70mai A800SE Dual Dash Cam (Front 4K + Rear 1080P) with GPS, WiFi, ADAS and 128GB microSD

If you want dash cam footage you can actually use in a dispute, the 70mai A800SE is built around two ideas: strong front clarity and coverage from more than one angle. On paper, that means a front camera recording in 4K, paired with a rear camera that can rotate to aim inside or behind your vehicle.

It’s also trying to cover the “what happens when you’re parked?” gap with 24/7 parking monitoring support, plus emergency recording that extends the timeframe around an impact. Still, it’s not a one-size-fits-all kit — some key features depend on accessories and settings, so it’s worth checking what you’re planning to run before you buy.

Key takeaways

The headline is dual recording: front in 4K UHD with a wide 140° field of view, and rear in 1080P using a rotating camera. The A800SE also bundles GPS and ADAS safety alerts, and it includes a 128GB microSD card in the pack, which saves you the extra step of picking storage.

Where it gets more interesting for day-to-day ownership is how it approaches low light and incidents. The front lens uses an F1.55 aperture with HDR and is paired with “super night vision” processing aimed at improving detail in darker scenes. For collisions, the emergency recording setup aims to capture a longer pre- and post-impact window rather than just the moment of impact.

For parking, it’s designed to work with a compatible hardwire kit (sold separately) and then use G-sensor detection and a time-lapse approach while the car is parked. If that’s the sort of coverage you care about, this model is clearly heading in that direction.

What you’ll notice in practice (a quick example)

Imagine you’re driving at night in a poorly lit street and someone pulls out suddenly. With the front camera’s HDR + F1.55 aperture approach, you’re getting a better chance of readable detail than a more basic dash cam might manage. If it involves your rear quarter as well, the rotating rear camera gives you an additional viewpoint that can be useful when you’re comparing what you saw versus what happened.

The essentials

The 70mai A800SE is a front and rear dash cam system, described as 4K+1080P dual recording. The front captures 4K video (3840×2160) with a 140° FOV, while the rear camera records 1080P and is rotatable to face inside or behind the vehicle. That flexibility can be handy if you want the rear camera aimed more deliberately, rather than stuck in one default direction.

It includes WiFi connectivity via the built-in 2.4GHz WiFi, plus app control through the 70mai App. The idea is you can adjust settings, preview footage, edit and share clips from an iOS or Android phone without repeatedly pulling the memory card.

There’s also GPS support with a 5-module satellite positioning system (GPS plus multiple constellations listed in the description). The dash cam can display driving route, speed and coordinates information in the app, and it supports offline driving tracking if GPS signal is temporarily lost.

On top of that, ADAS safety alerts are included (the description mentions support for 5 ADAS warnings). That’s useful as an assistance layer, but it’s still an alert system — not something you should treat as a substitute for careful driving.

Specs that matter before you choose

Here are the details that are most likely to affect your setup and day-to-day experience:

• 4K front recording (3840×2160) with 140° field of view
• Rotating rear camera for 1080P recording (aim inside or behind)
• Emergency recording capturing 10s–3min before impact plus 30s after, up to 210 seconds of recording time
• Loop recording to overwrite the oldest files when storage is full
• Includes a 128GB microSD card, stated recording time is about 8 hours for front camera only with 128GB
• Supports microSD up to 512GB max, with U3 or higher cards
• Built-in 2.4GHz WiFi and phone app control for previewing, editing and sharing
• GPS + multi-constellation support for route/speed/coordinates info in the app
• Parking monitoring support, including time-lapse when parked and G-sensor shock/collision detection
• 24/7 parking monitoring is described as working with a compatible Type-C hardwire kit (sold separately, UP03 or UP06 are mentioned)

It’s worth noting that parking features aren’t presented as “fully self-contained” — the hardwire kit is called out as sold separately, so if you want true 24/7 monitoring you’ll need to plan for that.

Where it shines (and where it may not)

The A800SE looks best if you want more than a basic single-lens dash cam. Dual recording (front 4K plus rotating rear 1080P) is a strong selling point when you’d rather have more context than less.

Low-light performance is another practical angle here. The F1.55 aperture lens with HDR and “super night vision” processing is specifically aimed at darker conditions, which is exactly when clarity matters most—headlights, reflective signs and night-time road markings can get messy fast.

However, if your main goal is simple recording while you drive and you don’t care about parking surveillance, you might not need to pay attention to the hardwire kit requirements or the parking monitoring modes at all. Also, emergency recording windows (pre- and post-impact) are helpful, but they’re not a guarantee of perfect capture in every scenario — the timing depends on how the trigger is handled and how the cameras are positioned.

Pros

• Dual-cam setup with front 4K and rotating rear 1080P
• Includes 128GB microSD card to get you recording sooner
• GPS support for speed/route/coordinates in the app and offline track restoration
• Emergency recording extends pre- and post-impact capture
• WiFi/app control for previewing and sharing without constant card removal
• Night-focused approach with F1.55 aperture lens and HDR

Cons

• 24/7 parking monitoring is tied to a Type-C hardwire kit sold separately
• If you only use front recording, the stated storage duration is shorter than for a full dual setup would be (so consider your expected usage)
• ADAS alerts are described generally, depending on your driving style and road type, it may be more “assist” than “must-have”

Compatibility & requirements

For 24/7 parking monitoring, the description specifies use with a compatible 70mai Type-C hardwire kit (UP03 or UP06 are mentioned). If you’re not planning to use a hardwire setup, you may only get the main driving recording experience rather than the full parking surveillance behaviour.

Also, the microSD card requirement is defined by capacity and class: it supports microSD cards from 32GB up to 512GB max, with U3 or higher cards. While 128GB is included, it can matter if you’re thinking about upgrading later.

Should you buy it?

This is a sensible buy if you want dual recording with front 4K detail, a rear camera you can rotate to match how you want the coverage framed, and extras like GPS tagging and WiFi/app control. It also makes sense if night-time clarity is a priority for your commute or regular driving routes.

You may want to skip it if your budget only stretches to basic “while I’m driving” footage and you don’t want to deal with hardwiring for 24/7 parking monitoring. It might also be a bit of overkill if you’d rather spend your effort on simpler setups than on app-based controls, GPS tracking information and ADAS alerts.

If you’re the kind of driver who likes having more than one angle during incidents, and you care about capture windows around impacts, the A800SE’s approach is the right direction — just make sure you’re comfortable with the parking monitoring requirements if that’s a key part of your decision.
