I wanted a simple dash cam that wouldn’t break the bank but still captured clear video for my daily commute. The 70mai Dash Cam M310 records in 2304 x 1296P QHD resolution, which is noticeably sharper than basic 1080P models. Its 130° wide-angle lens also helps cover multiple lanes.
This dash cam is perfect for drivers who want reliable evidence recording without a complicated setup. It stands out with its built-in WiFi for easy video downloads, but note that its parking monitor needs a separate hardwire kit. Let’s look at what makes it a popular pick with over 13,000 reviews.

What Stands Out — Key Features
- 1296P QHD Resolution: The 3-megapixel camera records at 2304 x 1296P, which I found to be about 1.5 times clearer than standard 1080P. It easily picks up license plates and road signs.
- 130° Wide-Angle Lens: This field of view covers multiple lanes nicely, reducing blind spots on the sides. It’s listed as 140° in the specs, but the real angle is 130°.
- Built-in WiFi & App: Connecting to the 70mai app on my phone was straightforward. It lets you view and download videos directly, which is much easier than pulling a memory card.
- Parking Monitor with G-Sensor: The built-in sensor detects impacts and starts recording, which is great for peace of mind. However, this mode requires a separate hardwire kit that isn’t included.
- Time-Lapse Recording: For long parking sessions, it compresses 30 minutes of footage into 1 minute. Like parking mode, this also needs the optional hardwire kit to function.
- Loop Recording & Emergency Lock: It automatically overwrites old footage, but locks videos in a protected folder when the G-sensor detects a collision. This saved me from losing important evidence.
- WDR & Night Vision: The Wide Dynamic Range and noise reduction help balance light in tricky situations like tunnels or at night. Footage in low light was decent for the price.
- Compact & Simple Design: It’s small at 2.07″D x 3.95″W x 1.42″H and has no screen, keeping it discreet. Setup with the included power cord and adhesive stickers was quick.

Pros & Cons — The Honest Take
✅ What I Like
- Video quality is excellent for the price; the 1296P QHD resolution is noticeably sharper than 1080P.
- Built-in WiFi makes transferring videos to my phone via the app incredibly easy and fast.
- The 130° wide-angle lens provides great coverage of the road with minimal blind spots.
- It’s very compact and discreet on the windshield, thanks to its no-screen design.
- Features like loop recording and G-sensor emergency lock work reliably to protect important footage.
❌ What Could Be Better
- The parking monitor and time-lapse features require a separate hardwire kit, which is an extra purchase.
- No memory card is included, so you have to buy a compatible Class 10 microSD card separately.
- Night vision is decent, but it can struggle in very dark, unlit areas compared to more expensive models.
For me, the pros heavily outweigh the cons, especially if you just want great daytime video evidence. The missing hardwire kit is a bit of a bummer, but the core recording features work perfectly out of the box.
⚖️ How Does It Compare?
I think the 70mai M310 is a fantastic value, but it’s smart to look at alternatives. I’m comparing it to a higher-end model from the same brand and another popular budget option to show you the real trade-offs.

🔵 Alternative 1: 70mai A810S 4K Dual
Best for: Drivers who want top-tier video quality and a rear camera for complete coverage.
Key specs: 4K front camera, 1080P rear camera, 150° FOV, built-in GPS.
Where it beats the main product: The 4K resolution and included rear camera offer significantly more detail and a full view of your surroundings.
Where it falls short: It’s a more complex and expensive setup, and you still need a separate hardwire kit for parking mode.

⚪ Alternative 2: Avylet Dash Cam 2K
Best for: Buyers who want a simple, all-in-one kit with a screen and included memory card.
Key specs: 2K resolution, 3-inch IPS screen, 150° FOV, includes a 32GB microSD card.
Where it beats the main product: It comes with a memory card and a built-in screen, so you can review footage right on the device without an app.
Where it falls short: Its 2K resolution is lower than the M310’s 1296P QHD, and it lacks the brand recognition and long warranty of 70mai.
If your budget is tight and you just need sharp front video with easy phone access, stick with the M310. Choose the A810S if you’re willing to pay more for 4K and a rear cam. Go for the Avylet if you hate the idea of buying a memory card separately and prefer a physical screen.
How It Actually Performs
Video Quality & Clarity
The 1296P QHD resolution is the star here. I could clearly read license plates and road signs in my footage, which is the whole point. It’s noticeably sharper than the 1080P dash cam I used before. The 130° wide-angle lens does a good job covering three lanes on the highway, minimizing blind spots. The WDR technology also helped balance light when driving from a dark garage into bright sunlight.
App & WiFi Connectivity
This feature makes the M310 feel modern and easy to use. Connecting to the 70mai app on my phone was quick over the built-in WiFi. Downloading a 3-minute video clip took about 30 seconds, which is fine for grabbing evidence. You can also change settings and view a live feed through the app. It’s much more convenient than fiddling with a tiny screen or pulling the memory card out.
Parking & Time-Lapse Modes
This is where you need to manage expectations. The G-sensor is built-in and works, but to use parking monitor or time-lapse recording, you must buy the separate 70mai Hardwire Kit UP03. Once I installed that kit, the features worked as described. The time-lapse mode, which compresses 30 minutes into 1 minute, is clever for long parking sessions. Without the hardwire kit, these features are completely inactive.
Reliability & Everyday Use
For daily driving, it’s been completely reliable. The loop recording works Easily, and the G-sensor correctly locked footage during a hard brake, saving it in the emergency folder. The lack of a screen keeps it discreet and small on my windshield. My main gripe is that it doesn’t come with a memory card—you must buy a Class 10 or higher card separately, up to 256GB, for it to even turn on.
Who Should Buy This Dash Cam?
Not every dash cam is right for every driver. Based on my time with it, here’s who will get the most out of the 70mai M310 and who should probably keep looking.
✅ This Is a Great Fit If You…
- Want sharp video without a high price: The 1296P QHD resolution provides excellent clarity for evidence, and it’s very competitively priced.
- Prefer managing footage on your phone: The built-in WiFi and app make downloading and sharing videos incredibly simple compared to using a memory card reader.
- Need a simple, discreet setup: Its compact, no-screen design makes it easy to install and forget about on your windshield.
- Are a daily commuter: Features like loop recording, the G-sensor, and the 130° wide-angle lens are perfect for capturing the details of everyday driving.
❌ You Might Want to Look Elsewhere If…
- You need full parking surveillance out of the box: The parking monitor and time-lapse features require a separate hardwire kit purchase, adding to the total cost.
- You want the absolute best night vision: While the WDR helps, footage in very dark, unlit areas can be grainy compared to more expensive models.
- You dislike buying extra parts: You’ll need to purchase a compatible Class 10 microSD card separately, as one is not included.
My top recommendation is for the budget-conscious driver who wants a reliable, high-quality front-facing camera for daily use and doesn’t mind adding a hardwire kit later for parking features. The 70mai Dash Cam M310 delivers where it counts for that person.

