A solar panel on a security cam is nothing new, but the panel on this one tracks the sun, rotating to gain maximum exposure. If you can mount it where it can harvest a steady supply of sunlight, the Baseus Security S2 Outdoor Camera 4K's tracking solar panel makes it one of the few outdoor cameras that can run truly unattended, capturing crisp 4K-resolution video as a bonus. For many households, outdoor cameras are the front line of home security. The devices watch over driveways, porches, and backyards, catching activity that doorbell cameras often miss.

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.

Your front door is your home's first line of defense. Having a video doorbell mounted next to that door is almost as important as having a deadbolt, because it will not only give your visitors an easy way to let you know they're there, but it will also know when anyone approaches your home–whether or not you're home at the time. In fact, these cameras are so useful you might want to mount one next to every entry point into your home: side entrances, at your garage door, and the door to your backyard, for example. Whether you're waiting for friends to visit, watching for trouble-makers, tracking parcel deliveries, or hiding from that weird neighbor who keeps asking to borrow your lawn mower, the video doorbell is an essential security tool. TechHive's editors and contributors have been testing video doorbells since 2014, and we continuously evaluate the latest devices along with their accompanying apps.

The feature-laden FamiLock Max S3--the first smart lock we've seen with an integrated video screen on its interior escutcheon--works well, but its onboard camera won't make sense in some home environments. As if on steroids, smart locks have been advancing in amazing and surprising ways over the last year, with each few months bringing a new "first" to the market. Eufy's FamiLock S3 Max offers yet another smart lock innovation that would have been unthinkable just weeks ago: It's the first model we've seen that has a built-in, 4-inch video screen on its interior escutcheon, relaying video from a camera mounted on the exterior escutcheon, no secondary device required. It's a neat idea but right off the bat, it's clearly not a lock that's going to make sense for everyone. Like many homeowners, I have a massive window set into the center of my front door, so having a small video screen that displays what is happening on the other side of that door isn't going to do me much good. However, those with fully opaque doors--especially apartment dwellers –might find this a much more compelling proposition than a peephole.

The myQ Outdoor Camera's long cable makes for flexible installation options, but its low video resolution is showing off some dated tech, and you'll need to pay for a subscription to save video at all. The Chamberlain Group-owned operation seems intent not to reinvent the wheel here. Aside from a light cosmetic change to the base, this is very much the same camera as the myQ Indoor Camera and the Garage Camera. This review is part of TechHive's in-depth coverage of the best home security cameras as well as the best smart garage door controllers. The swiveling ball-and-socket base is the main departure from the design of myQ's prior models, and the design change means that the myQ Outdoor Camera must be installed on a wall, though theoretically it could also work on a ceiling in a pinch.

Baseus has announced the launch of its S2 solar-powered security camera, which features solar tracking technology, advanced motion detection, and a wire-free design. The S2 ( 149) builds on the foundation laid by the Baseus S1 Pro, which introduced features like a rotating solar panel and advanced AI motion detection. While the S1 Pro boasted 3K resolution and a dual-lens system with optical zoom, the S2 takes clarity a step further with Ultra 4K resolution, delivering sharper visuals for more detailed monitoring. At the heart of the S2 is its sun-powered tracking system, which rotates the solar panel 40 degrees left and right to maximize sunlight exposure. This feature complements the S1 Pro's solar panel, which could tilt and rotate more dynamically, improving efficiency by 30 percent over static panels.

Today, they watch us as we approach, let the people inside the home know we're coming sooner than our finger can hit the button, and give them a good look at our faces before they open the door. The Guardian's journalism is independent. We will earn a commission if you buy something through an affiliate link. If you haven't already installed one of these handy tools, there's a huge array available. Choosing the best video doorbell can be a bewildering task, with various factors to consider, including how much of your doorstep you want to see or whether you're prepared to pay for a subscription.

Surveillance systems often struggle with managing vast amounts of footage, much of which is irrelevant, leading to inefficient storage and challenges in event retrieval. This paper addresses these issues by proposing an optimized video recording solution focused on activity detection. The proposed approach utilizes a hybrid method that combines motion detection via frame subtraction with object detection using YOLOv9. This strategy specifically targets the recording of scenes involving human or car activity, thereby reducing unnecessary footage and optimizing storage usage. The developed model demonstrates superior performance, achieving precision metrics of 0.855 for car detection and 0.884 for person detection, and reducing the storage requirements by two-thirds compared to traditional surveillance systems that rely solely on motion detection. This significant reduction in storage highlights the effectiveness of the proposed approach in enhancing surveillance system efficiency. Nonetheless, some limitations persist, particularly the occurrence of false positives and false negatives in adverse weather conditions, such as strong winds.

The effectiveness of Ring security cameras and video doorbells is determined by more than their image quality; it's also about how well they detect and respond to motion. Properly configured motion settings can make the difference between a system that enhances your peace of mind and one that overwhelms you with alerts; or worse, fails to notify you of critical events. Ring's motion settings are at the heart of this process, determining when, how, and how often you're notified about activities around your home. Used strategically, they enable you to tailor your security system to your specific needs so that you get the most relevant alerts while minimizing unnecessary disruptions. While the Ring app makes it easy to enable and disable motion detection and alerts on your Ring device, most other motion settings require a little digging to uncover.

Motion artifacts in Magnetic Resonance Imaging (MRI) are one of the frequently occurring artifacts due to patient movements during scanning. Motion is estimated to be present in approximately 30% of clinical MRI scans; however, motion has not been explicitly modeled within deep learning image reconstruction models. Deep learning (DL) algorithms have been demonstrated to be effective for both the image reconstruction task and the motion correction task, but the two tasks are considered separately. The image reconstruction task involves removing undersampling artifacts such as noise and aliasing artifacts, whereas motion correction involves removing artifacts including blurring, ghosting, and ringing. In this work, we propose a novel method to simultaneously accelerate imaging and correct motion. This is achieved by integrating a motion module into the deep learning-based MRI reconstruction process, enabling real-time detection and correction of motion. We model motion as a tightly integrated auxiliary layer in the deep learning model during training, making the deep learning model 'motion-informed'. During inference, image reconstruction is performed from undersampled raw k-space data using a trained motion-informed DL model. Experimental results demonstrate that the proposed motion-informed deep learning image reconstruction network outperformed the conventional image reconstruction network for motion-degraded MRI datasets.
