History

Founding and early development

YI Technology was established on February 1, 2014, in , , by Shengwei () Da, who served as co-founder and CEO. As an initial spin-off brand within Xiaomi's ecosystem, the company focused on developing affordable imaging and video technologies to make high-quality action cameras accessible to a broader consumer base, leveraging Xiaomi's robust for efficient production and rapid market introduction. The firm's inaugural product, the YI Action Camera, launched in March 2015 under the Yi branding, featured video recording at 60 frames per second along with a 16-megapixel R sensor, establishing YI as a key player in the sector by offering premium features at a budget price of approximately $64. This device targeted the growing demand for portable video solutions, directly competing with higher-priced options like the Hero series. Early expansion was supported by distribution through Xiaomi's Mi Store and channels, which facilitated strong initial sales in and enabled international availability, including shipments to the and other countries by December 2015. By mid-2016, YI had sold over 1.5 million action cameras, underscoring the effectiveness of its Xiaomi-backed entry strategy.

Key milestones and expansions

In October 2016, YI Technology officially split from Xiaomi to operate as an independent entity, dropping the "Xiaomi Yi" branding while maintaining Xiaomi as an investor and allowing for ongoing collaborative elements in product development and distribution. Following this independence, YI introduced the YI 4K Action Camera in July 2016, marking a significant advancement in its action camera lineup with support for 4K video recording at 30 frames per second, which positioned the company as a competitive alternative in the consumer imaging market. In 2016, YI expanded into professional imaging with the launch of the YI M1 Mirrorless Camera, a Micro Four Thirds system camera featuring a 20-megapixel Sony IMX269 sensor, 4K video capabilities, and interchangeable lenses, aimed at photographers seeking affordable entry into mirrorless photography. To diversify beyond action cameras, launched the sub-brand in 2018, focusing on smart home security products such as the Indoor Camera, which emphasized user-friendly design, AI-driven features, and integration with home ecosystems to address growing demand in the security sector. 's early international expansion included entry into European markets, announced on September 1, 2016, with product showcases at the IFA trade fair in , building on prior U.S. launches to establish a broader global presence for its action and home cameras. Concurrently, pursued partnerships in technology, collaborating with and in May 2016 to develop affordable and high-end 360-degree camera rigs under Google's program, followed by the January 2018 release of the Horizon VR180 camera in partnership with Google's team to support stereoscopic content creation.

Recent developments

In the period from 2019 onward, YI Technology shifted its strategic focus away from action camera development toward enhancing its security and smart home ecosystem. In October 2019, the company announced a pause in active development for all YI Action Cam products and the associated YI Action App, citing resource reallocation without specifying a resumption timeline. As of 2025, no major new launches in imaging , such as action cameras or mirrorless models, have occurred, reflecting a sustained emphasis on for existing devices rather than in this segment. This pivot has centered on solutions, particularly under the sub-brand, which complements YI's broader portfolio for home monitoring. A notable release in this area was the YI Dome Guard 2K camera in January 2024, designed to provide 360-degree panoramic views with AI-powered to distinguish between people, vehicles, and animals, thereby improving accuracy for indoor . The brand, introduced as an extension of YI's offerings, has facilitated this growth by integrating advanced features like infrared night vision and two-way audio into affordable devices. By 2025, YI Technology's user base exceeded 20 million globally, driven largely by the adoption of smart home applications such as YI Home and Kami Home, which offer remote access and activity notifications. These apps have incorporated trial features for detection, including person and pet recognition, to enhance without requiring premium subscriptions initially. Support for legacy products has continued through periodic updates, ensuring compatibility and basic functionality for older hardware. For instance, earlier updates to the YI M1 mirrorless camera, released around 2017, significantly improved speed by up to 300% and added RAW+JPEG shooting options, though no substantial enhancements have followed since. This approach underscores YI's commitment to maintaining an installed base amid the broader transition to cloud-based security services.

Products

Action cameras and imaging devices

YI Technology entered the action camera market in 2014 with the launch of the , a compact device designed for sports and outdoor activities. Featuring a 16-megapixel R sensor and a 155-degree wide-angle f/2.8 lens, it supported video recording at 60 frames per second () and at 120 , enabling smooth capture of fast-moving scenes. Weighing just 72 grams and measuring 60 x 42 x 21 mm, its lightweight, pocket-sized design facilitated easy mounting for point-of-view () videography during travel, underwater adventures (with a waterproof case up to 40 meters), and group or solo photography, complemented by built-in , connectivity, and accessories like an expandable selfie-stick and . In 2016, YI advanced its lineup with the YI 4K Action Camera, emphasizing higher resolution and enhanced usability for dynamic imaging. This model introduced ultra-high-definition (UHD) video at 30 , alongside 2.7K at 60 , at 120 , and at 240 , powered by a 12-megapixel IMX377 and an Ambarella A9SE75 .