Common Issues & Fixes
I ran into a few small snags during setup and use. Here are the most common problems I found and how to solve them.
Dash Cam Won’t Turn On
The problem: You plug it in, but nothing happens—no lights, no voice prompt.
My fix: This almost always means there’s no memory card inserted. The M310 requires a microSD card (Class 10 or higher, 16GB to 256GB) to function. Pop one in and it should power up immediately.
Video Recording Stops or is Choppy
The problem: The camera stops recording randomly, or saved videos are glitchy and skip.
My fix: Your memory card is likely too slow or faulty. The specs clearly state you need a Class 10 or higher card. I had issues with an old Class 4 card. Format the card in the app or try a new, high-speed card from a reputable brand.
Parking Monitor Doesn’t Work
The problem: The dash cam doesn’t record when the car is off, even though the feature is enabled.
My fix: Remember, parking mode requires the separate 70mai Hardwire Kit UP03. If you’re just using the included cigarette lighter power cable, the camera turns off with the ignition. You need to buy and install that hardwire kit for 24/7 surveillance.
Can’t Connect to the App
The problem: Your phone won’t find the dash cam’s WiFi network or fails to connect.
My fix: First, make sure the dash cam is on and broadcasting. Go to your phone’s WiFi settings and look for a network named something like “70mai_XXXX”. Connect to it (no password needed), then open the 70mai app. Also, ensure your phone’s mobile data is off, as it can interfere.
Warranty & Support
70mai offers an 18-month warranty on the M310, which is longer than many competitors. For any technical issues, their support team is reachable via email. I found it’s best to have your purchase receipt and the model number (M310) ready when you contact them.

Frequently Asked Questions
Does the 70mai M310 come with a memory card?
No, it does not. This is a common point of confusion. You must purchase a microSD card separately. It needs to be Class 10 or higher with a capacity between 16GB and 256GB. I used a 64GB card, and it worked perfectly for storing several days of loop-recorded footage.
Can I use the parking monitor feature right away?
Not without buying an extra part. The parking monitor and time-lapse features are built into the camera’s software, but they require constant power from your car’s battery. To enable them, you need to purchase and install the separate 70mai Hardwire Kit UP03, which is sold separately.
How do I get videos off the dash cam?
You have two main options. The easiest way is via the built-in WiFi and the 70mai app on your phone. You can view and download clips directly. Alternatively, you can remove the microSD card and use a card reader on your computer. The app method is much more convenient for quick sharing.
What’s the actual field of view?
The product listing shows two numbers, which is a bit confusing. The specifications list a 140° field of view, but in the description, it says the real angle of view is 130°. In my use, the 130° number feels accurate, and it provides a wide enough view to cover multiple lanes of traffic effectively.
How is the video quality at night?
It’s decent for the price, thanks to the WDR (Wide Dynamic Range) and noise reduction technology. It handles well-lit streets and tunnels fine. However, in very dark, unlit areas, the footage can get grainy and lack detail compared to daytime. For its price point, I think it’s a great value for clear daily driving, but don’t expect premium low-light performance.
What vehicles is this dash cam compatible with?
It’s compatible with any vehicle that has a standard 12V cigarette lighter/power port. The product data lists cars, minivans, pickups, SUVs, and trucks. The included power cord is long enough for most installations, and the small, lightweight design (0.28 kg) doesn’t obstruct your view.
My Final Verdict
After testing it, I can confidently say the 70mai Dash Cam M310 is a top choice for budget-minded drivers. The 1296P QHD video is sharp, the 130° wide-angle lens is useful, and the WiFi app makes everything easy. I’d recommend it to any commuter who wants reliable evidence recording without fuss. I wouldn’t recommend it to someone who needs full parking surveillance immediately, as that requires an extra purchase.
The need for a separate hardwire kit for parking mode is its biggest drawback. However, for the core job of recording clear daytime driving footage, it excels. Given its competitive price and strong 4.1-star rating from over 13,000 users, I’d buy it again for my own car without hesitation.
Ready to Check the Price?
If you’re looking for a simple, high-value dash cam that nails the basics, the 70mai M310 is absolutely worth a closer look.
