Home security has a new benchmark for smart surveillance. Meet the new eufyCam S4: a cutting-edge hybrid security camera that redefines what’s possible in smart home surveillance. This camera is built for today’s evolving security needs. The eufyCam S4 blends a fixed 4K bullet lens with a powerful 2K dual-lens PTZ (pan-tilt-zoom) system to give you both the wide-angle perspective and the zoomed-in detail, all in one seamless experience.
The bullet lens is like your constant guardian. It can monitor key areas like driveways and front doors with clarity that stretches up to 29 feet. Meanwhile, the PTZ camera is always ready to track, tilt, and zoom with AI precision, scanning broader zones and keeping tabs on what matters most.
Want uninterrupted security? The detachable solar panel has you covered and it’s eufy’s most efficient yet. You can fully charge the camera with just an hour of direct sun. Built with edge-sealed durability and ETFE film for weather resistance, it’s made for real-world reliability.
And if someone unwelcome shows up? The S4 jumps into action with dual motion detection (radar + PIR) and filters out the noise and homes in on real threats. Red and blue warning lights flash, and a 105dB siren roars into action. It’s an instant, unmistakable deterrent.
At the heart of it all is eufy’s Local AI Agent, powered by the world’s first Qualcomm 4nm AI chip. This system is a powerhouse. It detects, analyzes, and responds to more than 100 real-world risks, including loitering, package theft, fire hazards, and wild animals. It thinks, adapts, and acts.
Here’s how it works: When the bullet camera spots something unusual, the PTZ unit jumps into action by locking on and tracking targets with AI Tracking 2.0. Whether it’s a single person walking across your yard or a group moving down the street, the camera intelligently auto-frames and adjusts, zooming in up to 50 meters or pulling back to capture the whole scene.
This level of intelligence is thanks to the AI Core, which enables large-model processing directly on-device. With both a Fast Path for immediate responses and a Deep Path for complex reasoning, your eufyCam S4 balances speed and smarts like never before. Best of all? Everything is stored locally, so your data stays private.
A phone thermal camera is one of those tools you don’t think you need until the first time it saves you from an expensive problem, and the Thermal Master P3 just got easier to try. For Halloween, it’s discounted with the code THERMCAM10, a 10% cut that works out to $107 off the total. It’s also fresh off a win at the 2026 Tom’s Guide AI Awards for best phone thermal camera, which is the kind of third-party nod that separates a serious tool from the cheap clip-on sensors that flood this category.
Imagine you’re eight reps into a set of goblet squats in your living room. Your legs start to burn, your core is braced, and your focus remains sharply on finishing the set. But as fatigue sets in, an age-old uncertainty creeps in: Are my hips dropping below parallel, or am I cutting depth short? Is my lower back rounding under load? Am I doing this right?
For much of the past decade, mainstream consumer fitness technology has focused on quantification—tracking metrics such as steps, heart rate, workout duration, and calorie estimates. Those metrics can be useful for understanding activity and exertion, but they reveal far less about how a movement was actually performed: whether form changed as fatigue set in, whether squat depth shortened, or whether repeated movements stayed consistent from one rep to the next.
A dash cam has a fairly uneventful life once it reaches a car. It sits behind the windshield, records the road ahead and, ideally, goes unnoticed until the moment its footage is needed. Getting it ready for that job can be considerably less quiet.
Inside Wolfbox’s Central Laboratory, cameras and other automotive products are exposed to extreme temperatures, vibration, mechanical shock, water and prolonged operation. Known for its off-road dash cams and automotive electronics, Wolfbox uses the facility to recreate the difficult conditions its products may encounter before they reach drivers. The idea is simple enough. If a product is expected to work when conditions are difficult, those conditions need to be recreated before a driver encounters them.
