A home security system is a collection of electronic hardware that is connected by software and managed by a central control panel or app.
The components, which can include door/window sensors, motion sensors, cameras, smoke detectors, glass-break sensors, panic buttons and more, work together to keep you and your home safe.
What is the best home security system?
Protecting your home or apartment from intruders and hazards doesn’t have to be complicated or break the bank. The best home security systems are customizable, affordable and have a variety of features that can make it easier to keep an eye on your loved ones and possessions.
Traditional alarm systems require professional installation and multiyear contracts, but many modern kits can be self-installed, self-monitored and integrate smoothly with smart home technology.
How we found the best home security systems
We identified the largest home security providers by market share and search volume, and then we personally obtained equipment from the providers. We tested and ran the systems through a comprehensive rubric that evaluates their pricing, video features, monitoring, privacy records and customer reviews. We included the top six providers in this roundup; there were several other providers that did not score high enough to be included.
1. Best overall: SimpliSafe
SimpliSafe offers seven customizable home security system packages. We think the setup is straightforward, and we like the system's sleek design and user-friendly app. There are six monitoring options, ranging from free to $79.99 a month, which you can pay for monthly and cancel anytime without entering a long-term contract.

In fact, Abode is compatible with the widest range of smart home products of any provider we tested, including Amazon Echo, Google Home and Apple HomeKit. It offers three base security alarm bundles with different hub models.

4. Best multifunction sensors: Arlo
Arlo is a budget-priced home security provider that offers self-installed home security alarm systems, cameras and doorbells. Its multifunctional sensors can perform eight different types of detection: motion, open/close, water leaks, freezing, tilting, light and listening for sounds from smoke alarms or carbon monoxide alarms. The company also offers several reasonably priced self- and pro-monitoring plans, but you can still use the alarm system’s basic features without paying for a plan.

ADT owns six U.S.-based professional monitoring centers, leading to fast alarm response times. We think the packages are expensive compared to other providers, especially for self-setup packages and basic equipment. But the professional monitoring is tried-and-true. ADT alarm systems integrate with some Nest cameras (mostly newer models) but not all: they won’t connect with the Google Nest Cam Indoor or Outdoor, the Google Nest Hello, or Nest Cam IQ cameras.

Vivint isn't a DIY option; it must be professionally installed and hardwired into the house. Our three-hour professional installation was time-consuming but not difficult or stressful. However, Vivint is the most expensive home security system we’ve reviewed. You can control the system via the smart hub, the keypad or the Vivint mobile app. It also offers smart lights, speakers and thermostats that integrate with Google Home, Nest and Amazon Echo.

Two other things to consider when choosing a home security system
1. Whether you want professional monitoring or self-monitoring
You can choose to have your home security system professionally monitored, or you can respond to alerts yourself. Some providers, such as Vivint, only let you use professional monitoring with their equipment, but others offer both options.
Professional monitoring comes with additional fees: typically around $20 to $50 per month. However, the benefits can be worth the price in an emergency.
When an event triggers your alarm, your provider’s call center is instantly notified, and a representative calls you to check in. If you don’t respond, they contact emergency or police services.
Some providers, such as SimpliSafe, offer the option to let a representative access your camera footage to investigate what triggered the alarm before calling authorities.
If you opt for self-monitoring, you’ll need to respond to the phone alerts your alarm system sends you and decide what steps to take.
Some providers, such as Ring, offer professional monitoring without a contract, so you can purchase temporary alarm monitoring during a vacation, for example.
2. Whether you want smart home integration
Smart home devices let you control your home’s temperature, lighting, music and more from your phone, computer or tablet.
Many home security systems also integrate with existing WiFi-connected smart home networks, such as Google Home and Alexa, to give you the ability to activate and disarm your alarm system — and check your cameras — from your personal devices too.
If you already use a specific smart home network, you may want to choose a security system that integrates with that network. Abode, for example, integrates with a wider variety of smart home systems, while Google Nest is best matched with other Google Home products.
