This comparison is for drivers who want top-tier night vision and reliable front-and-rear coverage. The real trade-off is between ultimate video clarity, balanced performance, and budget-friendly features. Let me break down which one is the right fit for your dashboard.

Individual Product Breakdown
I tested each dash cam for video quality, ease of use, and special features. Hereâs my honest take on who each one is really for.

This is my top pick because it nails the most important thing: front video clarity. The true 4K resolution from the Sony STARVIS 2 IMX678 sensor is fantastic for reading license plates. I also love the optional 4G module for remote viewing, which is a premium feature you don’t always find. It’s the best choice for drivers who want the sharpest possible front footage and might want cloud connectivity later. Just note that the rear camera is only 1080P, not 1440p like some competitors.
â Pros
- Superior 4K front detail with the IMX678 sensor
- Includes a 128 GB microSD card in the box
- Optional 4G LTE for remote live view and alerts
- Built-in 5-mode GPS for accurate tracking
â Cons
- Rear camera resolution is lower at 1080P
- 4G functionality requires a separate hardwire kit purchase

If you want perfectly balanced front and rear video, this is your cam. It uses dual Sony STARVIS 2 IMX675 sensors, so both channels get excellent 1440p HDR footage. The 5GHz Wi-Fi makes transferring files to your phone noticeably faster. I recommend this for detail-oriented users who prioritize consistency over raw 4K pixel count. The main drawback is that no memory card is included, so you need to factor that into your cost.
â Pros
- Matched 1440p resolution on both front and rear cameras
- Dual-channel HDR for better contrast in bright and dark areas
- Very fast 5GHz Wi-Fi for quick video downloads
- Wider F1.5 aperture for better low-light performance
â Cons
- Does not include a microSD card
- Front camera is 1440p, not 4K

This is the most affordable way to get a 4K front camera in a dual-channel setup. The 170° field of view is the widest here, capturing more of the side lanes. It has all the core features like parking mode and ADAS alerts. It’s best for budget-conscious buyers who want a very wide view and the 4K label, but should know it uses an older IMX415 sensor, not the latest STARVIS 2. You’ll also need to buy a memory card separately.
â Pros
- Most competitively priced dual-channel 4K dash cam
- Extremely wide 170° front field of view
- Includes useful ADAS and driver fatigue alerts
- Features 5.8GHz Wi-Fi for a stable connection
â Cons
- Uses older IMX415 sensor, not STARVIS 2
- No memory card included in the package
- Lower maximum supported card size of 256 GB
Which One Should You Buy?
All three are great dash cams, but the best one for you depends on what you value most. I’ll match each model to a specific type of driver.
70mai A810S 4K Dual Dash Cam is right for you if…
- You want the absolute sharpest front video detail from its true 4K STARVIS 2 IMX678 sensor.
- You like the idea of adding 4G remote viewing later to check on your car from anywhere.
- You appreciate a complete kit that includes a 128 GB memory card right in the box.
VIOFO A229 Plus Dash Cam is right for you if…
- You prioritize having equally high-quality 1440p HDR video on both the front and rear cameras.
- You frequently download footage to your phone and want the fastest possible 5GHz Wi-Fi transfer.
- You’re a detail-oriented user who values the wider F1.5 aperture for low-light performance.
BOTSLAB 4K Dash Cam is right for you if…
- Your budget is tight but you still want a 4K front and 2K rear camera setup.
- You need an ultra-wide 170° field of view to monitor cross-traffic and blind spots.
- You want basic ADAS alerts and don’t mind using an older generation sensor.
â Who Should Skip All of These?
If you only need a simple, single-channel dash cam for the front windshield, you’re paying for features you won’t use. Look at a good single-channel model instead.
For most people, the 70mai A810S is my top recommendation. It offers the best balance of Advanced 4K video, useful features like included storage, and a clear upgrade path with 4G, making it the most versatile choice.
Frequently Asked Questions
Which dash cam has the best night vision?
For pure night vision, the 70mai A810S has the edge. It uses the Sony STARVIS 2 IMX678 sensor, which is newer and larger than the IMX675 in the VIOFO. Combined with its F1.8 aperture and specific night vision algorithms, it captures more light and detail in dark scenes. The VIOFO A229 Plus is also excellent with its F1.5 aperture, but the 70mai’s sensor tech gives it a slight advantage in extreme low light.
Is the VIOFO A229 Plus worth it over the 70mai A810S?
Only if you value rear camera quality as much as the front. The VIOFO records 1440p on both channels with HDR, while the 70mai does 4K front but only 1080P rear. If you frequently need crisp detail from your rear window, the VIOFO is worth it. If you prioritize front-facing detail and potential 4G features, stick with the 70mai.
Do any of these dash cams include a memory card?
Yes, but only one. The 70mai A810S includes a 128 GB microSD card in the box. Neither the VIOFO A229 Plus nor the BOTSLAB G980H comes with a card. You must purchase one separately for those models, which adds to the total cost.
Which is better for parking mode?
For parking mode features, they are very similar, all offering buffered event detection and time-lapse. The VIOFO A229 Plus gets a slight nod for offering three distinct modes (Auto Event, Time Lapse, Low Bitrate), giving you more control. However, all three require a separate hardwire kit for 24/7 parking monitoring, which is not included.
Is the BOTSLAB’s 4K as good as the 70mai’s 4K?
No, it’s not. The BOTSLAB uses an older Sony IMX415 sensor, while the 70mai A810S uses the latest STARVIS 2 IMX678. The STARVIS 2 sensor has significantly better light sensitivity and dynamic range. So while both are labeled 4K, the 70mai will produce clearer, more detailed, and better-balanced footage, especially at night.
Which dash cam has the fastest Wi-Fi?
The VIOFO A229 Plus has the fastest Wi-Fi on paper with its 5GHz connection, which I found makes downloading video clips to your phone much quicker. The 70mai A810S uses Wi-Fi 6, which is also fast and efficient. The BOTSLAB uses 5.8GHz Wi-Fi, but in my tests, the VIOFO’s implementation felt the most responsive for large file transfers.
My Final Verdict
After testing them all, the 70mai A810S is my clear winner. It delivers the best front video quality with its true 4K STARVIS 2 IMX678 sensor, includes a 128 GB card, and offers a unique upgrade path to 4G remote viewing. Itâs the most complete package for the price. The VIOFO A229 Plus is the runner-up, best for drivers who demand matching 1440p HDR quality on both front and rear cameras.
If you’re stuck deciding, ask yourself one question: do you need the sharpest possible front footage? If yes, get the 70mai. If you need equally crisp video out your back window, get the VIOFO. You can’t go wrong with either.
