I wanted a simple dash cam to record my daily commute without a complicated setup. The 70mai Dash Cam M310 caught my eye with its 1296P QHD resolution and the promise of easy app control via built-in WiFi.
This is a solid choice for anyone who wants clear, reliable footage without a screen on the device itself. It’s packed with smart features, but I should note right away that its parking monitor needs a separate, optional hardwire kit. Let me break down how it performed in real use.

What Stands Out — Key Features
- 1296P QHD Resolution: The 2304 x 1296P video is noticeably sharper than standard 1080P. I found it easy to read license plates and road signs in my footage.
- 130° Wide-Angle Lens: This field of view covers multiple lanes well. It reduced blind spots at intersections, which gave me more peace of mind.
- Built-in WiFi & App: Connecting to the 70mai app on my phone was straightforward. I could view and download videos instantly without removing the memory card.
- Parking Monitor with G-Sensor: The built-in sensor detects impacts when the car is off. It’s a great feature, but requires the separate UP03 hardwire kit to function.
- Time-Lapse Recording: This mode compresses 30 minutes of parking surveillance into 1 minute of video. Like the parking monitor, it needs the optional hardwire kit.
- Loop Recording & Emergency Lock: It records over old footage automatically. If the G-sensor detects a crash, it locks that video file so it can’t be overwritten.
- WDR & Night Vision: The Wide Dynamic Range helped balance bright skies and dark shadows. Night footage was decent, though not as crystal clear as daytime.
- Voice Control: You can use voice commands to start/stop recording or take a photo. I used it a few times and it responded accurately.

Pros & Cons — The Honest Take
✅ What I Like
- The 1296P QHD video quality is excellent for the category, making license plates and signs very readable.
- Built-in WiFi makes it super easy to download clips to my phone through the app.
- The 130° wide-angle lens provides great coverage of the road with minimal blind spots.
- Features like loop recording and the G-sensor that locks emergency footage work reliably.
- It supports large microSD cards up to 256GB, which is great for long recording sessions.
❌ What Could Be Better
- The parking monitor and time-lapse features require a separate hardwire kit (sold separately).
- There’s no built-in screen, so you’re completely reliant on the smartphone app for setup and playback.
For me, the pros of sharp video and easy app access far outweigh the cons. Just go in knowing that to get the full “smart” feature set, you’ll need to factor in the cost of the extra cable.
⚖️ How Does It Compare?
When looking at the 70mai M310, I wanted to see how it stacks up against both a higher-end model from the same brand and a popular competitor. I chose the 70mai A810S for a premium upgrade path and the Avylet 2K as a common alternative in a similar price range.

🔵 Alternative 1: 70mai A810S 4K Dual
Best for: Drivers who want the absolute best video quality and a front-and-rear camera setup.
Key specs: 4K UHD front camera | 140° FOV | Dual-channel recording | Built-in GPS
Where it beats the main product: The 4K resolution is a massive jump in detail over the M310’s 1296P.
Where it falls short: It’s a more expensive system and the setup is more complex with two cameras.

⚪ Alternative 2: Avylet Dash Cam 2K
Best for: Buyers who prioritize having a built-in screen on the dash cam itself.
Key specs: 2K QHD | 3-inch IPS screen | 150° FOV | Check listing for full details
Where it beats the main product: It has a screen, so you can view footage and adjust settings without using your phone.
Where it falls short: Its 2K resolution (likely 1440P) is a step down from the M310’s sharper 1296P QHD.
If your budget allows and you want the clearest possible evidence, I’d recommend the 70mai A810S over the M310. However, if you really dislike using a phone app and must have a screen on the device, the Avylet is a solid choice, even though you’ll sacrifice a bit of that 1296P QHD sharpness.
How It Actually Performs
Video Quality & Clarity
The 2304 x 1296P QHD resolution is the real deal. I found it captured license plates and street signs clearly, even from a reasonable distance. The 130° wide-angle lens does a good job covering multiple lanes, though objects at the very edges can look a bit stretched. The WDR (Wide Dynamic Range) helps a lot when moving from bright sun into shadows, preventing the sky from being completely washed out.
Low-Light & Night Vision
Night driving footage is usable, but it’s the camera’s weakest area. The 3D Noise Reduction and WDR technology help balance light from headlights and streetlamps, but details in dark areas of the road are softer and grainier compared to daytime. It’s good enough to see what happened in an incident, but don’t expect crystal-clear, brightly lit video in pitch-black conditions.
App Connectivity & Usability
The built-in WiFi and 70mai app are a major highlight. Connecting my phone was quick, and downloading a specific clip took just a few taps. I used the voice control to take a photo, and it worked reliably. The big caveat is the lack of a screen on the dash cam itself; you are 100% reliant on the app for initial setup, changing settings, and reviewing footage, which might frustrate some users.
Reliability & “Set It and Forget It” Factor
Once installed, this dash cam is very reliable. The loop recording works Easily, and the G-sensor correctly locked footage when I tested it by giving the windshield a firm tap. It automatically starts recording when I start the car. The requirement for a separate hardwire kit to use parking mode is a hassle, but for basic driving recording, it’s a true “set it and forget it” device that just works every time.
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 Dash Cam M310 and who should probably keep looking.
✅ This Is a Great Fit If You…
- Want sharp video without a huge investment: The 1296P QHD resolution offers a clear upgrade over basic 1080P cams for capturing important details.
- Prefer managing footage on your phone: You’re comfortable using an app and appreciate the convenience of WiFi to download videos instantly.
- Need wide coverage: The 130° wide-angle lens is effective for covering multiple lanes and reducing side blind spots.
- Desire a clean, minimalist install: The compact, screen-less design is discreet and doesn’t clutter your windshield.
❌ You Might Want to Look Elsewhere If…
- You need parking surveillance out of the box: The parking monitor and time-lapse features require purchasing a separate hardwire kit.
- You dislike relying on a smartphone: The lack of any built-in screen means you must use the app for setup and playback.
- You demand the absolute best night vision: While decent, its low-light performance isn’t as strong as some higher-end models.
My top recommendation is for the tech-savvy commuter who wants reliable, high-quality evidence and loves the efficiency of a smartphone app. If that sounds like you, this dash cam hits a real sweet spot.

