70mai 4K Omni Dash Camera review, bringing the fun back to the road!

More thoughts and deep-dives into specific features of the 70mai 4K Omni are located here in my unboxing thread:

Post in thread '70mai 4K Omni (unboxing & first impressions) (Sony Starvis 2 IMX678/IMX662, Wi-Fi 6/GPS, Novatek NT98530, 4K60 front + 1080p rear, HDR both channels)'

ADAS functions of the 70mai 4K Omni:


There are quite a few options available to the end user as shown in the screenshot below. Calibration is done within the app itself, and after a few visual prompts asking you to align within the markers, the Omni instructs you to drive around for a few minutes above 25km/h to complete calibration. This was performed seamlessly and without issue in my vehicle.

ADAS performs quite well in most situations with the 4K Omni, and could be quite useful for those driving older vehicles, that don't possess in-built ADAS. When the dashcam detects...

Won't work in my (British) car either, it is front wheel drive, so if you are accelerating, the front should lift, however hard you are pressing the brakes.

You can however put your foot very lightly on the brake pedal and light the brake lights, without causing any significant braking.

In some cars you can put the parking brake on at the same time, and the rear will dip down. That does tend to make people back off because they can't understand!

My eco box is so eco it won't dip even if I floor it.

Hi @Augustus ,
How would you recommend the 70mai 4K omni compared to the Viofo a229 pro?
I have a local installer so was just going to go the Viofo. But now researching was thinking of the 70mai simply for the sentinel feature. Any advice ?

The A229 Pro had some heat issues in the hot Aussie heat, but it turns off completely rather than the newer models which don't. I have mine paired with the Telephoto rtc300 which is a killer combo.

Tbh, Viofo always has the best video quality hands down but the 70mai has the sentinel and cloud functionality for real time alerts, which is why it stays in my vehicle. If you care about getting real time alerts, then go the 70mai. Otherwise a229 pro is plenty enough. Hope this helps mate.

Thanks for the info! I think I'll wait for the new Viofos to be released and then compare
