Everything You Need to Know about Home Security

SafeWise experts have years of firsthand experience testing the products we recommend. Learn how we test and review

When you hear the words “home security,” the odds are that you’ll start thinking about security systems, but it’s much more than that. Home security is not just about products—it’s a type of mindfulness you fit into everyday life.

Your home is a safe harbor where you weather the storms of life, from exhausting jobs to high gas prices to actual bad weather. Home security helps you think about how to protect that safety. Sadly, home security is sometimes about getting that safe place back after a break-in and doing your best to make sure it never happens again.

Covering everything means there’s a lot of information, so we’ll focus on the fundamentals of home security. We also added tons of links to SafeWise articles that explore these topics in depth so you can use this guide as a reference in the future.

Why home security matters

Whether you rent or own your home, it’s a refuge from all the scary things outside your door. But it takes a lot of vigilance to protect your home from threats. Threats can come from anywhere, but knowing what they are and how to ward them off is a huge comfort.

We could trot out statistics about burglaries, but there’s something more important: Once you know the motivations driving burglars and the things they look for, you start to understand home security as an essential mentality to strive for.

The biggest threat to your home’s security is a burglar looking for a quick score. If a burglar can’t get in fast enough or when nobody’s around, then the risks outweigh the rewards. Most burglaries aren’t elaborate heists with weeks of planning—they’re a mad dash with almost no prep.

Free ways to jumpstart your home security

You don’t need to start with a burglar alarm right away (especially if you’re waiting for it to come in the mail). A burglar alarm is a helpful tool, but you don’t need it to build good home security habits.

To learn more about the basic principles behind home security, check out our five d's of home security.

Here are some ways you can improve your home security without spending money.

Learn what to do if a burglar strikes

Here are some steps we cover in our article on what to do if your house is broken into:

  1. Leave the house and call 911. Always call the police if a burglar strikes your home, even if you think they’re long gone.
  2. Don’t touch anything. This helps protect crucial evidence the burglar might leave behind.
  3. Wait in a safe place. Get in your car or go to a neighbor’s house until the police show up.
  4. Take inventory. Find out what the burglar took so the police can file a report and you can make an insurance claim.
  5. Take care of kids and pets. A break-in is hard on everyone, so you may need to find ways to help kids and pets cope with the emotional aftermath.
  6. Clean up and get back to “normal.” Getting back to normal is a physical and mental process—it’s not about forgetting, but learning.
  7. Prepare for the future. Learn more about home security and what you can do (unless you started with this sentence, you’re already on track).
  8. Survey your home’s security. Scour every inch of your home with a thorough security assessment (see next section).

Conduct a home security assessment

A security assessment explores the small things that paint a picture of your house’s security like the types of locks you use, if someone can reach your windows, and if you know your neighbors (or roommates). If you don’t have a security mindset, it’s easy to miss gaps in your security. If you want to learn to spot the holes, check out our home security checklist.

After you finish your assessment, apply what you learned and build some new habits:

  • Set reminders on your smartphone to turn on lights at night.
  • Lock the door every time you go in or out.
  • Look for opportunities to improve your security.

Security systems

Alarm systems are some of the best tools to improve home security. They monitor your home using a suite of sensors like:

ismartalarm window door sensor

Door and window sensors (Also called entry sensors and contact sensors)


Garage door sensors

Security sensors have descriptive names 99% of the time—you usually know what they do by what it says on the tin. Check out our article on what to look for in a home security system to learn more about each type of sensor.

Start small

Stick with entry and motion detection if you have a tiny budget. Your system needs to detect burglars first and foremost—you can always add other kinds of sensors later on.

Every device in a system communicates with a control panel, which contacts a monitoring center when the alarm goes off—if you pay for a professional monitoring plan. The monitoring center verifies the type of alarm and alerts emergency responders to come to your home.

Most smart home security systems have a mobile app that helps you control everything from your smartphone. This is a killer feature for helping you build your home security habits because alarm systems don’t work when you forget to arm them. If you don’t have a smartphone, you can usually get a cheap key fob for quick arming.

