DJI just announced the dual-camera Air 3S drone and theres some all-new cutting-edge tech hiding in the nose. A LiDAR sensor is there to provide extra crash protection at night, a time thats often dangerous for drones. The Air 3S also has a new main camera with a larger sensor better suited for capturing video in low-light. And it now comes with the companys ActiveTrack 360, which it first introduced in the Mini 4 Pro, allowing the device to zoom all around your subject while tracking and filming them. There are a bunch of other little improvements, from storage to the new panoramic photo mode, all at the same $1,099 price as the Air 3 was at launch. To see if it lives up to DJIs hype, I tested all of its new capabilities, especially the new night-flying obstacle avoidance. Design The Air 3S looks a lot like the Air 3 and weighs just 0.1 ounces more at 1.6 pounds. Since its over 250 grams, you need a permit to fly it in the US and elsewhere. Unlike the Avata 2 or Neo, the Air 3S is obviously not suited to fly around people, but DJI does offer propeller guards for a bit of extra safety. The Air 3S camera module is larger as well because it holds a new 50-megapixel 1-inch sensor camera with a 24mm f/1.8 lens, up from from the previous models 1/1.3-inch sensor. This setup supports 4K recording up to 120 fps and 1080p at 240 fps, along with D-LogM to improve dynamic range. DJI also boosted the maximum ISO to 12,800 for improved light sensitivity. The secondary 70mm (3x) zoom camera is unchanged with a 1/1.3-inch sensor, and it supports the same video specs and color modes as the primary. The Air 3S is DJIs latest drone with its ActiveTrack 360 system. Once you start tracking a subject, you can change the camera angle using an onscreen control wheel. The drone will then figure out the best way to change positions while also avoiding obstacles. It does so using six vision (camera) sensors, two downward facing infrared time-of-flight sensors and the new LiDAR. Another key change on the Air 3S is its 42GB of internal storage, up from 8GB on the Air 3 something thatll be handy if you forget a microSD card or fill one quickly. You can transfer files to your PC either by a Wi-Fi connection or the drones USB-C port. The wired method now works even if the drone is turned off. Steve Dent for Engadget The Air 3S can hit up to 45 mph in sport mode. Thats fast and theres no obstacle detection with this setting, so you need to know what youre doing. In normal mode, which does support obstacle tracking, speeds drop down to 23 mph. You get about 12.5 miles of range in the US via DJIs latest O4 transmission system, or half that in Europe. One small change is that the Air 3S now transmits 10-bit 1080p 60p video rather than 8-bit as before, improving remote video capture quality. Battery life on the Air 3S is excellent at 45 minutes, which equates to about 38 minutes under working conditions. With the optional Fly More kit that includes three batteries and a charging hub, pilots should be able to fly most of the day. Like the Mini 4 Pro, the charging hub supports power accumulation, so you can transfer energy from the weakest batteries to the strongest for longer flights. Finally, the Air 3S appears to have the same propeller system as the Air 3 and emits about the same amount of noise. Its pretty quiet for such a large drone, and once it gets up to around 150 feet, you can barely hear it. Performance Steve Dent for Engadget I tested the ActiveTrack 360 function while walking, biking and driving a car to see how it worked at various speeds. When tracking my car at around 20 to 25 mph, it stayed locked on while easily avoiding trees and power lines. I found a bike trail among some widely spaced trees and another with denser foliage. In the first section, the drone weaved smoothly around obstacles while keeping the bike in frame. After a few minutes, I was confident it wouldnt crash and was able to focus on creating some cool shots. The drone occasionally hesitated when it encountered obstacles, which spoiled some footage. However, it never crashed or lost track of the bike. Things werent quite as easy on the dense brush trail. When I changed the camera angle, the drone would occasionally pick a bad route, get hemmed in by branches and stop. A few times the propellers knicked leaves or branches, throwing the drone off keel. It never crashed or took any damage, but I replaced the propellers out of an abundance of caution. Steve Dent for Engadget That experience taught me that the Air 3Ss sensors can miss small obstacles, so its wise to stay away from those situations and use propeller guards if you cant avoid them. You also need to make sure the drone has enough room to maneuver when using ActiveTrack 360 to change camera angles. Later, I took the Air 3S out at night to test the LiDAR, flying it up around trees and next to buildings. Previously, this would have been vry risky, but the Air 3S successfully detected and avoided all obstacles. This new low-light capability will be especially helpful when you need to bring the drone home in the dark. Keep in mind that the LiDAR only works in the forward direction, so avoid going backwards or sideways at night. Video quality Steve Dent for Engadget To test the video quality, I shot aerials with the Air 3S, at dawn, in the daylight and at night. With the larger 1-inch sensor, 4K video is more detailed than ever and the camera produces