The 70mai T800 is a comprehensive three-channel dash cam system designed to monitor the road ahead, the vehicle's interior, and the rear view simultaneously. Both the front and rear cameras utilize the Sony STARVIS 2 IMX678 sensor to capture footage in 4K resolution at 30 FPS, while the interior camera records in 1080P. With a wide 146° to 147° field of view across all channels and an F1.7 aperture, the system ensures broad coverage and clear imagery, further enhanced by 3-channel HDR for better contrast in challenging lighting. This setup features a 3-inch IPS display and integrates Wi-Fi 6 for fast data transfers. To help with safety and documentation, it includes a built-in GPS logger and Advanced Driver Assistance Systems (ADAS). The device manages extreme temperatures from -10°C to 60°C thanks to a combination of a supercapacitor and a button cell battery, while a MicroSD slot supports storage up to 512GB. For those needing constant security, the system offers 24H parking surveillance and AI motion detection. It also supports buffered emergency recording for up to 3 minutes and voice control in several languages. The main black unit weighs 90g and connects via USB Type-C, making it a practical choice for drivers who want full-circle visibility and 4G compatibility when paired with a separate hardwire kit.
