When it comes to capturing clear, reliable footage of your journeys, the 70mai A800S dash cam delivers true 4K Ultra HD resolution using a Sony IMX415 sensor. This flagship camera from 70mai is designed to provide vivid, sharp video, making it easier to read number plates, road signs, and details even in challenging light. Starting your engine activates the camera, so you can drive with the confidence that every mile is recorded. Whether you are a daily commuter, a fleet driver, or someone who values security on the road, this dash cam offers a practical, data-rich recording solution that prioritises clarity and intelligent safety features.
Core Recording Technology
At the heart of the A800S is a combination of high-end sensor and optics engineered for real 4K video. This section covers the key components that affect image quality and low-light performance.
Sony IMX415 Sensor
The dash cam uses a Sony IMX415 sensor, which is known for its ability to capture detailed, true 4K images. This sensor provides a higher dynamic range and better colour accuracy than standard sensors, ensuring that footage remains clear in varied lighting conditions from bright sunlight to twilight.
7-Layer Glass Lens with F1.8 Aperture
A precision 7-layer glass lens with an F1.8 aperture works with the sensor to gather more light. The large aperture helps improve low-light performance, while the multi-layered glass design reduces distortion and glare. This combination delivers sharp images across the frame, especially during night driving.
Night Vision and 3D DNR
The A800S includes 3D Dynamic Noise Reduction technology, which minimises image noise in low-light scenes. This results in cleaner, more usable footage after dark, with better clarity on moving objects and dimly lit environments. The manufacturer states a 3.3x improvement over traditional night vision systems.
Safety and Driving Assistance
Beyond recording, the dash cam incorporates smart features that help you stay aware of your surroundings. These systems are designed to provide real-time alerts without being distracting.
ADAS System with Voice Alerts
The Advanced Driving-Assistance System uses the camera to detect lane markings and the vehicle ahead. If you drift out of your lane, the unit issues a voice alert. It also calculates the speed and distance of the car in front, warning you of potential collisions. These alerts are spoken in real-time, helping you react promptly.
Built-in GPS and Route Tracking
An integrated GPS module records your exact location, speed, and time with each video. This data is saved locally and can be reviewed later via the 70mai app. In the event of an accident, the GPS information is essential for roadside assistance and insurance claims, as it provides precise coordinates and journey history.
24-Hour Parking Surveillance
When you park and switch off the engine, the G-sensor automatically activates if it detects a sudden tremor or collision. The camera then begins recording, capturing critical evidence around the clock. This parking mode requires the 70mai Hardwire Kit UP02 (sold separately) for constant power. You receive a notification via the app so you can check events immediately.
Connectivity and Data Management
The dash cam integrates with your smartphone and supports automatic file management to ensure you never miss a recording.
70mai App Control and Footage Sharing
The A800S connects to the 70mai app on iOS and Android via a direct Wi-Fi hotspot. From the app you can view live footage, download recorded clips, adjust settings, and receive OTA software updates. If you are involved in an incident, you can quickly share the video with your insurance provider directly from the app for a more efficient claims process. The manufacturer confirms that all data remains local and private, with no tampering or external business use.
Seamless Loop Recording
To keep recording continuously, the dash cam automatically overwrites the oldest footage when the microSD card is full. You can set video clip lengths to 1, 2, or 3 minutes depending on your preference. The unit supports microSD cards with a minimum capacity of 32GB and a read/write speed of U1 (UHS-1) and above. This ensures smooth, uninterrupted recording on every journey.
Simple Installation and Everyday Use
The dash cam is straightforward to install using the included windscreen bracket and car charger. Once set up, it starts recording automatically when the engine starts. The black, compact design fits discreetly behind the rear-view mirror. The built-in GPS and ADAS functions operate without user intervention, making it a set-and-forget device for everyday driving.
