Best indoor home security camera
The Arlo Pro was already a great security camera. The second-generation model is even stronger, adding even higher resolution and better motion detection to its long list of features that already includes the flexibility of operating on either AC or battery power (and there’s an optional solar panel that enables the camera to operate completely free of wires).
You don’t need to sign up for Amazon Key—the service that allows couriers to open your door and deliver packages inside your home—to benefit from this excellent and very inexpensive home security camera. A long list of features (including 1080p video resolution, motion detection, and two-way audio) and tight integration with Amazon’s Echo product line are just a few of this camera’s attractions. We like it a lot.
Best outdoor home security camera
The Nest Cam IQ Outdoor is the most sophisticated outdoor home security camera on the market. Equipped with a 4K image sensor, high dynamic range, and person detection, this camera zooms in on humans in its field of view and follow that person around the room, capturing their face in great detail.
Best security camera/outdoor lighting combo
There’s a lot to like about the Maximus Camera Floodlight, starting with its camera’s crisp, clear 1080p video. Its dual articulating LED floodlights cover a very wide area, and you can dim them via its app if you want mood lighting on your deck or patio for a party.
Other features that differentiate the Maximus from its better-known competitor—the Ring Floodlight Cam—include pre-recorded messages that can be triggered by the camera’s motion detector (causing the intruder to instinctively look up at the camera) and a subscription service that’s actually optional: You can look back only two hours and you’re limited to three downloads per month if you don’t subscribe, where Ring gives you only real-time viewing and no downloads if you don’t pay.
The Ring Spotlight Cam is a great choice for folks who don’t want to replace their existing outdoor lighting with a camera/light combo. You don’t need to deal with bare electrical wires, you just plug it into a nearby outdoor socket. And if you don’t have one of those, you can buy a battery-operated model and trickle-charge it with a solar panel.

What to look for when shopping
Most home security cameras perform the same basic functions—they detect an event, record the event, and send you an alert—but they don’t all perform them the same way. And some cameras have special features that go beyond those basics. Here are some common features you’ll encounter while shopping and why they’re important (we’ve listed them in alphabetical order). In each of the reviews that follow this buyers’ guide, we’ll discuss how each camera delivers on these features.
Alerts: Home security cameras push notifications to your smartphone when they detect events. Without watching the live feed all day, this is the only way to keep tabs on your home in relative real time. Depending on the camera, it may send text alerts when it detects motion, âm thanh, a face (known or unrecognized), or all three. Some can send alerts to multiple people, usually anyone else in the household using that product’s app; others will send emails in addition to text messages as a failsafe in the event you can’t access your mobile device.
Battery backup: Power outages happen, and clever burglars cut electricity before breaking into your home. When that happens, your camera goes dark and, if there’s a crime taking place, you lose all forensic evidence. Vì lý do này, some cameras can also run for a short time on battery power. It’s a feature worth looking for.
Cloud recording: Many manufacturers offer cloud storage plans with their camera. With one of these, your recorded video is sent to a remote server and stored for a predetermined time— usually anywhere from 24 hours to a week—and then deleted to make space for new videos. Though sometimes free, these cloud plans usually require a monthly subscription, but are worth it both for their convenience and if you want a surveillance record during a vacation or other extended time away from home.
Environmental monitoring: This is the feature that sets all-in-one home monitors apart from strictly-security cameras. Though the home “vitals” that these units track vary by model—we’ve seen everything from motion to luminosity included in home health profiles—three tend to be ubiquitous:
- Temperature monitors for spikes and dips in indoor temperature and alerts you when it falls outside a range you define.
- Humidity tracks relative humidity inside your home. Humidity outside optimal levels—usually defined as between 30 và 50 percent—can contribute to problems such as static electricity, sinus irritation, and mold growth.
- Air quality tracks pollutants ranging from cooking odors to carbon monoxide. Tuy nhiên, most monitors don’t identify the pollutant in their alerts, merely warning that the air quality is “abnormal.” Because of that, this feature should not be considered a substitute for potentially life-saving devices like smoke and carbon monoxide detectors.
Facial recognition: A few newer cameras are experimenting with facial recognition. This feature could more accurately be called “facial identification,” as in practice it’s much better at distinguishing a face from, Nói, a lamp, than it is at actually distinguishing between one person’s face from another’s. If you opt for a camera with this feature, know that it typically learns faces through increasing exposure to them, so be prepared to spend a lot of time in front of the lens.
Local storage: Some cameras include memory-card slots in lieu of, or in addition to, lưu trữ đám mây, so you can store video right on the device. It’s an attractive feature as it can eliminate the cost of monthly storage fees. The downside (if there isn’t a cloud backup) is that if a crook steals your camera, he takes your forensic evidence with it.
