70mai Smart Dash Cam 4K A800 Built-in GPS ADAS Real 4K Camera UHD Cinema-quality Image 24H Parking Monitior SONY IMX415 140FOV
Dual-vision with the Cinema-quality Video
Combined the optional rear cam, every important detail in the front or rear of the vehicle can be recorded clearly to provide irrefutable video evidence or capture the landscape along your journey with cinema-quality video.
Up to 4K Resolution with 140°FOV
Built around a powerful Sony IMX 415 CMOS image sensor, the A800 dash cam records 4K UHD videos with a wide-angle 140° FOV.
Super Night Vision with 3D DNR
The A800 achieves stunning video and vivid, clear images even in low-light conditions using a 3D DNR (Dynamic Noise Reduction) tech, F/1.8 aperture lens and a smart algorithm that significantly reduces image noise and automatically adjusts the exposure balance. 
Boosted Driving Safety with ADAS
The A800 is more than just a reliable dash cam. When you start the car, A800 automatically begins recording and enables the ADAS (Advanced Driver-Assistance System) that will assist you while driving with lane-departure and forward collision warnings that help you avoid accidents.
GPS Built-in
More functions are coming soon.
(This will be obtained through a firmware upgrade)
In-car Guardian for 24/7 Protection
With A800 4k dash cam, the protection doesn’t stop when you leave your car. After parking, the Parking Mode is automatically activated. Using a 3-axis gravity sensor, A800 can detect any hit-and-run collision and immediately begin recording to capture valuable video evidence.
Loop Recording & Evidence Protection
The A800 records video on a loop and stores it locally on a Micro SD memory card (up to 128GB supported) while driving. This ensures that in the event of an accident, the video evidence will be captured and then safely secured from overwriting. 
In-app Access & Instant Share
No network is necessary to connect your smartphone with A800. It seamlessly connects using its own Wi-Fi for full instant access to stored videos. The dash cam also acts as a digital camera, controlled with your phone to capture any picture or view along your route. Share memories of every special road trip fast and easy online!

Haven’t installed or used the product,however it looks good. There is definitely an improvement opportunity with rear camera packaging and enhancing the hardwire kit (with fuses). Shipment was around 4 days to Invercargill which is pretty good.

While I just checked that it works, there is not enough time to install and test. I will try to complement the review later. Until I say that I did not find how to display the current speed on the whole screen.
