When researchers interview convicted burglars about target selection, a surprising pattern emerges: most decide whether to break into a home within 30 seconds of first seeing it. This isn't random opportunism—it's a rapid assessment process honed through experience, where specific visual cues trigger an almost automatic go or no-go decision.

Understanding this quick evaluation process transforms how we think about home security. Rather than focusing on catching criminals after they've already chosen your home, the evidence points to making your property an unappealing target from the start. The research reveals that burglars look for three key factors during their brief assessment, and addressing these can dramatically reduce your risk.

Research interviews with over 400 incarcerated burglars reveal a consistent pattern in target selection. Within half a minute, experienced burglars assess accessibility, visibility, and occupancy indicators. They're looking for homes with multiple escape routes, poor sightlines from neighboring properties, and clear signs that nobody's home. One study found that 83% of burglars specifically check for alarms, but here's the twist—they're not deterred by the alarm itself but by what it suggests about the homeowner's security consciousness.

The accessibility assessment happens almost instantly. Burglars note unlocked gates, open windows, tools left outside that could aid entry, and hiding spots near doors. They particularly favor homes with tall fences or dense shrubs that provide cover—features homeowners often install thinking they increase security. Research shows that homes with good natural surveillance—clear sightlines from the street and neighbors—experience 50% fewer burglaries than those with extensive privacy features.

Occupancy cues carry enormous weight in the decision. Accumulated mail, newspapers, or packages signal absence. But burglars also notice subtler patterns: cars always gone during certain hours, blinds that never change position, or lights on predictable timers. Studies indicate that homes showing clear signs of irregular occupancy patterns are three times less likely to be burglarized than those with predictable routines.

Not all security measures work equally well, and some popular options are essentially theater. Fake security cameras, for instance, fool almost no one—experienced burglars can spot them immediately by their lack of wiring, poor positioning, or the absence of indicator lights. Similarly, 'Beware of Dog' signs without actual evidence of a dog (no bowl, toys, or worn paths in the yard) are ignored. Research shows that generic security company stickers are only marginally effective unless accompanied by visible cameras or alarm boxes.

What actually deters burglars surprises many homeowners. Real cameras positioned obviously at entry points reduce attempts by 60%, but hidden cameras have no deterrent effect—they might help solve crimes but don't prevent them. Motion-activated lights work, but only when combined with good sight lines; lights in secluded areas just help burglars see better. The most effective deterrent? A car in the driveway, especially one that varies its presence unpredictably.

Dogs present an interesting case. Large dogs don't deter significantly more than small dogs—it's the noise factor that matters. A yapping terrier that alerts neighbors is more problematic for burglars than a quiet German Shepherd. However, the strongest deterrent remains human presence or its convincing simulation. Studies show that homes with visible activity—varying lights, moving curtains, or TV sounds—are avoided even when burglars suspect simulation, simply because the risk calculation doesn't favor taking chances.

The most robust finding in burglary prevention research might also be the most low-tech: strong neighborhood social connections reduce burglary rates more than any security hardware. Studies consistently show that blocks where neighbors know each other's names and routines experience 25-40% fewer burglaries than anonymous neighborhoods, regardless of income level or security investments. This isn't just about formal neighborhood watch programs—it's about collective efficacy, the willingness of neighbors to look out for each other and intervene when something seems wrong.

Burglars actively avoid neighborhoods displaying social cohesion. They notice when neighbors chat regularly, when kids play together in front yards, when people walk dogs at varying times. These behaviors signal that strangers will be noticed and questioned. One fascinating study found that simply increasing the number of residents who spent time in their front yards reduced daytime burglaries by 33%. The presence of neighborhood social media groups or communication systems adds another layer—burglars know that suspicious behavior gets reported quickly in connected communities.

This social protection extends to individual homes through reciprocal watching arrangements. Research shows that having even one neighbor who actively watches your home during absences reduces burglary risk by up to 50%. This informal surveillance proves more effective than many technical solutions because it's unpredictable and responsive. Unlike cameras that can be avoided or alarms that can be defeated, nosy neighbors represent a dynamic, thinking deterrent that adapts to suspicious behavior in real-time.

The 30-second decision window that burglars use to assess targets reveals an important truth: effective home security isn't about making your home impenetrable—it's about making it an obviously bad choice compared to alternatives. The research consistently shows that burglars are rational actors who seek easy targets with low risk and quick escape routes.

By understanding what burglars actually look for—easy access combined with concealment, clear signs of absence, and social isolation—homeowners can make evidence-based decisions about security. Often, the most effective measures cost nothing: varying routines, maintaining sight lines, and building neighborhood connections provide better protection than expensive security theater.
