70mai Dash Cam 4K A810 Lite Review

The 70mai Dash Cam 4K A810 Lite is a relatively affordable 4K dash cam with a 1080p rear camera and the option to add 4G connectivity with a hardwire kit for GPS tracking and remote alerts.

With a discounted price of £100 for the base kit, I have been pleasantly surprised with the overall quality of this camera, and it is a good investment for anyone looking for an affordable dash cam.

That said, the Lite name is doing some quiet work here. 70mai already sells the A810S, which uses a Sony STARVIS 2 sensor and records dual-channel at a higher frame rate. The A810 Lite sits a rung below that, and once you understand where the corners have been cut, it becomes much easier to judge whether it is the right camera for you. This review covers the design, installation, day and night footage, parking security, and the 4G features, along with how it compares to the rest of the range.

Specification

A couple of the headline numbers deserve a closer look before we move on. The front camera is listed at 4K 30fps, but that 30fps figure only applies when you run the front camera on its own. As soon as you add the rear camera and record both channels at once, which is how most people will use it, the front drops to 24fps and the rear sits at 25fps. When I checked the frame rate data in VLC, the front footage was indeed recording at 24fps rather than 30. It is not a deal-breaker, but it is worth knowing that the 30fps headline is a single-channel figure.

The other point worth flagging is the sensor. The A810 Lite does not use the Sony STARVIS 2 sensor that you get in the dearer A810S. The processor is a Novatek NT98530 paired with a more budget sensor, and that is one of the main ways 70mai has brought the price down. It still produces clean 4K, as I will come to, but it is not the same imaging hardware as the step-up model.

Unboxing and Design

The box contains the A810 Lite front unit, the RC21 rear camera, a 64GB microSD card, the USB-C power cable, the rear camera cable, cable clips, a pry tool for tucking the wiring under the trims, and the adhesive mounts. Having a memory card in the box is a nice touch at this price, since plenty of cameras leave you to buy one separately before you can record anything.

Build quality is the first sign that this is a budget product. The main unit is plasticky, and while it does not feel fragile, it lacks the more solid feel of higher-end models. The rear RC21 camera feels particularly cheap, which is the same unit 70mai ships with several of its other kits, so the corner-cutting is not unique to this set.

70mai markets the front camera as credit card sized, and on paper the 91 x 46 x 24.4 mm dimensions back that up for the footprint. In the hand, though, it feels chunkier and boxier than the marketing suggests, mainly because of the depth. It still tucks behind the rearview mirror neatly in most cars, and the small screen means it does not dominate the windscreen, but do not expect something as slim as the photos imply.

One practical limitation is the mount. Adjustment is horizontal only, so you are relying on the windscreen angle and the mount position to get the vertical framing right. In cars with a steeply raked windscreen, you may find it harder to hide the unit fully behind the mirror and still get a level shot. It worked fine in my installation, but it is a fiddlier setup than a ball-joint mount would be.

The 3.8-inch IPS display is bright and clear, and at 960 x 376 it is sharp enough to frame the camera and check footage. I left it switched on during testing, including at night, and it did not bother me. If you would rather not have a lit screen in your eyeline, you can set it to dim or switch off after a few seconds.

Installation

The physical installation of the dash cam is technically simple. You stick the mount to the windscreen, attach the camera, and wire it into the supplied USB-C adaptor that plugs into the 12V socket. If that is all you want, you can be up and running in a few minutes, and the app pulls the time, date, and location from your phone so there is very little to configure on the device itself.

It gets more involved if you use the 4G hardwire kit, because that needs to be wired into the fuse box rather than the cigarette lighter socket. You identify two suitable fuse circuits and an earth point, connect the live and switched-live leads, and ground the kit to a bolt on the chassis. This is the step that turns a five-minute job into a proper installation, and if you are not comfortable working in the fuse box, it is worth paying an installer.

The other fiddly part is routing the cables neatly around the cabin, especially the longer run to the rear camera. The included pry tool helps you tuck the wiring under the headlining and trims so nothing hangs loose. For my installation, I was deliberately lazy and left the cables loose, as I am expecting another review sample and will need to remove this dash cam afterwards. If this were a permanent install, I would take the time to hide every cable run, and the kit gives you what you need to do that.

70mai App and Settings

The 70mai app remains one of the stronger reasons to buy into the brand. It connects over Wi-Fi or Bluetooth, pulls a live view from both cameras, and lets you change settings, browse the album, download clips, and review your route on a map without taking the card out. Setup is guided by a QR code on the device, and pairing is straightforward.

