Launched in May, 70mai’s Dash Cam 4K Omni offers a single intelligent eye. Rotating a full 360 degrees, the camera combines magnetic sensor-directed gimbals and AI-powered motion detection to spot trouble in real time and record with greater precision. (Recording can be turned off at any time.) “If you’re in a supermarket when someone hits your car, this device will notice, lock onto the other car, record high-definition evidence, and send an alert to your phone,” says product manager Zhiyi Liu. **Buy Now:** 70mai Dash Cam 4K Omni on [Amazon](https://amzn.to/46SlVRc "undefined") These are independent reviews of the products mentioned, but TIME receives a commission when purchases are made through affiliate links at no additional cost to the purchaser. 70mai Dash Cam 4K Omni: The Best Inventions of 2025 ```json [{"@context":"https://schema.org","@type":"Article","@id":"https://time.com/collections/best-inventions-2025/7318265/70mai-dash-cam-4k-omni/","mainEntityOfPage":{"@type":"WebPage","@id":"https://time.com/collections/best-inventions-2025/7318265/70mai-dash-cam-4k-omni/"},"headline":"70mai Dash Cam 4K Omni","datePublished":"2025-10-09T11:00:16.000Z","dateModified":"2026-04-13T11:54:47.234Z","description":"","url":"https://time.com/collections/best-inventions-2025/7318265/70mai-dash-cam-4k-omni/","keywords":["Tech","E-Commerce","list","franchise","Magazine","best inventions","Special Project","sponsorshipblock","Accolades","Best Inventions 2025"],"thumbnailUrl":"https://static.time.com/v3/assets/bltea6093859af6183b/blt11ba40b111fcf283/6998ca39d32e93b6accd760b/70mai-Dash-Cam-4K-Omni-TIME-best-inventions-2025.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","author":[{"@type":"Person","name":"Chris Norris","jobTitle":null,"url":"https://time.com/author/chris-norris/"}],"creator":"Chris Norris","articleSection":"Business","image":[{"@type":"ImageObject","url":"https://static.time.com/v3/assets/bltea6093859af6183b/blt11ba40b111fcf283/6998ca39d32e93b6accd760b/70mai-Dash-Cam-4K-Omni-TIME-best-inventions-2025.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","width":1200,"height":675}],"publisher":{"@type":"Organization","name":"Time","url":"https://time.com/","logo":{"@type":"ImageObject","url":"https://time.com/images/logo.png","width":528,"height":156},"foundingDate":"March 3, 1923","sameAs":["https://www.facebook.com/time","https://www.instagram.com/time/?hl=en","https://twitter.com/time","https://www.pinterest.com/timemagazine"]}},{"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"item":{"@id":"/section/business/","name":"Business"}},{"@type":"ListItem","position":2,"item":{"@id":"/tag/time-section-tech/","name":"Tech"}},{"@type":"ListItem","position":3,"item":{"@id":"https://time.com/collections/best-inventions-2025/7318265/70mai-dash-cam-4k-omni/","name":"70mai Dash Cam 4K Omni"}}]}] ```
