70mai Dash Cam 4K Omni
Put its spread out design to one side , and the 70mai Dash Cam 4 K Omni is an impressive 4 K bolt cam . It captures frizzy footage in a ambit of light and weather condition , and is one of the good dash cams I ’ve try at night . If you go for the two - television channel bundle as tested here , you ’ll also get a adequate 1080p rear camera .
This dash cam also has utile driver aids , include a lane departure warning that works reliably , along with pedestrian and cyclist alerts . I ’m less confident by its rotating political party illusion , though . Capturing the left , right , or cabin views could be utile in some situations , but the selfie and vlog modes are too trouble .

Key Features
Introduction
The 70mai Dash Cam 4 K Omni is a 4 M camera with a conflict . While most of the metre it faces forwards , it ’s built on a motorised turret that let it turn through almost 360 degrees , capturing more of the route or your fomite ’s internal . you could optionally buy it paired with a established rearward - windowpane camera – that ’s the bundle I ’m testing here .
I ’ll come on to the go around mount , but first let ’s look at the master specifications . The front tv camera shoots 3,840×2,160 solvent video at up to 60 frames per 2d ( fps ) , although it ’ll only do 30fps if you have a rear camera link up . The rear contend 1,920×1,080 footage at 30fps . The front camera looks after storage for both , with a MicroSD one-armed bandit that corroborate up to 512 GB cards .
Design and features
This is an unusual style Cam River , looking a little like an invert robot clinging to your windscreen . Most of its hummer - form body remain still . It ’s on this static part that you ’ll find a 3.6 cm color screen , along with a MicroSD board slot and some basic controller for the fare organisation . Only the bottom third or so of the gadget can rotate – that ’s where you ’ll find the camera lens .
The 70mai Dash Cam 4 K Omni fixes to your windshield via a slimline circular climb . It ’s great that 70mai include a duet of electrostatic pricker for this , along with an extra sticky pad , so it ’s prosperous to position and warehousing , or even to swop it into a novel fomite .
you could wriggle the camera cursorily on and off its mount , although both the power and rear television camera cable secure directly into the photographic camera body , which creates a morsel more dogfight if you ’re in the habit of take the dash cam when you park .

Once you ’ve fixed it to the windscreen , this photographic camera lets you adjust it for sales pitch ( up / down ) , but not for roll ( banking left or right ) . The motorised gun turret alters the yaw ( turning left or right ) once you ’ve got it set up .
Things are a turn more dewy-eyed with the rear television camera , which is a small cylindrical twist that sticks onto the rear window .
Again , this comes with a couple of electrostatic sticker and a spare sticky pad , so it ’s quite gentle to get into place . The camera trunk itself twists , letting you fine - air its perpendicular objective , but not any other axis . you could utilise either the app , or the screen ’s live view to get both cameras aim in the right directions .
While the front photographic camera feels well made , I was n’t too impressed by the rear ’s cheap - feeling charge card . While I ’m at it , I did n’t love the supplied cigarette baron adapter either ; its dual USB - A slots were quite resistant to cause cables inserted .
you’re able to corrupt a hardwiring outfit for this television camera , and US consumers can also buy it with an LTE ( cellular ) modem kit . The former provides constant power , letting you use the 70mai Dash Cam 4 K Omni ’s parking protection feature . These offer the common reassurance of notice an impact , but this camera can also perform the neat trick of apparent movement - tracking people as they walk around your car . If you ’re in a patronise territory , the LTE kit adds exigent alert , and outside viewing and trailing .
Once you ’ve physically fitted the 70mai Dash Cam 4 K Omni , you ’ll need to deploy the 70mai app to configure all of its features . This is straightforward enough , and the initial apparatus lets you select the angle it ’ll default to when you change by reversal it on – letting you capture the full front prospect if you ’ve had to mount the tv camera off - centre .
The app offers the common cartridge holder depository library , letting you browse , purview and download footage to your phone , although it does n’t have an intuitive timeline purview as you might get hold in the best apps . Alternatively you’re able to just belt down out the MicroSD add-in and browse it on a computer .
The terminal apparatus dance step is to configure the advanced number one wood - assistance system of rules ( ADAS ) , which you ’ll postulate to do while stationary , before postulate a short drive to let the organization calibrate itself . This hyphen camera offers forward-moving hit monition , pedestrian and cyclist hit monition , vehicle - in - front alerts , and a lane - departure warning , but you’re able to inactivate any or all of them .
The 70mai Dash Cam 4 K Omni is only the second photographic camera I ’ve reviewed to use the Sony STARVIS 2 IMX678 sensor , which is a eminent - end potato chip specifically contrive for surveillance and dash cam use . While the superbViofo A329is capable of 60fps transcription even with a rearward television camera connect , here you ’ll be limited to 30fps if you also have a rear camera .

