We're back at it again in 2025 with the first of many upcoming releases from 70mai, the Omni 4K (known as the X800 in the Chinese market). Would like to extend a thank you to 70mai for giving me the opportunity once again to test-drive their latest and greatest. This year, we get quite a big upgrade to the front with the Sony Starvis 2 IMX678 F1.7 aperture sensor, and 4K60fps recording enabled by the NT98530 chipset (only in single-channel mode though)! The rear camera sensor RC14 also sees some love this year with the move (finally) to the Starvis 2 IMX662 sensor, which is a first for rear-module sensors now able to reap the benefits that Starvis 2 brings in term of night-time footage. The other big change this year is the deletion of batteries from the 70mai product line, and I'm happy to report that the 4K Omni has a supercapacitor on board!
Turning to the box contents, we are greeted by the familiar black packaging of 70mai products, with a two-tone silver finishing this time around. Contained within the box is the front and rear dashcams (with respective power cabling), black plastic pry tool, and 12V cigarette lighter car charger that has an additional USB-A port on board. We also have the usual suspects of spare mounting adhesives and electrostatic mounting stickers. No microfibre cleaning cloth is included with the 4K Omni, and there will be a separate CPL filter made available for purchase soon (more on this later).
First impressions are positive of the 4K Omni, even with it's form factor. Understandably many may be put off by it's apparent bulbous body, but I can assure you it is not detrimentally heavy, nor is it remarkably large either. There is a 1.4-inch IPS display that does display animations in the form of MaiX, 70mai's mascot. I am glad to see this make it to the global model as I was afraid it was not going to make the final cut. Some may dismiss this as a gimmick, but I find the animations fun and adding some joy to the experience of owning and operating this dashcam. I would be remiss not to mention that there is also a 340 degree pan with the front camera, and that response speed has been improved by 70% compared to the last generation Omni (AI Motion Detection 2.0). There is also a light ring that wraps around the body of the 4K Omni - glowing blue to signify operation, and red when sentinel mode is activated (motion-tracking when suspicious activity is detected whilst in parking mode). If I had to nitpick, the red power and menu operation buttons on the side of the Omni 4K are somewhat rattly, but this doesn't detract from an otherwise excellent build quality.
There are other miscellaneous additions to the Omni 4K that are new to the 70mai line. We now have the implementation of 70mai's proprietary Lumi Vision for parking mode (akin to for example, Viofo's Super Night Vision) - which seeks to brighten dimly-lit night scenes by adjusting exposure, gain and noise reduction. Real-time battery voltage monitoring through the 4G hardwire kit is another welcome addition to the dashcam, which gives users peace of mind by being able to track their car battery voltage status. Finally, ADAS makes a return with newly-added pedestrian and cyclist collision detection.
Installation of the 4K Omni was once again a relatively painless experience, with included firmware version being on v1.0.78.ww with a build date of January 2025. I was already a fan of the 70mai A510, but there are so many quality-of-life improvements with the Omni 4K, that I am immensely looking forward to taking this camera for a spin (no pun intended) to see what it can do. Stay tuned.
