary with no forced entry at roughly 30–35% of all cases. That's one in three burglaries where the door was either unlocked, or so easy to open it barely counts as locked. Your first line of defence isn't a deadbolt — it's actually locking the door.

"The vast majority said that if a target looked too complicated or risky, they'd simply move to the next one. Nobody is married to your specific house."

What They See From the Street

The signals your house is broadcasting — and what they mean to the wrong person

Target selection for an opportunistic burglar happens in seconds and is based almost entirely on visual cues from the street or a quick walkup. Here's what they're actually reading:

Occupancy signals

The single biggest deterrent to a residential burglar is the possibility that someone is home. Not a security system. Not a camera. A light on, a car in the driveway, a TV flickering. The UNC Charlotte study found occupancy concern was the most frequently cited reason for abandoning or avoiding a target — more than cameras, more than dogs, more than neighbours.

The flip side: a driveway with no car, a dark house at 11am on a Tuesday, curtains all drawn the same way for three days straight, or mail and flyers visibly accumulating are all signals that say "nobody's home and they might not be back for a while." These are the houses that get hit.

Cover and concealment

Tall hedges next to the front door. A fence that blocks sight lines to the side of the house. A gate with a privacy screen. A garage that's positioned so the entry door isn't visible from the street. All of this sounds like privacy — and it is privacy. The problem is it provides privacy to the burglar too. The most dangerous approach vectors in any house are the ones not visible from neighbours or the street. Burglars know this, and they use it.

Visible rewards

A mountain bike leaning against the back gate. A luxury car in an unlocked garage. Amazon boxes piled up (signals: people with money who aren't home right now). A ring camera in the box it came in, sitting on the porch. New appliance boxes by the recycling bin. Any of these, visible from the street, changes the calculus on whether your house is worth the attempt.

Soft points they can see

Old single-pane windows with latches. A side door that's a hollow-core slab in an old frame. A basement window at ground level with no bars. A pet door large enough to reach through and hit an interior knob. A detached garage with a wooden door and an old padlock hasp. Experienced burglars read door and window quality the way a locksmith does — just with different intentions.

⚠ The "I Have an Alarm" Sticker Problem

Alarm company yard signs and window stickers are a mild deterrent at best, and potentially counter-productive. They signal: (a) there's probably valuables worth protecting in here, and (b) the owner is security-conscious enough to have an alarm but maybe not much else. A sign without visible cameras or solid doors is often read as "has sticker, may or may not have system." It's not zero value — but it's much less than people assume.

Entry Methods That Actually Get Used

Not movies. Not Mission Impossible. What the data actually shows.

Forget lockpicks. Forget glass cutters. Here's what the FBI and Bureau of Justice Statistics data consistently shows for how residential burglaries actually happen:

34%

Front Door

Either unlocked, or kicked in. A standard door-frame kick takes two seconds and a single forceful heel strike. Most residential door frames fail — not the lock, the frame and the strike plate screws.

23%

First-Floor Window

Unlocked is easiest. Older single-pane windows can be shimmed or popped. Sliding windows often lift off their tracks entirely with no tools. Almost always concealed from the street.

22%

Back Door

Less visible than the front, often cheaper construction, frequently has a glass panel adjacent to the knob. Sliding glass doors are routinely vulnerable to simple lift-and-pop or a bar in the track being missing.

Garage Door / Side Entry

Attached garages with the interior door being a hollow-core slab are a major vulnerability. Older garage door openers can sometimes be opened with universal remotes. The side human-door on garages is often the weakest door on the property.

The kick-in problem specifically

A deadbolt is only as good as what it's anchored to. The standard residential door installation uses 3/4-inch screws into a soft-wood jamb — and when a 200-pound person kicks a door just below the knob, the entire frame splits in one strike. The bolt held. The wood around it didn't. This is why a high-security deadbolt paired with a flimsy strike plate is basically a false promise. The fix is a reinforced strike plate with 3-inch screws into the stud — a $15–$30 hardware investment that genuinely changes the physics of a kick-in attempt dramatically.

What about picking?

Extremely rare in residential burglary. Takes skill, takes time, leaves no visible evidence which is actually a concern for a burglar (they prefer to know they got in, not wonder if a neighbour saw them standing at a door for two minutes). The locksport community spends enormous energy on picking — and essentially zero burglars do. Bump keys exist and were briefly a concern, but quality deadbolts with security pins have addressed this for years.

✓ The Real Lock Upgrade Priority Order

First: Reinforce your door frame and strike plate (3-inch screws into studs). Cost: ~$20.
Second: Deadbolt on every exterior door — ANSI Grade 1 minimum. Cost: $50–$120.
Third: Window locks that actually engage (not just latches). Cheap and often overlooked.
Fourth: Solid-core door on the interior garage-to-house passage if you have an attached garage.
After all that: Consider upgraded deadbolts, smart locks, cameras.

When It Actually Happens

The timing data will surprise you — it surprised us

Most people imagine burglaries happening at 2am under cover of darkness. That's the movie version again. Real residential burglary peaks at a very specific, very counterintuitive time: weekday business hours.

Bureau of Justice Statistics data shows the highest concentration of residential burglaries between roughly 10am and 3pm on weekdays. Think about why: that's when houses are most likely to be empty (people at work, kids at school), it's bright enough to see what you're doing, and a person walking up to a front door looks less suspicious in daylight than they do at midnight.