On the camera itself, the menu is logical and the physical buttons make it easy to navigate while the unit is mounted. You can toggle audio recording, capture an emergency clip, adjust the parking surveillance sensitivity, set the loop length, and turn the various voice prompts on or off. Voice control supports English, Chinese, Russian, Japanese, Vietnamese, and Thai, with simple commands such as “take photo” or “turn off audio” so you can keep your hands on the wheel.

Wi-Fi 6 is the standout here for anyone who pulls footage off regularly. 70mai quotes download speeds of up to 25MB/s, and in practice a one-minute 4K clip transfers in around 30 seconds. That is a genuine improvement over the older Wi-Fi 4 cameras, which crawled along at a few megabytes per second. If you use an iPhone, the transfer process is a little slower than on Android and could do with some optimisation, but since most people only extract clips occasionally, it is not a major issue.

Performance – Driving Recordings

The default setting records video in one-minute clips, which I would leave as it is. It makes downloading any single moment you need much easier than wading through long files.

During daylight, the front camera is excellent. Number plates, the detail on cars, road signs, and pedestrians are all easy to make out, and the 4K resolution gives you plenty of room to crop in on a detail after the fact. The footage is clean and the colours are natural rather than over-processed, and the quality is high enough that you could realistically use clips for something other than evidence, such as travel footage. For a camera at this price, that is a strong result.

There are limits, as you would expect. Cars travelling the other way at speed can be hard to read, with number plates blurring as they pass, but that is true of almost every dash cam regardless of price and is down to relative speed and exposure rather than a fault of this camera. The 140-degree front field of view is good for the money and is standard for a forward-facing lens, although some pricier cameras offer a wider 180-degree cabin or front view if you want to capture more across multiple lanes.

Rear performance is adequate. Shot at 1080p, 25fps, and 130 degrees, the RC21 lets you read number plates on cars close behind you and gives you a good level of detail on anything that rear-ends you, which is the main job of a rear camera. It is not sharp enough to pull plates from a distance, and there is no rear HDR, so it is best thought of as a competent witness rather than a second high-quality camera.

Night-time footage from the front camera is surprisingly good for the price point. The f/1.55 aperture lets in a lot of light, and combined with the HDR processing and 3D noise reduction, well-lit roads and junctions come out clear with readable plates on nearby vehicles. It is not flawless, and you will see some glare and reflection from the windscreen and street lighting, but it is comfortably above what I would expect at this level. The rear camera at night is the weaker link. It is usable and will still capture the broad strokes of an incident, but the detail drops off noticeably once the light fades.

If I had to summarise the footage, the front camera punches well above its price in daylight and holds up well at night, while the rear is fine for evidence but ordinary. That is a sensible balance for a camera designed to keep costs down.

Parking Security

Parking surveillance is where the A810 Lite earns its keep as a permanent install, but it does require the hardwire kit, which is sold separately. The non-4G UP03 kit covers the basic parking functions, while the UP05 kit adds 4G. Without one of these, the camera cannot stay powered while the car is off, so the parking features are off the table on the supplied 12V adaptor alone.

With a hardwire kit fitted, you get 24-hour parking surveillance with several layers of protection. Collision detection uses the G-sensor to trigger a 30-second recording from both the front and rear cameras if the car is bumped while parked, and you get a voice alert the next time you switch the car on so you know to check the footage.

The buffered emergency recording is more sophisticated than most cameras at this price. It can capture footage from as little as 10 seconds up to 3 minutes and 10 seconds before an impact, plus 30 seconds afterwards. The buffer length follows your loop setting, which defaults to one minute but can be raised to two or three minutes if you want a longer lead-up to an event. Saved clips are locked into an emergency folder so they are not overwritten by normal loop recording.

Time-lapse recording is the option I would lean on for parking. It records continuously at 1fps and compresses every 15 minutes of footage into one minute of video, which saves a huge amount of card space and lets you scrub through hours of surveillance quickly to spot anything worth a closer look. There is also AI motion detection on the higher settings, which flags movement around the car.

One word of advice from testing. The parking sensitivity has multiple levels, and the highest setting is too eager for everyday use. On high, every speed bump and firm door close can stop recording and dump a clip into the alarm folder, which quickly becomes annoying. Knocking it down a notch or two gives you far fewer false alerts without losing the genuine ones.

