'ZDNET Recommends': What exactly does it mean?

ZDNET's recommendations are based on many hours of testing, research, and comparison shopping.

You don't need to spend a fortune to secure your home, and thanks to mobile technology, your options now extend far beyond locking the front door.

Smart video doorbells record video and audio feeds in real time when you have visitors. Motion and sound sensors can be used inside and outside, along with smart locks and night-vision cameras.  

However, not all innovative home security products are created equally, and some are more costly to set up than others. A professionally installed system may get you more features, like professional monitoring and the ability to contact emergency services on your behalf, but could cost more if the provider requires a contract, installation fees, and a service subscription. If you want to go the DIY route, a few select devices can be enough to protect your home (and office) against intruders by alerting you when suspicious activity is detected, giving you peace of mind when you're away.

Also: What are the best security cameras for protecting your home?

We've rounded up the best home security devices suitable for different budgets and homes. Our top home security system is the Ring Alarm Pro Security Kit, a robust all-in-one solution perfect for protecting your home and all of its entry points, complete with 14 components and easy, DIY installation. 

Check out our other top picks for the best home security systems below to find the best protection for you and your property.

What are the best security systems of 2023?

Our top home security system is the Ring Alarm Pro Security Kit, a robust all-in-one solution perfect for protecting your home and all of its entry points, complete with 14 components and easy, DIY installation. 

Security systems that you can set up and monitor yourself tend to be the most popular. However, some systems offer subscriptions for people in higher-risk areas, providing professional monitoring or the ability to store and record footage. The best security systems on the market balance security, usability, and connectivity.

Which security system is right for you?

Today's smart home security products can offer you peace of mind both in and outside of your house. Unlike businesses, homeowners usually don't need to invest in heavy-duty solutions. Instead, a few carefully selected devices placed around your front porch, garden, and ground floor windows can be more than enough to protect your home.

We recommend at least one camera, a video doorbell, a smart lock, and window sensors if you're building your home security system for the first time. Large properties can also benefit from additional security devices.

How did we choose these security systems?

ZDNET experts have tested countless security systems over the years. We have surveyed the best security systems on the market to provide in-depth advice on how to protect yourself at home, at work, and online.

We have researched the best security systems on the market, weighed their pros and cons, and judged them based on price, ease of installation (for DIY systems), whether they offered professional monitoring services, smart features, and customer reviews. The main factors we considered when we decided on our top recommendations include the following:

  • Modern features: While selecting our recommendations, we ensured that each option has features you expect from modern home security systems, including high-resolution recording, mobile alerts, night vision, and sirens. 
  • DIY/professional: We wanted to include two main types of home security systems: ones that you can install and monitor yourself, and set-and-forget options you can leave in the hands of professionals. 
  • Versatility: You don't always need a home security system with piles of sensors, door locks, and cameras. Sometimes, just one or two well-placed security devices that you can select are enough. 
  • Budget: We know that setting up full systems, all at once, can be expensive. With this in mind, we selected options suitable for a variety of budgets. 

Why are sensors important in a DIY home security system?

Sensors are the key to effective, discreet home security. There are many different kinds of sensors, including infrared, magnetic, audio, and motion sensors. Their application depends on the type of security product involved.

Also: The best driveway alarms

For example, motion sensors are used for video doorbells and cameras, while other door and window products may combine motion and magnetic sensors to detect unauthorized entry.

Do you need an internet connection?

For smart home security systems, the answer is usually yes. Compared to business security systems that are often monitored remotely, home systems offer you power and visibility -- and this generally requires internet connectivity and a mobile device. 

Also: The best internet providers

Some products include both Wi-Fi and cellular connectivity, so your device can use a mobile network if your home hub fails.

Do you need a subscription?

Subscriptions aren't always required, but you may prefer one. Without a subscription, a basic security system may notify you when a sensor detects activity without providing access to video feeds or recordings. 

If you want access to your camera's feed history, it's worth signing up for a subscription. Plus, subscription services will usually sweeten the pot with additional security layers like professional monitoring, automatic emergency calls, or multiple device monitoring.

Are there alternative home security systems worth considering?

While our top picks for the best security system can suit a variety of functions and uses, maybe all you need is a standalone camera or two. You don't always need to invest in a full system to improve your home's security, so the below products are also worth considering:
