70mai A800SE Dash Cam Product Description
The 70mai A800SE Dash Cam is a cutting-edge 4K dual-channel dash camera system designed for drivers seeking superior road safety and evidence recording. Released in 2023, this compact device features a front camera with Sony STARVIS 2 IMX678 sensor capturing ultra-HD 4K video at 30fps (3840×2160) and a rear camera at 1080p, providing crystal-clear footage in low-light conditions thanks to its f/1.8 aperture and HDR technology. The 140° wide-angle front lens and 130° rear lens minimize blind spots, while the 5.88mm ultra-thin design (1.5 x 3.9 x 1.8 inches, 3.2 oz) ensures discreet windshield mounting with 3M VHB tape. Powered by the Ambarella CV25 main chip, it supports ADAS (Advanced Driver Assistance Systems) features like lane departure warning, forward collision warning, and moving vehicle detection, alerting via voice prompts. The 128GB built-in storage (expandable to 256GB via microSD) holds up to 40 hours of footage, with loop recording overwriting old files automatically. Wi-Fi 6 connectivity enables app-based live view, download, and settings adjustment from iOS or Android devices. The supercapacitor replaces traditional batteries for better heat resistance (-4°F to 158°F), ensuring reliability in extreme temperatures. Optional GPS module adds speed and location data to videos.
