Quick answer
If you want a proven 4K dual-channel dash cam with Sony STARVIS 2 IMX678 and 4G LTE at a lower price, the 70mai Dash Cam 4K A810 is a solid choice. If you need the latest image processing with License Plate Enhancement, Buffered Emergency Record, and a supercapacitor for extreme temperatures, the 70mai Dash Cam 4K A810S is the better upgrade. The T800 is a different model; this comparison focuses on the A810 series.
Image quality and low-light performance
Both the A810 and A810S use the same Sony STARVIS 2 IMX678 sensor, so their 4K UHD footage is sharp and detailed during the day. The key difference is in how each model processes color and low-light scenes. The A810 relies on 70mai Night Owl Vision, a self-developed HDR algorithm that delivers clear images in static and dynamic low-light situations. The A810S adds the proprietary MaiColor Vivid+ Solution™, which improves color accuracy and balance across changing light conditions, plus 70mai Lumi Vision for near-daylight visibility in pitch-black parking environments.
For most drivers, the A810’s Night Owl Vision is more than enough for night driving and parking lot recording. If you frequently park in unlit areas or want the most vivid color reproduction, the A810S’s extra image processing gives a noticeable edge.
Recording features and durability
Both dash cams support HDR Dual-Channel Recording: front 4K HDR and rear 1080P HDR, so you get full road coverage with excellent clarity. The A810S introduces License Plate Enhancement, which helps capture readable plates in challenging conditions, and Buffered Emergency Record that saves a few seconds before an impact—useful for capturing the full context of an incident. The A810S also uses a supercapacitor instead of a battery, making it more resistant to heat and cold, which is a practical advantage if you live in a region with extreme summer temperatures.
If you drive in hot climates or want the most comprehensive incident capture, the A810S’s supercapacitor and buffered recording are worth the extra cost. The A810 remains a reliable performer for moderate climates and standard recording needs.
Connectivity and smart features
Both models support 4G LTE connectivity, allowing remote live view, parking monitoring alerts, and GPS tracking through the 70mai app. The A810S also includes an Advanced ROI (Region of Interest) Algorithm, which intelligently focuses on key areas like license plates or road signs, making playback review more efficient. The A810 lacks this feature but still offers robust app integration and cloud connectivity.
For users who frequently review footage to capture specific details, the ROI algorithm on the A810S saves time. If you mainly use the dash cam for insurance evidence and occasional playback, the A810’s standard app features are sufficient.
Trade-offs at a glance
- Image processing: A810 uses 70mai Night Owl Vision for solid low-light clarity. A810S adds MaiColor Vivid+ Solution™ and Lumi Vision for better color accuracy and near-daylight parking visibility. Choose A810S if color fidelity and pitch-black parking matter most.
