In 2026, you probably want a dashboard camera with 4K resolution. With 3840×2160 pixels, 4K UHD (Ultra High Density) is the highest resolution currently available for dash cams.
And 4K dash cams do indeed record stunning video! There’s one thing you should be aware of before you buy though: There are a lot of cameras advertised as “4K” dash cams that are actually fakes. This is true especially in the low to mid-price sector, up to about $150.
Fake 4K dash cams typically record at lower resolutions, and use tricks like interpolation to upscale video to UHD. Others do actually record 3840×2160 pixels, but only at reduced frame rates to lessen the load on the processor. Of course, tricks like these actually decrease the quality of the footage, instead of increasing it.
Below, we’ll show you some tried and tested dash cameras that definitely do record at a resolution of 3840×2160 pixels, with a frame rate of 30 frames per second (fps). We will also teach you a simple trick to spot the fakes.

What Is “True 4K” Resolution?
As per Wikipedia, 4K means “a horizontal display resolution of approximately 4,000 pixels”. This is anything but an exact definition. Sleazy marketers and manufacturers exploit the fact that the term “4K” isn’t actually clearly defined. And thus, they sell cameras that record at sub-par video quality, for a higher price.
On this web site, by 4K we mean a resolution of 3840×2160 pixels, or 2160p. This resolution is technically also known as 4K UHD (for Ultra High Density).
Therefore, our definition of a true 4K camera is a camera that can record at 2160p resolution, with a frame rate of 30 frames per second (fps). It must be able to do so without resorting to tricks such as upsampling or interlacing video. These tricks severely degrade video quality, and we do not consider them acceptable for a 4K dash cam.

All dash cams featured here have GPS, Wi-Fi, a lock file button, and several parking modes to choose from.
Let’s have a closer look at each of them:
Viofo A329S: Fisheye Cabin Lens
Price: n/a
Video quality (2CH): Very Good (3.8/5)
Reliability: Very Good (4.0/5)
Memory capacity: 512GB (4TB with ext. SSD)
Parking modes: Buffered, low bit rate, time-lapse w/ night vision
Other features: Wi-Fi 6, GPS, capacitor, lock file button, front CPL filter, external SSD
Optional extras: Bluetooth remote lock file button, rear CPL filter, hard wiring kit
The Viofo A329S (full review) is a 3-channel dash cam that was released in mid 2025. It’s an upgrade of the A329, which has since been discontinued.
The A329 introduced several cutting edge features, such as super night vision parking mode, Wi-Fi 6 support, and notably, the option to connect an external hard disk (SSD) for up to 4TB of extended storage.
Like the A329, the A329S has very good video quality, second only to the 70mai T800 (featured below). It comes with a fisheye interior lens that records the complete view out of the driver’s and passenger’s side windows, in addition of course to the interior of the car.
With its excellent field of view and impressive video quality, the A329S is a premium quality 4K dash cam. However, Viofo do not have a clooud, and the A329S is more expensive than the 70mai T800 which records even better video quality.
Vantrue N4 Pro S: Easy Installation
Price: Amazon US / CA / UK – more countries & vendors (ad)
Video quality: Good (3.2/5)
Reliability: Good (3.0/5)
Memory capacity: 1 TB
Parking modes: Simple, buffered, time-lapse, low bit rate
Other features: Wi-Fi, GPS, capacitor, lock file button, 3.19″ screen
Optional extras: CPL filter, hard wiring kit
The Vantrue Nexus 4 Pro (full review), or N4 Pro in short, is the most popular 3-channel dash cam on the market. Its front and interior lenses are both integrated into the main unit, so you don’t have to mount an extra interior camera on the windshield. This means there’s also one less cable to install.
You can configure the camera either with a smart phone app, or through menus using the integrated 3.19″ screen. For a 3-channel dash cam, the N4 pro is relatively easy to set up and use.
Video quality is good on average, and all 3 channels support HDR for better night visibility.
The N4 Pro supports four different parking modes: Simple (impact triggered), buffered, time-lapse, and low bit rate. We recommend using buffered or time-lapse modes.