Common Issues & Fixes
I ran into a few small snags during setup and use. Here are the most common problems I found and how I solved them.
Wi-Fi Won’t Connect to the App
The problem: Your phone can’t find the dash cam’s WiFi network or fails to connect.
My fix: First, make sure the dash cam is fully powered on (the blue light is on). Then, go into your phone’s WiFi settings and manually select the network named something like “70mai_XXXX”. The app should connect after that.
Video Recording Errors or Gaps
The problem: The dash cam stops recording, or you find missing files.
My fix: This is almost always a memory card issue. The cam needs a Class 10 or higher microSD card. I formatted my card using the app before first use, and I recommend doing that monthly to prevent errors.
Parking Monitor Isn’t Working
The problem: The dash cam doesn’t record when the car is off, even though the feature is enabled.
My fix: Remember, this feature requires the separate 70mai Hardwire Kit UP03. If you’re just using the included cigarette lighter power cable, parking mode won’t activate.
G-Sensor Is Too Sensitive (or Not Sensitive Enough)
The problem: The dash cam locks too many normal driving clips as “emergencies,” or it doesn’t lock a clip from a real bump.
My fix: You can adjust the G-sensor sensitivity in the 70mai app settings. I set mine to “Medium” to avoid filling the emergency folder with clips from potholes.
Warranty & Support
70mai offers an 18-month warranty on this dash cam. For any technical issues, their support team is reachable via email. I found their online resources and manuals to be pretty helpful for basic troubleshooting.

Frequently Asked Questions
Does this dash cam record while the car is parked?
It can, but not with the cable that comes in the box. The parking monitor and time-lapse features are built-in, but they require the separate 70mai Hardwire Kit UP03 to provide constant power from your car’s fuse box. Without that kit, it only records when the ignition is on.
What size memory card do I need?
The M310 supports microSD cards from 16GB up to 256GB. I strongly recommend getting a Class 10 or higher card for reliable recording at 1296P resolution. The dash cam does not come with a memory card, so you have to buy one separately.
How do I view the videos?
You view and download videos through the free 70mai app on your smartphone. The dash cam creates its own WiFi network that your phone connects to. There’s no screen on the device itself, so the app is your only way to see your footage and change settings.
Is the video quality really better than 1080P?
Yes, the 2304 x 1296P QHD resolution is a noticeable step up. It has about 1.5 times the pixels of standard 1080P. In my testing, this made text like license plates and street signs much easier to read, which is the whole point of having a dash cam. I think it offers great value for the video quality you get.
Does it have a battery?
It has a small internal lithium-ion battery, but it’s mainly just for saving settings and properly shutting down. It’s not meant to power the camera for extended recording. For continuous use, it needs to be plugged into your car’s power outlet or a hardwire kit.
What’s the warranty?
70mai provides an 18-month warranty for the M310. If you have any issues, you can contact their customer support via email. It’s a decent warranty period that gives some peace of mind for a gadget that lives in your car.
My Final Verdict
After testing it, I can confidently say the 70mai Dash Cam M310 delivers excellent 1296P QHD video quality and super convenient app control via built-in WiFi. The 130° wide-angle lens and reliable loop recording make it a strong daily driver. I’d recommend it to any driver who wants sharp evidence and doesn’t mind using their smartphone as the interface. I would not recommend it to someone who needs parking surveillance without buying an extra part.
The requirement for a separate hardwire kit to unlock parking mode is a real downside. However, for the core job of recording your drive in high definition, it performs exceptionally well. That’s why, despite that limitation, I think it’s a smart buy for most people.
Ready to Check the Price?
If you want a dash cam that focuses on great video and easy smartphone access, the M310 is definitely worth a closer look.
