Blueskysea B2K

Blueskysea B2K

The Blueskysea B2K is a Chinese single channel dash camera released in Dec 2020. Blueskysea is known for offering great bang for your buck for their dash cams. Prices are generally affordable and hardware used is decent quality.

The camera uses a Novatek NT96670 processor and Sony STARVIS IMX335 CMOS sensor. The IMX335 is a 5MP sensor which allows for native 2K recording. Both the processor and CMOS sensor are good mid level components.

Video Quality

The Blueskysea B2K records 1440p (Quad HD) video at 30fps with an average bitrate of 16.5 Mbps. Video quality during the day is good and night quality is above average. Video quality is an improvement over the popular Blueskysea B1W but not as good as the more expensive B4K released at the same time.

While a 4K recording option exists for the B4K, this is not true 4K but rather interpolated 4K. We suggest sticking with the 1440p recording resolution since file sizes are smaller and video quality is the same.


The camera has a 1.5″ screen, g-sensor but does not have GPS which helps keep the price down. The camera comes with WiFi and has apps for Android and iOS (KaKaOK). Unfortunately these apps are average with some owners complaining of connectivity issues. Since the B2K has a screen and can be setup right on the dash cam, this may not be a deal-breaker for some.

The B2K provides buffered parking mode if you hardwire the dash cam to your vehicle (optional hardwire kit required) making this one of the lowest priced cams with this option. Another great positive is that the camera comes with audio and screen error notifications. Most dash cams still only provide screen error notifications which can easily be missed by the driver.

The camera comes with both a suction and adhesive mount. The camera can swivel 360° to record interactions at your side windows (i.e. police traffic stop). The B2K is a small camera at 50 x 46 x 43mm however the form factor is not as discreet as wedge cameras or even the popular cylindrical style of the Blueskysea B1W. Overall build quality is good.


Blueskysea appears is very responsive to questions and provides good support. They also provide firmware updates unlike many other Chinese brands, which is a positive as well. The B2K comes with an 18 month warranty if you register the dash cam with them. This is better than many other dash cams.