70mai T800: Best Video, Editor’s Choice
Price: Amazon US / CA / UK – more countries & vendors (ad)
Video quality (2CH): Very Good (4.0/5)
Reliability: Very Good (4.0/5)
Memory capacity: 512GB (card included)
Parking modes: Time-lapse, impact, combined
Other features: Wi-Fi 6, GPS, capacitor, lock file button
Optional extras: CPL filters (front and rear), LTE module
The 70mai T800 is one of the first dash cams to record 4K resolution both front and rear, and in excellent quality at that. It’s our favorite camera as of December 2025.
With Starvis 2 sensors and HDR across all 3 channels, the T800 produces the best video quality of all dash cams we’ve reviewed so far. And as a bonus, it comes with a 512GB card included!
This camera supports cutting-edge features such as fast Wi-Fi 6, and cloud connectivity if you get the corresponding LTE module. That module costs about $50 extra, and is built into the hard-wiring kit.
If you don’t want cloud, but do want parking mode, the regular (non-LTE) hard-wiring kit is only $20. Bear in mind that 70mai dash cams do not support buffered parking mode.
Available parking modes are time-lapse, impact-triggered, or a combination of the two: In combined parking mode, the camera will record time-lapse until an impact is detected, then switch to normal recording (with sound) for 30 seconds with all 3 cameras. So you get a pretty good chance of catching any perpetrators.
Viofo A229 Pro: Great Video, Supports 2 Or 3 Channels
Price (2CH): Amazon US / CA / UK – more countries & vendors (ad)
Video quality (2CH): Very Good (3.5/5)
Reliability: Very Good (4.0/5)
Memory capacity: 512GB
Parking modes: Buffered, time-lapse, low bit rate
Other features: Wi-Fi, GPS, capacitor, lock file button, CPL filter
Optional extras: Bluetooth remote lock file button, hard wiring kit
The Viofo A229 Pro (full review) was released in late 2023. It is available in 2-channel (2CH) and 3-channel (3CH) configurations. The 3CH version costs about $30 more than the 2CH one.
This camera’s video quality is very good in most situations. The only exception is the rear channel at night, which could be a bit better on dark roads.
Due to this camera’s high bit rates, it’s a good idea to get a memory card of sufficient size. We recommend using at least a 256GB SD card. The maximum supported card size is 512GB, which is enough to hold over 12 hours of front and rear video.
Like the Viofo A329S, the A229 Pro is picky with which SD card brand it accepts. The manufacturer recommends to either use their own brand (Viofo), or SanDisk Max Endurance. Other cards can cause stability issues.
When used with a compatible memory card, the A229 Pro is highly reliable.
70mai A810: Best Value
Price: Amazon US / CA / UK – more countries & vendors (ad)
Video quality (1CH): Very Good (4.0/5)
Reliability: Good (3.0/5)
Memory capacity: 256GB
Parking mode: Non-buffered only
Other features: GPS, Wi-Fi, lock file button, 3″ screen
Optional extras: CPL filter, hard-wiring kit
70mai is the dash cam brand of the well-known Chinese company, Xiaomi (think mobile phones). They have been producing good quality dash cams for many years now, and have gained a reputation of being a reliable mid-price brand.
The 70mai A810 (full review) is great as a single channel dash cam. It does support connecting a rear camera also, but the downside is that with a rear camera connected, the frame rate of the front camera will drop from 30fps to 25fps. This makes the video a little less fluid and decreases your chances of capturing license plates, if only by a little.
While the difference is not huge, we did define “true 4K” as being 2840×2160 at 30fps. So by this definition, the A810 is only a true 4K dash cam when it’s used in 1CH mode.
If you do want the rear camera, it records at 1080p resolution.
The A810 supports HDR, GPS, Wi-Fi, and has a lock file button. It does come with an internal battery though instead of a capacitor. Batteries are less heat resistant, so be careful if you will be parking in the sun in a hot climate.
If you’re happy with a 1-channel dash cam (or don’t mind the reduced frame rate with the rear camera connected), the 70mai A810 is great value for around $160 at the time of this writing.