vibrant, accurate colors and nice skin tones. It also does a great job in variable light conditions when using the DLogM setting. That came in handy when I was biking in the forest with a mixture of dappled sunlight and shadows. The 4K 120 fps setting is nice for creating dramatic shots with moving subjects, and theres no discernible loss in quality compared to the 30p or 60p modes. The Air 3S promises up to 14 stops of dynamic range, DJI promises, matching high-end mirrorless cameras. Thats impressive for a drone. If things are too bright, DJI includes an ND filter kit to reduce brightness and avoid high shutter speeds that can make video look choppy. Steve Dent for Engadget The secondary 70mm-equivalent telephoto camera with a 1/1.3-inch sensor is the same as before and similar to the one on the Mini 4 Pro. To that end, its not as sharp as the main camera and not as good in low light. However, DJI tuned it to closely match the main sensor, so its now easier to combine shots from each. This camera also supports D-LogM video to boost dynamic range. The 3-axis mechanical gimbal allows for incredibly smooth footage, which is a hallmark of DJI drones. And if you need to shoot photos, the Air 3S produces sharp and color accurate RAW images that can be manipulated in post for great results. Wrap-up Steve Dent for Engadget The $1,099 Air 3S is DJIs most technologically advanced drone yet thanks to the LiDAR sensor, updated 1-inch camera and ActiveTrack 360 subject tracking. The obstacle detection is a strong point, and though the drone isnt invulnerable, I felt very safe flying it once I figured out its limitations. As usual, DJIs main competition is itself. The Mini 4 Pro is priced at $759 but lacks rear sensors and has inferior image quality. The triple-camera Mavic 3 Pro has a larger sensor that produces a slightly more cinematic image, but it costs $2,199. And of course, you can also look at DJI's Air 3, which has now dropped a bit in price. The only real non-DJI alternative is the $2,099 Autel Evo II Pro 6K (kit), which has just a single 1-inch camera and is also a lot more expensive.  I think the Air 3S is a better choice than the Mavic 3 Pro for most video creators, because video quality is outstanding and it has superior obstacle detection. If I were a content creator looking for a high-end drone right now, the Air 3S is the one Id buy.This article originally appeared on Engadget at https://www.engadget.com/cameras/dji-air-3s-review-lidar-and-improved-image-quality-make-for-a-nearly-faultless-drone-130002876.html?src=rss

China has denied allegations by the US government and Microsoft that a state-sponsored hacking group called the Volt Typhoon has infiltrated US critical infrastructure, according to Bloomberg. The country's National Computer Virus Emergency Response Center called the claims a "political farce" orchestrated by US officials in a new report. It also reportedly cited more than 50 cybersecurity experts who agreed with the agency that there's no sufficient evidence linking Volt Typhoon to the Chinese government.  Moreover, the Chinese agency said that it's the US that uses "cyber warfare forces" to penetrate networks and conduct intelligence gathering. It even accused the US of using a tool called "Marble" that can insert code strings in the Chinese and Russian languages to frame China and Russia for its activities. Microsoft and the National Security Agency (NSA) first reported about Volt Typhoon back in May 2023. They said that the group installed surveillance malware in "critical" systems on the island of Guam and other parts of the US and has had access to those systems for at least the past five years. In February this year, the Cybersecurity and Infrastructure Security Agency (CISA), the NSA and the FBI issued an advisory warning critical infrastructure organizations that state-sponsored cyber actors from China "are seeking to pre-position themselves on IT networks for disruptive or destructive cyberattacks." The US agencies said Volt Typhoon had infiltrated the US Department of Energy, US Environmental Protection Agency, as well as various government agencies in Australia, the UK, Canada and New Zealand. Volt Typhoon doesn't act like other cyberattackers and espionage groups do. It hasn't used the malware it installed to attack any of its targets at least not yet. The group is "pre-positioning" itself so that it can disrupt critical infrastructure functions when it wants to, which the US government believes is "in the event of potential geopolitical tensions and/or military conflicts" with the United States.This article originally appeared on Engadget at https://www.engadget.com/cybersecurity/china-calls-allegations-that-it-infiltrated-us-critical-infrastructure-a-political-farce-120023769.html?src=rss

Google said it will partner with the startup Kairos Power to build seven small nuclear reactors in the US. The deal aims to farm 500 megawatts of nuclear power from the small modular reactors (SMRs) by the decades end. The first is expected to be up and running by 2030, with the rest arriving through 2035. Its the first-ever corporate deal to buy nuclear power from SMRs. Small modular reactors are smaller than existing reactors. Their components are built inside a factory rather than onsite, which can help lower construction costs. Its not a dead cert: Kairos will need the US Nuclear Regulatory Commission to approve the plans. Continue reading.