Other and discontinued offerings

YI Technology ventured into the drone market with the Erida, a tricopter announced in August 2016 and unveiled at the InterDrone conference in . Featuring a full carbon frame, the Erida was marketed as the world's first mainstream drone of its kind, capable of reaching speeds up to 75 miles per hour (120 km/h) and providing up to 40 minutes of flight time. It integrated a detachable YI 4K Action Camera on a three-axis motorized gimbal for stabilized 4K video recording at 60 frames per second, targeting aerial videography enthusiasts. Despite initial hype as a competitor to products like the GoPro Karma, the Erida saw limited production and was quietly discontinued, with no new units available on official channels and support fading by the late 2010s as YI shifted priorities. In 2018, YI introduced the Horizon VR180 Camera in collaboration with Google's virtual reality team, aiming to simplify immersive through the VR180 . This compact, point-and-shoot device captured stereoscopic video at 5.7K resolution and stills, enabling 180-degree immersive experiences viewable on platforms like and via devices such as or Daydream View. Designed for content creators, it supported live streaming and easy editing workflows, with a lightweight build for handheld or use. However, by , YI and other partners scaled back support for the VR180 ecosystem amid waning industry momentum for the format, rendering the Horizon a legacy product without ongoing updates or new hardware iterations. YI ceased major development of its action camera lineup after 2020, effectively discontinuing updates for models like the YI Lite, a budget-friendly -capable device launched in 2017 with electronic and a 150-degree . The YI Lite, along with predecessors such as the YI 4K and YI 4K+, saw their companion removed from app stores, leaving users reliant on outdated software and third-party alternatives for basic functionality. Similarly, the YI M1 , released in 2016 as YI's entry into interchangeable-lens with a 20-megapixel Micro Four Thirds sensor and video support, received firmware updates through 2020 but no new hardware or lenses, leading to its quiet discontinuation without a successor. This halt aligned with YI's pivot toward security solutions, abandoning the competitive consumer imaging space. Supporting its early imaging products, offered a range of accessories including spare lithium-ion batteries rated at 1010mAh for extended recording, quick-release mounts for helmets and bikes, and protective cases, which were essential for action-oriented use. As the company de-emphasized cameras and drones in favor of smart by the early 2020s, these peripherals were phased out from official production and sales, though third-party replacements remain available for legacy devices.

Criticisms and market challenges

In 2019, YI Technology announced a pause in active development for its products and the associated YI Action App, citing platform changes and shifting priorities, which left users without updates or new features beyond that point. This decision, effective around 2020, resulted in widespread user frustration as the app was eventually removed from app stores, rendering older cameras incompatible with newer smartphones and limiting access to or support. Community forums highlighted ongoing issues like connection drops and lack of , exacerbating perceptions of abandonment for early adopters. By 2025, faced significant backlash over its monetization strategies in the YI Home App, particularly intrusive advertisements and ed features that compromised usability. Users reported mandatory 30-second unskippable video ads upon opening the app or accessing live feeds, often at full volume, which delayed critical checks. Motion-activated clips, previously accessible via local storage, were moved behind a subscription costing $5–$15.42 per month, with reviewers noting this shift as a tactic. Cancellation processes proved arduous, requiring submissions with 3–5 day waits and unresponsive support channels, including disconnected phone lines. reviews, averaging 1.1 out of 5 stars, frequently cited these ads as aggressive pushes for cloud services, further eroding trust. Market challenges intensified these issues, as some YI camera models encountered limitations in functionality, funneling users toward paid options. Reports indicated that replaying motion alerts from microSD cards became unreliable or blocked in recent versions, with chunks of footage missing during events or AI features failing to save to drives. This reliance on subscriptions clashed with competitors like and , which maintained stronger market positions through integrated ecosystems and subscription-free options in some lines, contributing to YI's diminished visibility in the growing smart sector valued at over $23 billion in 2025. In response, YI introduced free trials for AI detection features and encouraged firmware updates via its website to address motion sensitivity and app stability, though implementation varied by model. Despite these efforts, customer service ratings remained low, with Better Business Bureau complaints highlighting unresolved billing and technical issues through 2025, and SafeWise explicitly advising against new purchases due to persistent support deficiencies.