The 6pm–midnight window has elevated rates too — the evening departure window when people go out for dinner, entertainment, or errands. Late-night burglaries happen but are statistically much rarer, and when they do occur, they're more likely to be the semi-professional category who specifically targets sleeping households (a different and considerably more alarming crime profile).

📅 Seasonal and Situational Peaks

Summer months see elevated rates — windows left open, irregular schedules, vacation absences.
Post-holiday period (late December into January) is a known peak — empty boxes advertising new electronics, plus cash-poor offenders post-holiday season.
After you post on social media that you're away is not a myth. Multiple studies have confirmed burglars actively monitor social media, especially in areas they operate in.
During neighbourhood events that pull residents away from their blocks (street fairs, games, local events).

What Actually Works vs Security Theater

The honest breakdown — including the stuff that just makes you feel safer

This is the section that's going to hurt some feelings — and cost some companies some business. Here's the honest assessment of common residential security measures, based on what the criminology research actually shows about deterrence.

Measure	Verdict	Why
Reinforced strike plate (3-inch screws)	Actually Works	Dramatically increases kick-in resistance. Under $20. Most underrated security upgrade in existence.
ANSI Grade 1 deadbolt on every door	Actually Works	Real deterrent against kick-in when combined with a reinforced frame. Resists bump and basic pick attempts.
Visible security cameras (real ones)	Actually Works	Consistently cited as a primary deterrent in burglar surveys. The UNC study found 60% would avoid a property with visible cameras. Key word: visible.
Dogs (any size, audible)	Actually Works	Barking creates noise and uncertainty about occupancy. 65% of surveyed burglars said a dog would cause them to choose another target.
Motion-activated exterior lights	Actually Works	Eliminates cover of darkness at entry points. Cheap, reliable, and hard to ignore. One of the highest ROI security investments.
Timed interior lights when away	Actually Works	Simulated occupancy is a real deterrent. Smart plug timers are $10–$15 each and significantly change the visual signal a house gives from the street.
Alarm system (monitored)	Situational	Good deterrent before entry — less useful after. Average police response time in urban areas is 7–11 minutes. Most burglaries are complete in 8–12 minutes. The yard sign may matter more than the system itself.
Smart locks with apps	Situational	Remote access control is genuinely useful. Security against physical entry is roughly equivalent to a Grade 1 deadbolt — which is fine, but not an upgrade. Main vulnerability shifts to digital (weak PIN, Bluetooth intercept). Not better than a quality keyed deadbolt; different trade-offs.
Alarm company yard sign / sticker only	Minimal Effect	Some deterrent to the least sophisticated opportunist. Experienced burglars are largely unimpressed. Not useless — but nowhere near as effective as people assume.
Fake security cameras	Security Theater	More experienced burglars identify fakes easily (no IR glow at night, cheap housings, no cable runs). May give homeowner false confidence while providing minimal real deterrence.
Door chain/bar locks on their own	Security Theater	Adds friction when you're home but does nothing to frame integrity. The frame is what fails — the chain doesn't change that.
High-security padlock on a flimsy hasp	Security Theater	This is an NPZ classic complaint. Abloy on a $4 hasp is security for your lock, not your door. The hasp will be pried off in seconds. The lock is irrelevant.

"I've never picked a lock in my life. You kick the door, or you find a window. That's it. Nobody's got time for anything else."

Your Actual Action Plan

Prioritized by real-world impact, not by what's easiest to sell you

Based on everything above, here's the priority order that criminology research actually supports. This isn't the order that makes home security companies the most money. It's the order that actually reduces your risk.

Phase 1: The fundamentals ($50–$100 total)

Reinforce every exterior door frame with a proper strike plate and 3-inch screws into the stud — not just the door jamb. Add a Grade 1 deadbolt to any door that doesn't have one. Lock your windows, including secondary latches on double-hung and sliders. These three things address the actual entry methods used in the majority of break-ins and cost almost nothing compared to a "smart home security system."

Phase 2: Reduce occupancy signals

Smart plugs on a few interior lights set to randomized schedules. Stop letting mail or packages accumulate visibly. If you're going to be away, tell a neighbour — a car that moves in the driveway once in a while is worth more than a yard sign. Don't post vacation announcements on public social media until you're back.

Phase 3: Eliminate cover

Trim hedges and shrubs away from entry points so they can't be used for concealment. Make sure side-of-house and back doors are visible to at least one neighbour's sight line. Motion-activated lights on every dark approach path to the house — especially side and back. This one is chronically underrated.

Phase 4: Then do the camera and alarm stuff

Visible cameras at main entry points are a real deterrent and provide evidence value. A monitored alarm adds another layer. These are genuinely useful — they're just not as foundationally important as the first three phases, and people tend to skip the cheap fundamentals in favour of the expensive options because the expensive options feel more sophisticated. They're not. A deadbolt in a reinforced frame beats a smart lock in a stock $40 frame every single time.

✓ The One Thing That Matters Most

Make your house look like it costs more effort than the next one. That's it. That's the entire theory. You don't need to make your home impenetrable — you need to make it the second choice. Most burglars are choosing between multiple options on a street or in a neighbourhood. Be the house that's not worth the trouble, and the house that makes it obvious why.
