This super-easy-to-set-up Eufy security camera is on sale right now for an amazing 70 on Amazon. That's a whopping 46 percent off and close to the best-ever price we've seen for it lately. The Eufy SoloCam S220 isn't just wireless (for easy installation anywhere), but also has a built-in solar panel that keeps it charged day to day. You never have to worry about taking it down every few months just to charge it back up and re-mount it wherever it goes. A few years ago, I had to set up my own security system for my current home. It was a pain in the neck with all the wires, and it would've been so much easier (and cheaper and faster) if solar-powered cameras like this were as affordable back then as they are now.

Robot vacuums are having a very weird year at CES 2025. We've seen robot vacs that can scoot over stairs and pick up socks. Now, another robot vacuum maker is showing off robot vacuums that can zoom around with air purifiers, tablet stands, security cameras, tabletops and other objects on top. The SwitchBot K20 Pro is a robot vacuum that doubles as a modular platform for other household devices. The company describes it as a "multitasking" household assistant that can perform a bunch of tasks while maybe also cleaning your floor.

TP-Link has made smart home devices before, but it's going all-out for 2021. The router maker has introduced several Kasa-branded gadgets at CES, including a Kasa Smart Doorbell (aka the KD110). The device helps you greet couriers (and spot intruders) with a 1080p camera that uses AI-based person detection. You can subscribe to Kasa Care if you want a rolling 30 days of cloud storage for footage, but you can also use microSD cards up to 128GB if you'd rather store video locally. Security cameras play a large role as well.

Companies that offer surveillance cameras are increasingly implementing software that uses artificial intelligence to identify people based off their face and body type. See how the AI in Briefcam works.

Home security cameras have a couple of ways of maximizing the amount of room real estate they can cover. Ultra-wide angle lenses are the most common solution, but they often cause distortion as they squeeze the image to fit. Cameras with motorized pan-and-tilt features let you sweep the room, but this leaves you turning your back on one part of a room to see what's happening in another. The Guardzilla 360, as its name suggests, pulls off the neat trick of monitoring an entire room all at once. The Guardzilla 360 uses the same pyramid design as the original Guardzilla All-In-One HD Security Camera, but this model is equipped with 1712p HD camera on the top pointing up.
