Features and benefits

Why I love 70mai A810S NOVATEK

• Dual Sony STARVIS 2 Sensors (IMX678 + IMX662) provide an unparalleled leap in image quality, ensuring superior day and night vision with higher clarity, better color accuracy, and significantly more balanced exposure. The front camera boasts an F1.7 aperture and a 146° Field of View (FOV), while the optional rear camera (RC24) features an F1.55 aperture and a 130° FOV, capturing a wide and detailed perspective of the road ahead and behind, which is crucial for comprehensive incident recording.
• Dual-Channel HDR Recording, with front 4K HDR and rear 1080P HDR, delivers maximum road coverage and exceptional image clarity. This technology enhances color accuracy and provides a significantly improved balance of exposure levels, ensuring that critical details like license plates are clearly visible even in challenging lighting conditions, from bright sunlight to deep shadows.
• The Smart 4K HDR Vision, powered by MaiColor Vivid+ Solution and ROI Algorithm, intelligently adapts to changing light conditions, maintaining vivid and balanced frames. The ROI (Region of Interest) Algorithm specifically focuses on capturing crucial details such as license plates with precision and efficiency, providing reliable evidence when it matters most.
• Equipped with a Supercapacitor for Power, the A810S offers enhanced safety and reliability compared to traditional batteries. This component provides better thermal resistance, allowing the dash cam to operate stably in extreme temperatures ranging from -10℃ to 60℃, boasts a long cycle life, and is eco-friendly. This ensures consistent performance and extended device longevity, reducing the risk of battery-related issues.
• The Built-in GPS and ADAS (Advanced Driver-Assistance Systems) significantly enhance driving safety and convenience. The integrated GPS accurately captures speed, time, and precise coordinates, which are seamlessly logged for review in the 70mai App, serving as irrefutable proof of travel and aiding in route optimization. The ADAS system expands safety alerts to include lane departure, forward collision, forward vehicle start, pedestrians, and cyclists, proactively helping drivers avoid potential hazards and providing added peace of mind.
• Night Vision Reinvented with 70mai Night Owl Vision and 70mai Lumi Vision technologies ensures crystal-clear recording both while driving and when parked. Night Owl Vision enhances exposure, reduces noise, and controls glare for superior night driving footage, while Lumi Vision extends exposure and boosts ISO to achieve daylight-level clarity even in pitch-black parking environments, offering comprehensive surveillance around the clock.
• The Buffered Emergency Recording feature is a critical safety net, capturing crucial footage up to 3 minutes before, during, and 30 seconds after an event. These clips are automatically saved in an exclusive «Emergency video» folder, preventing them from being overwritten by regular loop recordings. This functionality is invaluable for protecting against insurance fraud and false accusations, securing vital evidence when incidents occur.
• G-Sensor Collision Detection instantly detects sudden collisions or hard braking, automatically locking and saving the relevant footage to prevent overwriting. This ensures that essential proof of an incident is secured without manual intervention. For this feature to function, the 70mai Hardwire Kit UP03/UP04/UP06 is required and sold separately.
• Time-Lapse Recording efficiently captures long parking periods, condensing hours of footage into a short, reviewable video. This mode saves both storage space and power, making it an ideal solution for extended parking surveillance. Like G-Sensor detection, it requires the 70mai Hardwire Kit UP03/UP04/UP06, sold separately.
• AI Motion Detection, utilizing an advanced algorithm, enables the A810S to identify suspicious human activities around a parked car and automatically activate recording. This feature significantly enhances security against vandalism or theft when your vehicle is unattended. It also requires the 70mai Hardwire Kit UP03/UP04/UP06, sold separately.
• With 4G Compatibility (requiring the 70mai Hardwire Kit UP04, sold separately), the dash cam ensures uninterrupted communication with your vehicle from any location. This enables instant app alerts for collisions or unusual events during parking mode, live streaming of your car’s surroundings in real-time (even when someone else is driving), and the ability to remotely snap photos or record via the app. Additionally, the «Find My Car & Live Route Tracking» feature allows you to easily locate your vehicle in busy areas and track its live route, providing ultimate peace of mind.
• Smart Voice Control allows for hands-free operation of your dash cam using simple voice commands, currently supported in English and Mandarin only. This feature enhances driving safety by minimizing distractions, allowing you to focus on the road while managing recordings or settings.
