What is not a physical security measure for your home

Hey folks, I’ve been writing about home stuff for years now—everything from remodeling kitchens to dealing with creepy crawlies in the basement—and home security always comes up a lot. People get confused about what actually counts as physical security for their house, especially with all the smart gadgets out there these days. So let’s clear this up straight: physical security measures are the tangible, touchable things that directly block, delay, or deter someone from getting into your home or messing with it.

Things like deadbolt locks on doors, reinforced strike plates, window bars or security film, sturdy fences around the property, motion-activated floodlights, security cameras (the hardware itself, like the mounted units and sensors), alarm system components such as door/window contacts, glass break detectors, and sirens—these are all physical because they’re physical barriers or devices installed on your property that make forced entry harder or noisier.

Now, the flip side—what is NOT a physical security measure. A lot of stuff gets lumped in that shouldn’t be, because it’s more about procedures, digital stuff, or response after the fact.

First off, cybersecurity things. Strong passwords for your smart home apps, two-factor authentication on your accounts, avoiding phishing emails, or updating your router’s firmware—none of that is physical. It’s crucial for keeping hackers from remotely unlocking your smart locks or spying through cameras, but it doesn’t physically stop someone from kicking in your door.

Alarm monitoring services or app notifications. Getting a push alert on your phone when a sensor trips or having a company call the cops—that’s a service, not physical. The sensors might be physical, but the remote monitoring and alerts are operational or administrative.

Homeowners insurance. Yeah, it covers losses if you get burglarized, but it’s financial protection, not a barrier. It kicks in after something bad happens; it doesn’t prevent it.

Neighborhood watch programs or just being buddies with your neighbors and watching each other’s places. That’s community vigilance, which is smart and effective, but it’s procedural—people talking and keeping an eye out, not a physical object.

Hiding a spare key outside, like under a rock or in a fake plant. That’s actually a bad idea altogether because it’s a huge vulnerability, but even if done right, it’s not a security measure—physical or otherwise. It’s convenience that weakens security.

Policies or habits like discussing online safety with your family, monitoring kids’ internet friends, or having emergency plans. These are administrative or educational measures, important for overall safety, but not physical.

Even things like yard signs saying “protected by XYZ alarm company” or fake camera decoys—the signs are more deterrent psychology than physical, and fakes obviously don’t do anything real.

The point is, physical security is about layers of stuff you can see and touch that make your home harder to breach right there on site. Everything else supports it, but if you’re focusing on home hardening, stick to the hardware and barriers first. Layer in the non-physical stuff on top for better overall protection. I’ve seen too many folks rely on apps and alerts alone and then wonder why a determined burglar still got in. Build the physical foundation solid, and the rest works better. That’s how I’ve approached it with my own place over the years.
