The best home security systems for any budget in 2023

UPDATE: Aug. 17, 2023, 5:00 a.m. EDT This home security guide has been updated with new information and resources. Our overall product recommendations have not been changed.

The height of the COVID-19 pandemic fueled a surge of interest in home security systems as everyone spent more time inside (and dealt with the headache of missing packages), and market research indicates the industry will continue to grow in the coming years. In addition, many Americans are nervous about rising rates of violent crimes and auto thefts, and they're looking for new ways to protect themselves.

But complicated industry jargon, ambiguous pricing, competing technologies, and ongoing news about serious privacy concerns can easily intimidate the average consumer.

So how do you choose the best home security system?

Here's a rundown of everything you need to know when shopping for a security system. (Spoiler: Ring isn't the only company you should avoid.)

What is a home security system, exactly?

A home security system is a group of devices that all work together to protect your home, usually using a combination of visual surveillance, motion detection, audible alarms, and system alerts. These systems may also include home monitoring for a monthly or annual fee.

Traditionally, home security systems were installed by professionals from companies such as ADT or Vivint, then combined with home monitoring. However, the rise of DIY home security systems from companies like SimpliSafe and Ring have drastically changed the options (and prices) available to consumers. DIY home security solutions allow you to install security cameras, motion sensors, and other alarm systems yourself. Often, these smart security systems connect to your home's WiFi, letting you store security camera footage in the cloud or view video remotely in real-time.

What devices are used in home security systems?

The average home security system typically includes a camera or two, motion sensors that can make out infrared energy, a handful of sirens (either built into the sensors and cameras or standalone devices), and a base hub syncing all of the hardware. You'll control the latter manually using a keypad or key fob, or with a companion mobile app.

From there, most home security companies will give you the option of fleshing out your system with à la carte accessories for further protection. Popular add-ons include:

• A glass break sensor that alerts the system when it detects the sound frequencies or vibrations of shattered glass.

• Environmental sensors that can detect water leaks, smoke, and carbon monoxide.

• A panic button that quickly alerts law enforcement in emergency situations.

• Yard signs and stickers that serve as visual (and inexpensive) deterrents to wannabe intruders.

Most home security companies are also in the business of home automation these days, which means you'll be able to control your setup using smart assistants and connect it to other devices like smart locks, lightbulbs, and thermostats. If you want to get really fancy, several brands also offer support for "If This Then That," or IFTTT, a free web-based service that lets you connect and build commands for internet-enabled devices and apps.
