The current model dates from 2023, but the Octa Core processor is plenty fast enough for consuming Amazon Prime content, which is really the primary reason to buy a Fire tablet. The full HD (1080p) screen won't win any awards, but it's good enough for streaming movies. Fire tablets can do double duty as an Echo speaker, too. Turn on Show Mode (swipe down on the notification overlay and check the Show Mode box) and you can query Alexa to your heart's content.

Contrary to popular belief, most property crimes--including burglaries and package theft--happen during the day, not under cover of darkness. But night still brings unique challenges: fewer people around, limited visibility, and more opportunity for intruders to move unseen. If your security camera can't see clearly after dark, you're missing protection when you might need it most. Night vision lets security cameras capture what the human eye can't see in the dark. Some cameras shine invisible infrared light to illuminate a scene, while others rely on light-sensitive sensors to amplify what little light is already there.

Home security cameras are easy to install, easy to use, and incredibly affordable these days. They let you keep tabs on your home–inside and out–from wherever you have internet access. They can respond to motion, creating a visual record of everything that's happened within their field of view, and high-end models can distinguish between people, pets, and even cars. The latest security cams require minimal installation and offer flexible setups and a range of security features--so many features, in fact, that it can be difficult to decide what you need and which model you should buy. Should you get an outdoor camera with a space-illuminating floodlight and a weatherized shell, an indoor cam with AI-powered pet detection and a motorized lens that patrols the room, or something in between? We've tested dozes of the top home security cameras available in real-world conditions, and we've distilled a list of the very best models. Whether you're looking to check on your kids and pets, or need a full-service sentinel with humans watching for intruders in real time, we'll help find the right security camera for your needs. Easy to set up yet packed with cutting-edge features, the Arlo Pro 5S 2K is the best choice for a battery-powered 2K security camera that can track moving subjects, see in the dark, and connect to speedy 5GHz Wi-Fi networks–everything you need to keep an eye on your homestead.

The Eufy S4 Max NVR is a serious system for users who want smart features without giving up privacy or flexibility. Most home security systems force you to choose between smart features and local control. As its name indicates, this is a PoE (Power over Ethernet), NVR (Network Video Recorder) system with a built-in AI agent that runs on its own local hardware--there's no cloud storage and no subscription fees required to unlock key features. The bundle includes four of Eufy's PoE Cam S4 triple-lens cameras. Each of these has a fixed-position camera with a single wide-angle lens (122-degree field of view) that's fused to the dual-lens, pan/tilt/zoom camera beneath it.

Amazon Prime Day 2025 is fast approaching, and the sale is already underway on some items. To help you find the best early Prime Day deals, we've scoured Amazon for deals on the tech we love.

Security cameras can give you peace of mind by watching things when you're out of the house. They can also help keep tabs on your pets' actions or let you check in on other parts of your property like your backyard. Set them up outdoors or at a window and you can get notifications when someone's delivering a package or heading to your door. Of course, anything that takes footage in and around your home is a privacy risk, so you'll want to look for security cameras with proper privacy features. And if you've already got some smart devices, it's important to know whether your new camera will work with them. Some cameras are practically useless without a subscription, while with others, the subscription is just nice to have. There's a lot to consider -- so we tried out over a dozen well-regarded models, filming our cats, dogs and other household members for weeks to help you pick the best security camera for your home. One of the first things you'll want to consider before buying a security camera is where you intend to put it. Do you want an outdoor or indoor setup, or cameras that can work in both environments?

Amazon Prime Day is usually a great time to pick up things for your home, particularly smart home tech. This year, a bunch of Google's Nest devices have been discounted, with many down to record-low prices. These gadgets are best for anyone who already lives within the Google ecosystem, especially those who already rely on the Google Assistant to help them get things done. You'll find a few Nest security cameras on sale for Prime Day, as well as video doorbells and Wi-Fi systems. If you're looking for even more Prime Day deals, check out Engadget's Prime Day hub where you'll find all of the best tech deals you can get for the shopping event this year.

All you have to do is mount it and connect it to your Wi-Fi network through the Ring app.