Even so , this dash cam eats up storage space very quickly . Every minute the rear camera salve a 78 MB file , while the front grow variable file size from around 230 - 390 MB depending on conditions . I measured an norm of about 250 MB from the front , giving a total of roughly 325 MB for every minute of recording . At that charge per unit , you ’ll fill up a 64 mebibyte memory add-in in a small over three hour of driving . Unless you only make short trips , I ’d recommend a bigger poster .
One final noteworthy feature is this camera ’s ‘ personality ’ , along with its voice control features . I ’m normally scornful of devices that preface themselves , but there ’s something reasonably endear about the 70mai Dash Cam 4 K Omni ’s ‘ Maix ’ identity , combining occasional prompts and warning with a human face exhibit on the filmdom .
you could practice a range of phonation control while drive to state Maix to capture to the remaining or right of your fomite . you may also instruct them to manoeuver at the cabin , although without any infrared light origin this is n’t in particular utile at Nox .
It ’s well-to-do to realise the indigence for these unobtrusive features , but I ’m less confident by the fact you could also take a selfie , or inject a vlog . In the latter , the camera pans full around its range before prompting you to model , which seems like an unnecessary distraction from driving .
Performance and video quality
I tested the 70mai Dash Cam 4 K Omni in March 2025 , when I could submit it to brilliant bounce skies , sour nights , and the occasional downpour . The most significant thing I discovered is that it ’s a very capable style cam , bewitch excellent , crisp footage in almost any lighting conditions .
By day , item-by-item frame were sharp enough that I could read almost every number plate in videos shot around townsfolk : it ’s hard on quick road where there ’s a agile culmination speed , but this sprint River Cam still performed well .
The television camera apprehend well with low sun , capturing detail on the shaded side of cars passing under blaze sunshine .
It was also especially telling at night where , like the Viofo A329 , it exposed far more detail of dimly - lit pavements than other cameras I ’ve try .
It was unusually good at capturing numeral plate on my nighttime clock time tour around a city occlusion . This baffle a particular challenge for elan cams given that plates are design to reflect your own headlights , creating a post that ’s much brighter than its surround . On this camera , they did n’t ‘ blow out ’ to white – I was yarn-dye by how many registrations were legible despite a full striking from my lights .
behind - facing cameras are always inferior to the main flair photographic camera whole , a trouble that ’s compounded at Nox by the fact it ’s usually darker behind your cable car than in front of it . The optional camera bundled with the 70mai Dash Cam 4k Omni is n’t the effective I ’ve tested . By day , its footage is generally good enough to capture anything run short on behind you , but I find out that only the eye of the chassis was crisp . Off - centre features , and especially those nearest the television camera , tended to confuse significantly , even at comparatively low speeding .

By night the rearward camera exposed some item under streetlights , but it did n’t seem as capable of appropriate figure plates as some other rear - facing cameras I ’ve tested – even with help from my car ’s bright brake lights .
With many modern cars now having onboard gadget driver assistance features , not all owners will want help from their flair River Cam . The lane modification , pedestrian and other warnings build into my motorcar all work brilliantly , andhave the advantage that they ’re linked to system that can help me brake or steer my mode out of difficulty .
That enounce , driver of old vehicle might observe warnings helpful , and the system built into the 70mai Dash Cam 4 K Omni seem to work particularly well . It spotted whenever I commute lane on a motorway , warn me when the railroad car in front dress off from stationary , and tended to warn passably dependably when I was portion out route quad with pedestrian or bicyclist . This camera also monish when you ’re rapidly closing up on the gondola beforehand .
I was also impressed with Maix ’s voice dominance . This reacted quite reliably to anyone in my family giving direction to take selfies or shoot vlogs – something I come to rue when driving three young shaver home from a party . Perhaps more imposingly , in all my testing the camera only mistakenly activate once .
I was n’t gain ground over by the front camera ’s rotating party tricks . Even in enough sparkle and at irksome speed , nearby target tended to blur as they streaked past the left windowpane .
great separation from the photographic camera mean there was less comparative movement , and less blurring in footage shot to the rightfulness . However , the wide-cut - slant lens entail there ’s mass of your cabin in the shot , and the camera struggle to expose both at once .
With no infrared light to help illuminate the cabin , selfies and vlog footage also became pretty dark-skinned into the even – the exposure is aid in this image by my headlights , ponder off the front of my house .
This television camera for sure would n’t be a desirable solution for cab drivers looking for a way to shoot incident inside their fomite at dark , and there ’s no cabin camera contribute - on available .
Should you buy it?
The 70mai Dash Cam 4 K Omni shoots excellent front TV , and comely rearward footage . It manages to combine both with strong number one wood assistance lineament that in reality work . It ’s a good option if you need a bolt cam to record drive , and facilitate keep them safe .
This photographic camera ’s revolve lens of the eye is arguably a gimmick , and interacting with it could turn out a distraction when you should be focused on safe driving . There are better choice if you want a dash cam to fit and forget
Final Thoughts
I ’m not a great fan of voice ascendency or machine driver assist in style cams , so it ’s a recognition to the 70mai Dash Cam 4 K Omni that neither particularly nark me here . Both scheme ferment well , with very few false alarms , making this a hard-nosed alternative if you do need a style cam that fall in you extra eyes on the road . The irony is that this camera ’s revolve genus Lens also supports frivolous features that could take your attention away from it .
While I can see the use in being capable to conquer to the left or right of your car , I ’m not sure how the police would oppose should you stimulate an accident while put for a selfie or taking a vlog – and remember it would then be an offence to cancel the footage . This camera is a skilful alternative if you need high video quality and helpful machine driver aid . But if you ’re only really concerned about the former , corrupt the Viofo A329 instead . And if neither seems ideal , hold back out ourBest Dash Cam guidebook .
