Features and benefits

Why I love 70mai M800 NT98529-E

• Exceptional 4K HDR Clarity and Advanced Night Vision: The 70mai M800 captures every detail with a stunning 4K (3840×2160) resolution and Dual HDR support, ensuring crystal-clear footage in any lighting condition. This is further enhanced by Dual STARVIS 2 Technology, utilizing the SONY Starvis 2 IMX678 imaging sensor, which provides an elite-level visual experience with ultra-high sensitivity and rich detail, even in challenging low-light environments. For dual-channel setups, the optional RC14 rear camera records in 1080P at 30FPS, delivering smooth, clear footage from both front and rear angles, ensuring no detail is missed on busy streets or open roads.
• Robust and Reliable Built-in 128GB eMMC Storage: Unlike traditional dash cams relying on external TF cards, the M800 features a built-in 128GB eMMC storage. This offers significantly faster performance and a longer lifespan, ensuring safer and more reliable recording without the common issues of video loss, errors, or the need for frequent card replacements. Your critical footage remains secure, providing a worry-free driving experience.
• Comprehensive 24-Hour Parking Surveillance: With the addition of a 70mai Hardwire Kit or 4G Hardwire Kit (sold separately), the M800 provides advanced 24-hour parking surveillance. The built-in G-sensor instantly locks collision videos, with adjustable sensitivity from 1 to 5 levels, capturing a 30-second emergency clip (2 seconds before and 28 seconds after impact) for full context. Additionally, Time-Lapse Recording efficiently compresses every 30 minutes of video, conserving memory while maintaining uninterrupted monitoring of your parked vehicle.
• Seamless 4G LTE Remote Connectivity and GPS/ADAS Integration: When paired with the 4G Hardwire Kit UP04 (sold separately), the M800 offers continuous 4G LTE connection, allowing remote access to your car from anywhere. Features include App Live Streaming to check surroundings in real-time, Instant App Alerts for emergencies, Find My Car for accurate location, and Live Route Tracking. Complementing this, the built-in GPS accurately logs speed, time, and precise coordinates, seamlessly reviewed in the 70mai App for proof of travel and route optimization. The ADAS (Advanced Driver Assistance System) further enhances safety by providing alerts for potential hazards like lane departure and front collision warnings.
• Smart Control and Efficient Data Management: The M800 integrates smart control features for user convenience. Fast downloads are possible via Wi-Fi 6 5GHz, achieving speeds up to 10MB/s, making footage retrieval quick and efficient. Voice Control, supporting English and Mandarin, allows for hands-free operation and easy access via the app. The Loop Recording feature ensures continuous recording by overwriting old footage while automatically locking critical moments and parking incidents, guaranteeing that important events are always preserved.