70mai also markets its Lumi Vision night mode for parking, which boosts the ISO to capture footage in near-total darkness. It is aimed at dim garages and unlit streets, and while it does brighten the scene, treat it as a feature for situational awareness rather than forensic detail.

4G Connectivity – Vehicle Location, Tracking and Notifications

The 4G option is the most interesting part of the A810 Lite and is genuinely uncommon at this price. It needs the 4G hardwire kit and a data SIM, which you buy yourself from any provider. The one catch worth repeating is that the SIM must have its PIN code disabled, otherwise the kit cannot connect to the network. The simplest way to do this is to pop the SIM into a phone, remove the PIN, then move it to the hardwire kit.

Once it is connected, the camera stays reachable even when you are nowhere near the car. You can open the app and pull a live view of the front and rear cameras to see what is happening around the vehicle, check its GPS location, view the route history, and monitor the battery voltage so you know the car is not at risk of a flat. There is also a find-my-car function with walking navigation for crowded car parks, plus geo-fencing on the higher service tiers.

The feature that makes the 4G worthwhile is the instant alerting. If the car is bumped or motion is detected while parked, the camera records the event and pushes a notification to your phone or watch over the mobile network, then uploads the clip to the cloud. That last part matters, because if the camera or card is damaged in an incident, the footage is already backed up off the device. For anyone parking on the street or worried about theft and vandalism, that peace of mind is the main reason to add the kit.

The 4G features lean on 70mai’s 4G Cloud+ service, which is tiered. The Basic plan is free and includes instant alerts, find-my-car, battery monitoring, 30 minutes of live streaming per day, 15 live GPS tracks per month, and 7 days of cloud retention. The paid Standard tier costs around £2 per month and raises that to 60 minutes of live streaming, 30 GPS tracks, geo-fencing, and 15 days of retention. The Premium tier at around £3 per month gives unlimited live streaming and GPS tracking with 30 days of retention. For most people the free Basic plan covers the essentials, and you only need to pay if you want to check in on the car frequently or keep footage in the cloud for longer.

It is worth being realistic about the running costs, though. Adding the 4G hardwire kit and a data SIM, and potentially a monthly cloud subscription, turns a cheap dash cam into an ongoing commitment. Whether that is worth it depends entirely on where you park and how much you value remote monitoring.

The 70mai Dash Cam 4K A810 Lite is available on Amazon UK for £129.99 RRP, and at the time of writing it was available for £100 with the on-page voucher. The 4G Hardwire Kit is then an additional cost, sold separately, at roughly £40 to £50 depending on which version you choose.

70mai also has a couple of step-up options worth knowing about. The A810S is a 4K plus 1080p dual STARVIS 2 HDR dash cam available for £200 RRP, discounted to around £160. It uses the better Sony sensor, records dual-channel at a higher frame rate, and has a more solid build, so it is the one to look at if image quality is your priority and the extra £60 or so is not an issue. There is also the X800 with the optional UP04, an interesting 4K pan-tilt camera that can provide 360-degree coverage. The X800 on its own is £300, so it sits in a different bracket entirely.

The dash cam market is saturated, especially for affordable models, so it is hard to point to a single best alternative. What sets the 70mai cameras apart is the 4G option, since very few affordable dash cams let you add proper mobile connectivity for remote alerts and cloud backup. If that feature is on your list, the A810 Lite is one of the cheapest ways to get it. If you only care about recording quality and have no interest in remote monitoring, you could find capable 4K cameras from other brands at a similar price, and the A810S is the obvious in-house upgrade.

Overall

The 70mai Dash Cam 4K A810 Lite is a sensible budget choice that gets the important things right. The front 4K footage is excellent in daylight and strong at night, the app and Wi-Fi 6 transfers are quick and easy to live with, the parking features are more capable than the price suggests, and the optional 4G connectivity is a real point of difference for an affordable camera.

The compromises are exactly where you would expect them on a Lite model. The build is plasticky and the rear camera feels cheap, the dual-channel mode records at 24/25fps rather than the headline 30fps, the sensor is a step below the A810S, the mount only adjusts horizontally, and the parking alerts need taming on the higher sensitivity settings. None of these are dealbreakers at £100, but they are the reasons it costs what it does.

For around £100 for the base kit, I think it is a good investment for anyone after an affordable 4K dash cam, particularly if the 4G option appeals. If you want the best image quality 70mai offers and can stretch the budget, the A810S is the better camera. But as a value proposition, the A810 Lite does its job well and is easy to recommend to anyone shopping at the cheaper end of the market.
