Home Security Camera Buying Guide

It has never been easier to keep an eye on your home, thanks to a new wave of connected home security cameras. These streaming video cameras connect to your home WiFi network to send alerts, video clips, and live video feeds to your smartphone, allowing you to monitor activity while you’re away.

Your Security Camera Options

Home security cameras are DIY devices, meaning you set up and monitor them yourself rather than hiring a security company to do the work and the watching. While they can save you from installation and monitoring fees, you forgo a 24/7 response team when you do it yourself. You’ll have to decide whether you will feel safer with professional monitoring or self-monitoring through alerts that pop up on your phone. (If you’re interested in a professionally monitored home security system, check out our DIY home security system ratings, which feature many models with optional professional monitoring.) 

Wireless security cameras have become relatively affordable in the past decade, thanks to ever-faster internet, smaller camera sensors, and cheaper WiFi chips. More recently, startups such as Ring and SkyBell leveraged that same technology to create an entirely new product category—the internet-connected video doorbell. These doorbells offer all the features of a wireless security camera while also alerting you if someone rings the doorbell. As such, they do double duty: If you have a video doorbell, you probably don’t also need a wireless security camera covering the front door.

And because most traditional doorbells run on low-voltage wiring, there’s a steady stream of power available for a video doorbell.

While these new breeds of security camera offer greater convenience than ever before, the products are far from perfect. We found that most of the models we tested don’t deliver the high-definition video quality their manufacturers promise under all situations. And many models require you to pay monthly fees for some of the most important features, such as cloud video storage and monitoring zones (the ability to focus on or, alternatively, ignore motion within a designated area of the camera’s field of view).

That’s not to say home security cameras can’t provide peace of mind, by letting you see that your kids arrived home safely from school, or that the dog walker showed up as scheduled, or that a UPS package arrived. And companies keep making these cameras smarter through software updates that add new features, such as person detection and facial recognition.

With so many types of models and features, it can be hard to know what to look for. Here, we break down everything you need to know to find the right security camera to protect your home.

How We Test Home Security Cameras

Our comprehensive testing methodology builds on CR’s expertise in testing cameras, televisions, and other connected devices. We focus our tests on how quickly a camera sends alerts to your smartphone when motion is detected—and for video doorbells, when you can see who pressed the bell—as well as its video quality and smart features. These factors can make or break your experience with wireless security cameras and video doorbells.

For the response-time test, we measure how long it takes for the camera to detect movement occurring in its field of view and send alerts to its smartphone app. For video doorbells, we also time how long it takes for a button press to result in smartphone alert and, subsequently, a live video feed, which is critical if someone is waiting at your front door.

For the video-quality test, we set up a room with multiple resolution charts, everyday objects, and mannequins as stand-ins for people, and evaluate how clear the video is from cameras in good light, low light, and zero light (to test night vision). CR engineers designed this test to expose weak spots in the cameras, whether in their sensor, lens, or software. We also add different levels of backlighting to each lighting scenario. All these tests assess whether you would be able to clearly see people or objects in the frame, such as a potential intruder. The results of these tests appear in an individual video-quality score for each wireless security camera and video doorbell in our ratings.

When it comes to smart features, we assess a wide variety of capabilities depending on the type of home security camera. They may include monitoring zones, person detection, facial recognition, voice control (with Amazon Alexa, Google Assistant, and Apple’s Siri), smartphone alerts, two-way audio, scheduling, and geofencing (which turns alerts on and off depending on whether the device reads that your smartphone and, presumably, you are nearby). All these features factor into our unique Smart IQ score for smart home devices, allowing you to see which cameras are smarter than the competition.

Due to continued hacks of wireless security cameras and the growing privacy concerns around video doorbells that record public areas (such as streets and sidewalks), we test all these cameras for data privacy and security. In the tests, we evaluate each company or service provider’s public documentation, such as privacy policies and terms of service, to see what claims the manufacturer makes about the way it handles your data. The tests include inspection of the user interface and network traffic from each camera and its companion smartphone app to make sure it’s using encryption, adhering to manufacturer policies, and not sharing your data with irrelevant third parties.

Finally, our test engineers take the results of these individual tests and use them to calculate our Overall Scores for both camera types.

Types of Home Security Cameras

There are two main types of home security cameras: wireless security cameras and video doorbells. Here are the differences.

A wireless security camera.

Wireless Security Cameras

These unobtrusive security cameras connect to your home network and send alerts and videos to your smartphone. Some models need to be plugged into an outlet, and others run on rechargeable-battery power, making them truly wireless. Some cameras can store video clips locally on a memory card, but most don’t have that feature, forcing you to store them in the cloud—and allowing manufacturers to charge you a recurring fee.

