The dual-channel dash cam deal includes a rear camera and a 64GB card, but our testing reveals some trade-offs at this sub-$100 price point.
If you’ve been shopping for a dash cam lately, you already know the drill: decent front-facing 4K units start around $100, and adding a rear camera plus memory card can easily push you past $150. That’s what makes Amazon’s latest limited-time promotion on the 70mai Dash Cam 4K A810 Lite dual-channel bundle so eye-catching.
Right now, the full kit — main 4K front shooter, RC21 1080p rear camera, and a 64GB microSD card — is selling for **$89.95**. That’s a 40 percent discount from the standard $149.99 list price. According to Amazon’s sales tracker, the deal has already moved over 2,000 units in the past month alone, so this isn’t some obscure clearance item nobody wants.
But before you smash that buy button, let’s talk about what you’re actually getting — and where this budget-friendly bundle cuts corners.

What’s in the box (and why it matters)
The A810 Lite isn’t 70mai’s flagship model — that honor goes to the non-Lite version with Sony STARVIS 2 sensors. But for $90 including a rear cam and storage, expectations need to be realistic.
The front camera captures 4K resolution (3840×2160) using an IMX415 sensor. During our hands-on testing, daytime footage came out impressively sharp. License plates remained readable at reasonable distances, and the 140° wide-angle lens did a solid job covering the road ahead without introducing excessive fisheye distortion.
Where things get interesting is the build quality. Instead of the volatile lithium-ion batteries found in many cheap dash cams — which can swell, leak, or even catch fire during hot summer months — 70mai opted for a supercapacitor. This component is rated to survive cabin temperatures up to 85°C (185°F). If you live somewhere with real summers (Texas, Arizona, or frankly anywhere south of Canada), that’s a meaningful durability upgrade.
Connectivity also gets a boost. The A810 Lite supports 5GHz Wi-Fi 6, which made transferring a 2GB video file to the 70mai smartphone app take about 45 seconds in our tests. Older 2.4GHz-only cams can take two to three minutes for the same clip. That’s the kind of quality-of-life improvement you don’t appreciate until you’re standing in a parking lot waiting for footage to save.
The honest truth about night recording
Here’s where the “Lite” naming starts to make sense.
The front camera uses HDR night vision, and in well-lit urban environments, it performs adequately. Streetlights, headlights from oncoming traffic, and ambient store lighting all get balanced reasonably well. On completely unlit residential roads, exposure mapping remains respectable — you won’t mistake it for a $400 Thinkware, but you’ll see enough detail to understand what happened in a collision.
However, activating dual-channel recording (front + rear simultaneously) forces the front camera to drop from 30 frames per second down to roughly 24–25 fps. That doesn’t sound like a huge difference, but on highways with fast-moving traffic, we noticed slight motion blur on passing vehicles. License plates in adjacent lanes became hit-or-miss. If you do most of your driving on crowded interstates, that’s worth thinking about.
The rear RC21 camera is a bigger compromise. It tops out at 1080p, and its low-light performance is… not great. Headlight glare from trailing vehicles washes out details, and digital noise creeps in aggressively once the sun goes down. During a rainy night test, the rear camera turned tail lights into amorphous red blobs. It’ll still prove who rear-ended whom, but don’t expect to read plates from behind.

Who should actually buy this deal?
At $89.95 bundled with a 64GB card (which retails for $10–15 on its own), the A810 Lite is a compelling entry point for three types of drivers:
- Budget-conscious commuters who want front and rear coverage without spending $200+. Even with the rear camera’s nighttime limitations, having any rear footage is better than none.
- Hot-climate drivers who need a supercapacitor-based camera. Lithium-ion batteries in cheap dash cams fail prematurely in heat. This one won’t.
- First-time dash cam buyers who want to test the waters. The 70mai app is user-friendly, Wi-Fi 6 transfers are painless, and the voice control (“Take photo,” “Turn on audio”) actually works reliably.
Who should skip it? Night owls who frequently drive on unlit rural roads, or anyone who needs crystal-clear rear plate capture after dark. Also, if you’re already invested in the STARVIS 2 ecosystem (like the Viofo A229 Pro), stepping down to the IMX415 will feel like a downgrade.
How long will this price last?
Amazon’s listing doesn’t specify an exact expiration date, but “limited-time deal” typically means anywhere from 24 hours to a week. With over 2,000 units sold last month, inventory could tighten quickly — especially once deal aggregators pick this up.
The standard price fluctuates between $120 and $150 depending on Amazon’s algorithmic pricing. At $89.95, this is the lowest we’ve tracked since the A810 Lite launched.
Final verdict
No dash cam under $100 with front and rear cameras is perfect. The 70mai A810 Lite bundle doesn’t pretend to be. You’re trading some nighttime rear resolution and a few frames per second for a heat-resistant design, modern Wi-Fi, and a price that undercuts pretty much everything else in its class.
If those trade-offs work for your driving environment, this deal is a genuine bargain. Just don’t expect miracles from that rear camera after sunset.
