TL;DR Sony STARVIS 2 IMX678 front sensor · three independent DashCamTalk community reviews confirm plate legibility and 4K detail; gizmochina calls the night footage benchmark-class. Supercapacitor design (no lithium battery) addresses the heat failures documented in the predecessor A810. Trigger-only parking mode, hardwire kit sold separately. FCC/CE only · no UL/ETL electrical safety certification.
The A810S records front 4K and rear 1080P simultaneously with dual Sony STARVIS 2 sensors and an f/1.7 aperture. Three independent 2026 community reviews on DashCamTalk confirm daytime footage detail and plate legibility; night performance is similarly strong, with an owner describing usable detail on unlit backroads. The supercapacitor energy storage eliminates the battery-degradation failure mode that affected the original A810 in hot climates. Parking mode is trigger-only · AI motion detection fires a 30-second clip with no pre-event buffer; the hardwire kit (UP03 or UP05) is sold separately and required for all parking features. A firmware bug in v1.5.40ww caused audio/video gaps on full cards; the companion app is poorly rated, with documented token-expiry connectivity failures.
Drivers who want front-plus-rear 4K coverage with proven hot-climate durability · the supercapacitor design handles parked-car heat that kills lithium-battery dash cams. Skip it if a buffered parking mode is the priority; trigger-only means no pre-event footage, and the required hardwire kit adds cost. Drivers who need a reliable app experience should also consider alternatives · the app's low App Store rating reflects recurring connectivity problems.
Supercapacitor energy storage eliminates lithium thermal-runaway risk; no battery-specific disposal guidance is needed. At end of life, the unit qualifies for standard e-waste drop-off through Best Buy or municipal programs · no manufacturer take-back program is documented. Carries FCC and CE marks only; no UL or ETL independent electrical safety certification confirmed.
No · it uses a supercapacitor combined with a small button cell for power retention, not a lithium-ion battery. The supercapacitor is rated to 85°C and 500,000 charge-discharge cycles, which directly addresses the heat-related failures documented in the original A810.
No. The A810S uses trigger-only AI motion detection for parking · it records a 30-second clip when motion is detected, but there is no pre-event buffer. The A810S does include collision-triggered emergency recording (up to 3 minutes before + 30 seconds after) during driving, but this is not the same as buffered parking mode.
No. All parking mode features require a 70mai hardwire kit (UP03 or UP05), sold separately. The standard box includes a 12V cigarette lighter adapter. Third-party hardwire kits do not work with 70mai parking mode signaling · a 70mai-specific kit is required.
No. Despite carrying a Wi-Fi 6 label, the A810S operates on the 2.4GHz band only. The Wi-Fi 6 designation refers to the protocol version, not dual-band support. Real-world measured speeds are approximately 20 MB/s on 2.4GHz.