Pros: They can be placed just about anywhere inside your home. Weatherproof models can be placed outdoors. You can check on your home and receive smartphone alerts from anywhere with cell service or WiFi.

Cons: Cloud storage fees can add up over time. Some smart features require paying a monthly fee.

Video Doorbells

Video doorbells are really just security cameras that happen to be built into a doorbell. Most use low-voltage wiring from an existing doorbell for power, though a few models can run on batteries, which is handy if you don’t have a wired doorbell in place. Battery-powered models require periodic recharging or battery replacement. These cameras send alerts and videos to your smartphone when they detect motion or when someone rings the doorbell. All video doorbells also feature two-way audio, so you can talk to whoever is ringing. Some models come with a memory-card slot for storing video clips locally, but most store video clips in the cloud, which usually requires a monthly fee for long-term storage.

Pros: Most use doorbell wiring for power, negating the need to run a separate power line. You can answer your doorbell even when you’re not home.

Cons: They won’t work with an existing wireless doorbell chime. Their connection to your WiFi may be affected by being outside the thick walls of your home. Cloud storage fees can add up. Some smart features require paying a monthly fee.

How to Choose a Home Security Camera

1. Choose Your Camera Type
The type of camera you’ll need depends on where you want to place it. If you want one inside your home, there are many home security camera options. If you want one outside your home, you’ll need to decide whether you want a wireless security camera or a video doorbell.

For monitoring a front or back door, consider using a video doorbell because it can be powered through your doorbell wiring. If you want to monitor another area of your property, you’re better off with a wireless security camera. Keep in mind that while all video doorbells are designed to survive the elements, not all wireless security cameras are weatherproof. So be sure to check the specs of a camera you’re considering if you want to put it outside.

2. Pick Your Power Source
Battery-powered wireless security cameras and video doorbells offer the most flexibility in terms of placement in and around your home. Depending on the camera and how heavily it’s used, you’ll need to recharge it anywhere from weekly to once every few months to once or twice a year. Hardwired cameras and doorbells neatly sidestep the recharging problem but may limit your placement options, unless you’re willing to run an extension cord or hire an electrician.

Keep in mind that the power source you use could limit the number of models you can choose from. This is especially true of video doorbells because there aren’t many battery-powered models on the market.

3. Compare Cloud Storage Plans
Before you pick the camera or doorbell you want, be sure to find out how much free cloud storage it comes with and how much additional storage costs. Most manufacturers opt for cloud storage—where the footage is remotely stored on a server—instead of memory cards because the video files are large. Without cloud storage, if you miss an alert for a potential intruder, you’ll have no idea whether someone tried to break in. Many of these cameras also won’t let you download clips to send to authorities unless you pay up.

The amount of free online storage and cost of storage plans can vary drastically by manufacturer and model. For example, the Arlo Pro 2 security camera comes with seven days of free cloud storage, which stores the most recent seven days of motion-triggered video clips, but newer Arlo cameras come with no free storage at all. Arlo charges $3 to $5 per month for 30 days of motion-triggered storage for one camera, depending on the model. (Storage plans for multiple cameras or 24/7 recording cost even more.) Ring video doorbells offer no free storage, but Ring charges only $3 per month (or $30 per year) for one camera for 60 days of storage.

Keep in mind, most of these plans store only video clips triggered by motion, not continuous video feeds. However, some brands, such as Arlo and Google Nest, offer continuous video storage plans.

4. Consider Your Privacy
While these cameras provide peace of mind, it’s worth remembering that to do that they provide a view into your home and connect to the internet. If you can watch your home from your phone, it may be possible for someone else to take a peek, too. The manufacturer also may have access to the video.

“There have been cases of companies deploying these with weak security that can be circumvented,” says Justin Brookman, director of privacy and technology policy at Consumer Reports. “Don’t use default credentials. Make sure you set up your own unique username and difficult-to-guess password.” Read our article on creating strong passwords to make sure yours are as hackproof as they can be.

More and more cameras are offering two-factor authentication, an additional layer of security that sends you a one-time-use passcode via a text message, a phone call, an email, or an authentication app. You input the passcode in addition to your username and password when you log in. That way, if a hacker cracks your password, they won’t be able to access your camera unless they also gain access to your one-time code. If your camera offers this, be sure to activate it. You can also find more advice in our article on preventing security cameras from being hacked.

These security concerns don’t mean you shouldn’t buy a home security camera, but if privacy is something you’re worried about, you may want to keep these devices out of bedrooms.

To help you purchase a camera that respects your privacy, we rate each model for data privacy. You can see how the privacy of each camera measures up in our home security camera ratings.
