Below is recorded using firmware v20201009 in H.265 2560×1440 30fps with an overall bitrate of 16.5 Mb/s with WDR on.

 

 

Final thoughts
A nice small cube design with crisp clear videos. From the price of USD69.99 (MYR285+-) can be considered a good budget 2K dashcam.

The KakaOK app is very straight forward to use. Video streaming without any lag.

The 4K resolution is considered to non-true 4K resolution as the B2K uses a 5MP sensor, not an 8MP sensor which can record in true 4K resolution.

Regarding the buffered parking mode, I didn’t get to test it out as I didn’t have a mini USB hardwire kit for the testing.
