70mai A900 Ultra Set 4K Dash Cam with Front and Rear

Dual True 4K HDR Front & Rear
Equipped with dual STARVIS 2 IMX678 image sensors, the A900 Ultra records True 4K HDR footage from both the front and rear cameras, capturing sharp license plates, road signs and driving details in every direction. Advanced LVDS digital transmission helps preserve the original rear-camera image quality with stable, low-latency and interference-resistant transmission.

Flagship Day & Night Imaging
Night Owl Vision 2.0 enhances nighttime recording with improved noise reduction, balanced exposure and glare suppression for clearer details in challenging low-light conditions. Scheduled HDR, customizable color and contrast settings, intelligent image processing and manual EV adjustment give you greater control over image quality across daylight, tunnels, bright headlights and nighttime driving.

Supercapacitor for Reliable Performance
Built with a durable supercapacitor instead of a conventional lithium battery, the A900 Ultra is designed for greater durability and reliable performance in demanding vehicle environments. The dash cam supports an operating temperature range from -20°C to 70°C, making it well suited for both hot summers and cold winter conditions while providing dependable long-term use.

Buffered Emergency Recording
The A900 Ultra can preserve footage from before an incident and continue recording afterward, helping capture a more complete sequence of events. Depending on the selected loop-recording duration and when the incident occurs, the buffer can capture up to 180 seconds before the event plus 30 seconds afterward, with important footage saved in the dedicated Emergency Video folder.

GPS, Wi-Fi 6 & English Voice Control
Built-in GPS records key driving information such as vehicle location, speed and route data for easier trip review. Dual-band Wi-Fi 6 supports 5GHz and 2.4GHz connections, with download speeds of up to 45MB/s for faster access to large 4K video files. English voice control lets you perform common functions hands-free, helping you keep your eyes on the road and your hands on the wheel.

Smart Parking Surveillance
The A900 Ultra supports front-and-rear collision detection, AI motion detection, pre-recording and dual-channel time-lapse recording to capture important events around your parked vehicle. Its intelligent parking functions help preserve footage from both directions and provide a more complete view of incidents that occur while the car is unattended. A compatible 70mai Hardwire Kit is required for parking surveillance and is sold separately.

Optional 4G Connectivity & Remote Access
Expand the A900 Ultra with a compatible 70mai 4G Hardwire Kit to access supported remote features through the 70mai App, including vehicle monitoring, event notifications, location services and cloud-connected functions. Available features vary depending on the 4G Hardwire Kit and service plan; certain advanced functions may require a compatible newer-generation 4G kit and activation of additional or paid 4G services. 4G Hardwire Kit is sold separately.
Note: Both the front and rear cameras feature IMX678 sensors. However, slight differences in image quality may occur due to varying lighting conditions, window tinting, and windshield reflections. Adjusting the color settings may help improve image consistency. If needed, a CPL filter (ASIN: B0FB11RMXB) can also be purchased separately to help reduce glare and improve image clarity.