70mai A800S: Most Affordable True 4K Dash Cam
Price: Amazon US / CA / UK – more countries & vendors (ad)
Video quality: Fair (2.25/5)
Reliability: Good (3.0/5)
Memory capacity: 256GB
Parking mode: Non-buffered only
Other features: GPS, Wi-Fi, lock file button, 3″ screen
Optional extras: CPL filter, hard-wiring kit
The 70mai A800S (full review) is the most affordable true 4K dash cam available. While there are many dash cams labelled “4K” that cost even less, those are most likely fakes, and we will look at some of the most well-known ones in the next section. If you find any true 4K dash cams below $100, please let us know.
While the A800S won’t give you the same video quality as the more advanced products listed above, its video quality is quite acceptable for a price around $100 (without the extras).
Available extras include a CPL filter (~$10) and hard-wiring kit (~$15). When hard-wired to the car’s fuse box, the camera can run in impact-triggered parking mode when the engine is off. It does not support buffered parking mode.
The A800S comes with GPS, Wi-Fi, and a lock file button. It also has a 3″ screen on the main unit.
Just like the A810, it uses a battery instead of a capacitor, making it less heat resistant than a camera with a capacitor.
Fake 4K Dash Cams
Unfortunately, some manufacturers see fit to just stick a 4K label on a dash cam which can’t actually record true 4K. As stated above, a true 4K dash cam must be able to record 3840×2160 pixels at 30 frames per second (fps).
We’re compiling a list of fakes here for your convenience.
Technical Background
Many fake 4K dash cams come with a sensor that can’t actually record 4K resolution.
A 4K camera needs at least an 8 megapixel (MP) sensor. Let’s do the math: 4K means 3840×2160 pixels. My calculator says 3840 * 2160 is 8,294,400. That’s over 8 million, or 8MP in short.
A 1080p camera has 1920×1080 pixels. 1920 * 1080 is 2,073,600 pixels, or 2 megapixels.
A 1440p camera would have 2560 * 1440 = 3,686,400 pixels, so it needs a 4MP sensor.
How To Spot A Fake 4K Dash Cam
Avoiding the scams is actually quite easy with this simple trick:
True 4K dash cams have to have an 8MP sensor. So just check which sensor a camera uses. If it’s less than 8MP, there’s no way it’s going to record at 4K resolution the way we define it. That is, 3840×2160 pixels, at 30fps, and without resorting to tricks such as upsampling or interlacing.
Alternatively, just check the cameras listed in this article.
We’re trying to make this overview as complete as we can, so if you have any examples of fake or real 4K dash cams not listed here, please let us know.
Examples Of Fake 4K Dash Cams
Here’s an (incomplete) list of dash cams that claim to be 4K, but that use the Omnivison OV4689 sensor (not a bad sensor by any means, but it only has 4MP):
- Acekool 4K: OV4689 sensor → fake 4K
- Azdome GS63H: OV4689 sensor
- Rexing V1 4K UHD: OV4689 sensor
- Rove R2-4K: OV4689 sensor
Other fake 4K dash cams:
- Aukey 4K dash cam DR02 J: Aptina AR0521 sensor with just 5MP
- Redtiger F7N: Sony IMX335 sensor, also just 5MP
- Redtiger F17: also Sony IMX335
- Rexing V5: Sony IMX335 sensor, 5MP
- Rove R2-4K Dual: Sony IMX675 sensor, which is Starvis 2 and better than the one in the older R2-4K, but still only 5MP
- Rove R2-4K Pro: Sony IMX335 (5MP)
- Toguard Dash Cam 4K: 4K video is interpolated. (Also the fact that it can’t handle memory cards over 32GB should alert you. 32GB is ridiculously small for a 4K camera.)
- Vantrue S1: Has 1080p sensors. 4K is interpolated
- Wolfbox G930: Sony IMX335 sensor, 5MP
Additionally, readers have advised us that the following cameras are also fake 4K:
- Campark DC30
- Lifechaser 4K OLED
- WonVon W4K