Types of security systems

There are four classes of security systems:

  • Professional security systems take a traditional approach that comes with professional installation, has lower starting costs, and almost always requires a long-term monitoring contract. It’s the most expensive type of burglar alarm.
  • DIY home security systems make you install all of the equipment yourself (it’s easier than you think), though you’ll pay for it all beforehand. DIY security systems are perfect for renters since they usually don’t have a contract. Instead, you pay for professional monitoring month to month.
  • Self-monitored security systems also make you pay for all equipment up front, but there’s no professional monitoring. They rely on you to respond when an alarm goes off. This is the cheapest kind of alarm system because there are no monthly fees.
  • Takeover systems use old security system equipment you might have in your house and connect it to security monitoring from a different company.

Monitoring and equipment costs

Monthly monitoring fees

According to our most recent proprietary research of monitoring prices from 144 national and local security companies, the national average price of alarm monitoring is around $32.00 a month. But you can expect to pay more if you get special features like security cameras and smart home devices (e.g., smart locks, smart lights, and thermostats).

Equipment costs

We also researched equipment costs across 12 national security providers to find the average cost of devices. Here’s a small table with our findings.

Equipment type

Average cost per device

Door and window sensors


Motion detectors


Glass break sensors


Smoke detectors


Carbon monoxide detectors

Installation costs

Plan to pay between $99 and $199 for professional installation. You won’t pay for installation on DIY home security systems.

Security cameras

There are two ways to approach security cameras: they can either add to security systems or work as a cheaper, standalone alternative.

Security cameras in alarm systems

Adding a security camera (or video doorbell) to your home alarm system lets you view live footage in your security system’s app. This is convenient if you already have a security system, but it comes with a big drawback: you need to pay for the most expensive monitoring plans to get cameras.

In some cases, this adds only $5 to your monthly bill, which is comparable to what you pay for cloud storage on standalone security cameras. Unfortunately, you’re more likely to spend at least $15 more on your monthly bill.

Even with security cameras in your system, security companies don’t watch your video unless there’s an alarm. The monitoring station doesn’t assign someone to watch over your home 24/7—they react only when there’s a reason to do so.

Another reason to add security cameras to an existing system is that some cities require video verification after an alarm before dispatching police to your home. Video verification also helps you avoid false alarms, which can land you a costly fine.

Save some trouble

Master the habit of downloading important video clips from your security camera as soon as possible. Security cameras delete old videos so they can keep recording.

Standalone security cameras

We think a camera is a nice middle-ground solution for folks that can’t afford $30 a month for a security system. If nothing else, you’ll have video proof of neighborhood cats taking an unusual interest in your flower beds.

Some cameras even have facial recognition, so your partner and kids don’t trigger a constant barrage of real-time alerts when they pass by.

Unless you go with a camera that stores video on a microSD card, you can expect to pay for cloud video storage. This costs between $5 and $10 a month on average, depending on how many cameras you have.

With advanced features like these, you get what amounts to a mini security system. Security cameras aren’t a perfect replacement for security systems since they don’t have door and window sensors or professional monitoring.

"If you can only invest in one piece of security equipment, make it an outdoor security camera or video doorbell with motion detection, two-way talk, and mobile alerts."

—Rebecca Edwards, SafeWise

This is a far cry from just 10 years ago when security cameras weren’t easy to install and were so expensive that most consumers didn’t buy them.

Security cameras aren’t only about the video. Most security cameras send smartphone notifications when they detect different types of activity:

  • Motion
  • Sounds
  • People

Five innovations make security cameras very affordable today:

  • The home Wi-Fi network
  • Fast internet speeds
  • Smartphones
  • Easy installation
  • Cloud storage

How much internet speed do I need to use a security camera?

Depending on your camera and home security system, you need upload speeds of at least 2 Mbps per camera. So if you have four cameras, you need an upload speed of at least 8 Mbps—and that's on top of requirements for any other devices connected to your home network.

Other security solutions

A lot of home security products don’t fit neatly into a security system but can add an extra bit of protection depending on the layout of your house.

Indoor security

  • Consider replacing your front door with a security door that can resist forced entry. You can get a door with a solid wood core, metal cladding, or even a reinforced screen door for summertime airflow.
  • If you’re not ready to get a new door or want to save a few bucks, try a door jammer to reinforce your existing door. Door jammers are basically doorstops on steroids.
  • If your windows didn’t come with locks or offer only basic fasteners, you could get aftermarket window locks or window security film. These can be especially helpful on ground-level windows that are easy to reach.
  • Just like the smaller windows in your home, you can also find ways to secure your sliding glass door if all you know is the classic life hack of putting a big stick in the sliding track.
