5. Key Features Explained
5.1 Dual 4K Front + 1080P Rear Recording
The A800SE captures crystal-clear 4K (3840x2160) video from the front camera with a 140° field of view, ensuring sharp details like license plates. The 1080P rear camera provides additional coverage, recording either the interior or the rear view of your vehicle, crucial for comprehensive incident recording.

5.2 Super Night Vision with F1.55 Aperture & HDR
Equipped with an F1.55 large aperture lens and HDR technology for both front and rear cameras, the A800SE excels in low-light conditions. It processes details 16 times better than traditional cameras, balancing light and shadows to capture clear images at night, enhancing overall driving safety.

5.3 Extended Emergency Recording
The dash cam provides an extended emergency video pre-recording solution. It automatically records 10 seconds to 3 minutes before impact and 30 seconds after, capturing the entire incident timeline up to 210 seconds. These critical videos are saved in a special, protected folder to prevent overwriting.

5.4 24-Hour Parking Surveillance & G-Sensor
When paired with the 70mai UP03 Type-C Hardwire Kit (sold separately), the G-sensor detects sudden shakes or collisions while parked, automatically initiating recording. The dash cam also supports time-lapse mode for 24-hour surveillance, reducing storage space by recording at 1/30th of the normal frame rate.

5.5 Loop Recording & Ample Memory
The reliable loop recording function ensures continuous recording by automatically overwriting the oldest files when the memory card is full. This guarantees uninterrupted recording without manual deletion. The A800SE comes standard with a 128GB microSD card and supports cards up to 512GB (U3 or higher).

Equipped with a 5-module satellite positioning system (GPS + BDS + Galileo + GLONASS + QZSS), the dash cam provides precise global signal coverage for accurate location tracking. Driving routes, speed, latitude, and longitude can be monitored in real-time via the app. ADAS (Advanced Driver-Assistance Systems) actively monitors risks, offering warnings for lane departure, front vehicle collision, pedestrian collision, and cyclist collision, enhancing driving safety.
