Looking for a high-quality 4K dash cam around $100? In this video I fully review the 70mai A810S dash cam, the brand new upgraded version from the A810, one of the newest STARVIS 2–powered cameras designed for sharp detail, strong night performance, and smart driving features.

I test the A810S in real-world conditions — bright daylight, night driving, rain, and parking mode — to see how it performs when it actually matters. You’ll see unedited footage samples, app controls, installation notes, and whether this camera is worth buying in 2026.

📹 Key features covered in this review:

• True 4K UHD front recording (3840×2160)
• Sony STARVIS 2 sensor for enhanced night vision
• HDR processing for balanced exposure
• Built-in GPS tracking (speed & route logging)
• ADAS safety alerts (lane departure & collision warning)
• Dual-channel support with optional rear camera
• Wi-Fi + 70mai mobile app control
• Loop recording + emergency G-sensor lock
• Buffered parking surveillance (hardwire kit required)
• Wide-angle lens for full road coverage
• Compact windshield design

I also talk about the downsides — rear camera quality, menu controls, power requirements, and whether the parking mode setup is worth the extra cost.

If you’re deciding between budget-friendly dash cam options and premium-tier products (such as those from Viofo or Nextbase), this review will help you understand exactly where the A810S positions itself in the market.

Is this the best overall 4K dash cam right now… or just marketing hype? Watch to the end for my honest conclusion.
