70mai 360 Omni 4K Dash Cam: one-minute review
I remember reading the review of the original 70mai 360 Omni Dash Cam just over a year or so ago and thinking it was something of a curio. After all, it’s easy to ponder over the appeal of a camera that can rotate 360 degrees while attached to the windshield of a car. As it turns out though, the 70mai 360 Omni is ideally suited to anyone who wants to record a variety of angles using just one in-car camera. It is also perfect for anyone who vlogs from behind the wheel.
The new and improved version of the original is called the 70mai 360 Omni 4K Dash Cam and the not-so-secret is in the title; a new Sony Starvis 2 IMX678 sensor which delivers crisp and clear 4K video footage up to 60fps. Performance is therefore beefier than the earlier incarnation, but there are other highlights too, including AI Motion Detection 2.0, 70mai’s after dark tool called Lumi Vision, voice control and dual-channel HDR capability.
If you’ve never seen it before, the Omni is a quirky looking creation. The design hangs down from your windshield in a similar way to the smaller and less capable Nextbase Piqo. In fact, it’s a slightly odd thing to look at, far removed from the more conventional design lines of, say, the Viofo A229 Pro Dash Cam or indeed any of the other best dash cams out there for that matter. However, the design is perfect for the task in hand as it includes a revolving lower section that contains the lens assembly, which rotates as and when it’s needed.
Another addition this time around is the option for two-channel shooting, thanks to this particular bundle containing a secondary rear-facing camera, which captures video in 1080p. It’s more conventional to look at than the front-facing Omni and connects to the main unit via a lengthy piece of cable. Both cameras can be controlled using 70mai’s app, which has been reinvented in order to exploit the newer features and functions offered by the upgraded Omni unit. Voice activation is another bonus control option.
As you’d expect from an upgraded product, the 70mai 360 Omni 4K Dash Cam is more potent. In fact, 70mai’s own figures suggest a 68 percent improvement in sensor size compared to the original Starvis, a 90 percent improvement in light sensitivity and a 100 percent improvement in low light performance. In addition, there’s a larger rear screen, improved field of view, beefier Wi-Fi plus a supercapacitor/ button cell battery setup for increased efficiency. On paper, the 70mai 360 Omni 4K Dash Cam sounds like a drastic improvement over the older product.

70mai 360 Omni 4K Dash Cam: Design
On first impressions, the 70mai 360 Omni 4K Dash Cam looks remarkably similar to its lower specification predecessor. The bulbous body design has been retained and this both looks and feels like a quality component. However, as noted in the previous review, the body does need to be handled with care as the lower part contains the 360-degree rotating lens section, which if forcibly handled feels like it could affect performance. Aside from that, the overall design of the body feels rugged enough and is manufactured from quality plastic.
As before, the buttons on the side are brightly colored in red while on the other side of the unit, there now sits a microSD card slot. This also has a rubberized type of cover on it to keep dust, dirt and moisture out, even when the card is in situ. Meanwhile, there’s an angled joint that divides the sticky part of the windshield attachment with the rest of the body, so it’s quick and easy to get the camera positioned correctly, no matter what the angle of the screen is.
Around at the back of the main camera body is the 1.4-inch IPS screen, which is a step up from the 1.2-inches of the previous model. Again, the screen covering looks and feels rugged enough while the resolution of the various graphics is crisp and clear. Most of the management of the 70mai 360 Omni 4K Dash Cam is best done via the supplementary app, although there is also the added bonus of voice control, which is useful when you’re behind the wheel.
The same level of quality extends to the rear camera unit as well. This is a fairly standard barrel-type of design, with a rotating lens protruding at one end along with a short cable that needs to be press fitted to a longer one. This then feeds into the main camera unit via a small jack plug next to the power cable. Expect to spend some time pushing the associated cables behind trim panels, but there’s a small plastic tool included to help you do just that.
70mai 360 Omni 4K Dash Cam: Performance
As always with setting up a dashcam for the first time, some of this is best done before you get the camera into position. Equally, however, it does need to be on the windshield so the angle can be previewed, via the app ideally, and then adjusted for an optimal view of the road. The same goes for the rear-facing camera, which in some ways I found even trickier to position due to the angle of the rear glass and an obtrusive parcel shelf. Expect to take some time for this setup process.
I haven’t tried the original incarnation of the 70mai 360 Omni 4K Dash Cam, but the performance delivered by the new model seems like a step up, especially based on the specifications. The Sony Starvis sensor is beefier than before and there’s the 4K capability. After popping a microSD card in and running through the setup process, the camera was quick to get started. Registering an account was the most time-consuming part of the process because you get sent a code to your email, which then needs to be dialled in before a time limit runs out.
Nevertheless, once everything is up and running I found the cameras to be everything I expected from them. Front-facing 4K footage is just that, and of a very decent quality. Adjustments can be made to video settings if storage is an issue too, although 70mai does have a cloud option within the package if the microSD card isn’t going to be substantial enough, even though recordings are done in the usual loop fashion. The rear-facing footage is very acceptable too, with a good level of clarity that allows license plates to be read and recorded as and when needed.
I do like the way the 70mai 360 Omni 4K Dash Cam can be controlled using voice commands, which works particularly well for the vlogging environment. Anyone who needs to tell a tale while they’re at the wheel and doesn’t want to be distracted by fiddling with controls will find this feature a real boon. On command, the lens simply rotates around the cabin and focuses on the driver, and it works to good effect, although there is a slight fish-eye effect as it pans around.
The 70mai app is okay and comes with all of the features and functions I needed. However, alongside the rest of the kit setup, it did feel a little less impressive than alternatives from the likes of Nextbase, and is perhaps the weakest link in the chain. Everything works as expected, but I think it could do with a little tightening up on the functionality front. It’s not always quite as intuitive as I’d like either and I quite often found myself fiddling inside menus when I shouldn’t really have had to. It’s not a deal breaker, just mildly irritating in places.

How I tested the 70mai 360 Omni 4K Dash Cam
- I installed the dash cam into a test car for an initial period of two weeks
- I used it for several journeys during both day and night
- I connected it to my phone and downloaded recordings for comparison
70mai loaned me the Omni and supplied everything I needed to test it. This included a microSD memory card and a hard wire kit, which is an optional extra. I installed the camera in a test vehicle, which I was also reviewing at the time, which allowed me to try out all the features and functions. Testing also meant plumbing in all of the wiring around the car, which meant I was able to check that cable lengths were adequate even in large size vehicle.
I used the 70mai Omni over an initial period of two weeks, although I have since continued to use it in test vehicles being used for review purposes. However, due to the temporary nature of test loans I have been unable to permanently fix the dash cam into a vehicle using the hard wire kit. Nevertheless, the test period did allow me to explore all of the core features and functions of the 70mai Omni 4K, aside from the additional parking options that come as a result of the hard wire installation. The dash cam was also used in a variety of winter conditions, which included plenty of low light and after dark scenarios, along with lots of variation in temperature.