Mobile app: Most of today’s home security camera’s are accessed primarily through a smartphone/tablet app. In addition to offering you a reliable way to view the camera’s live feed, it should offer plenty of options for customizing the way the camera performs. The ability to customize notifications, adjust motion and sound detection sensitivity, and set detection areas are some of the key features to look for. The app should also be intuitive and easy to master.
Motion detection: Assuming you’re monitoring your home when it’s empty, motion detection is one of the most desirable features in a security camera. Built-in sensors pick up movement within the camera’s field of view and trigger video recording.
You’ll find an in-depth explanation of how motion detection works in this article.
Because these sensors are sensitive to bất kì movement—event a shift in lighting or leaves blowing outside a window—it’s important the camera system also offer the ability to narrow the range of detection, adjust the sensor’s sensitivity, or otherwise customize this feature to cut down on false alerts.
Night vision: Most break-ins occur after dark, so this feature is nearly as important as motion detection. Về mặt kỹ thuật, most home security cameras support infrared LED illumination, versus true night vision based on image intensification or thermal vision. Be that as it may, some camera’s will switch to night vision automatically in low-light conditions, while others allow you to customize when and how it should be activated.
Pan/Tilt/Swivel: Most security cameras—including all the ones in this guide—can be manually tilted and swiveled to focus on a certain viewing area, but this is a purely set-it-and-forget it feature. A true pan/tilt camera is equipped with a motor so that you can move its lens—or even follow a moving object if you’re watching a live feed—using its app or browser-based app.
Độ phân giải: No amount of security video will help you if it’s blurry, jittery, or otherwise distorted. Look for a camera that offers the highest possible resolution. Most currently offer 720p (often referred to as “high definition” or HD), but some newer cameras are coming out with 1080p (often referred to as “full HD”). Keep in mind higher-res cameras use more Internet and Wi-Fi bandwidth and battery life. Many cameras also offer a software zoom feature (which is not the same thing as having a physical zoom lens).
Scheduling: Scheduling features allow you to tell the camera to turn on and off, detect motion, and/or send alerts at specified times. This is useful when you, Nói, only want to be notified when your kids get home from school or just want to monitor your home when you’re away. It also reduces the amount of false alerts.
Security: Đã có plenty of headlines about hackers compromising home cameras, baby monitors, and other Wi-Fi devices to spy on people, so be sure to check what steps has each manufacturer taken to eliminate this problem. Look for a camera that supports up-to-date wireless security protocols, such as WPA2, and make sure it encrypts Internet transmission of your your user name, your password, and the live feeds. Never install a security camera (or a router or any other device on your home network) without changing its default user ID and password.
Smart device integration: If you have a home full of smart devices, consider looking for a security camera or an all-in-one home monitor that includes a Z-Wave, ZigBee, or—eventually a Thread—radio that can connect them. Support for an automation service such as IFTTT or Stringify is also useful. This allows the camera or monitor to react to various scenarios, such as taking a picture when your Nest Protect detects smoke, or telling your Philips Hue smart bulb to turn on when unexpected sounds are detected.
Two-way audio: While the idea of a security camera implies eyes-on monitoring, the ability to also Nghe what’s going on gives you a more complete picture of what’s happening on the home front when you’re away. It can also alert you to something occurring out of the camera’s field of vision. This feature can also allow you to speak through the camera, a great tool for remotely commanding an unruly pet or startling an intruder in the act, but be aware that you might need to plug in a powered speaker for this feature to work.
Góc nhìn: The camera’s field of view determines how much it can see. As you’re probably monitoring a single room, you want a wideviewing angle. Most current cameras fall in the 130-degree range. These wide angles can sometimes cause image distortion at the edges in the form of a fisheye effect, particularly when used in smaller rooms, but it’s not like you’re going to use a security to capture snapshots for your photo album.
Web client: Many cameras can be accessed through a web portal as well. This is useful for times when you don’t have access to your mobile device or a wireless connection. The web app should closely mirror its mobile counterpart, so you don’t need to learn a whole new set of controls.
Wireless range: One of the benefits wireless cameras offer is the ability to move them around your home. Lý tưởng nhất, your home security camera should be able to maintain a Wi-Fi connection no matter how far you move it from your router, even in a large home. Some cameras come with an ethernet port as well, so you have the option of hardwiring it to your local network. A camera that supports power-over-ethernet (PoE) eliminates the need for an AC adapter and relies on just one cable (but your router or switch will cũng thế need to support PoE. Another alternative would be to use a PoE injector.)
