The Blueskysea B4K 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. The B4K is no exception. It is a true 4K camera for $100 which is an excellent price.
While the B4K is currently being sold as a single channel dash cam, an optional 1080p rear camera can be purchased as well. There is a cube shaped camera (type A) and a tube shaped camera (type B)
The camera uses a Novatek NT96670 processor and Sony STARVIS IMX415 CMOS sensor. These are excellent components and are showing up in can many new 4K dash cams.
Video Quality
The B4K records 2160p (4K) video at 30fps with an average bitrate of 26 Mbps. Video quality during the day is very good and night quality is good. Some of the initial videos from this camera appear to have a bit of stuttering, but this appears to be resolved with the latest firmware.
Note that the B4K records using the newer H.265 HEVC codec instead of the more common H.264 codec. H.265 may not be compatible with older computers or viewing devices which could be a problem when sharing video files with Police or insurance companies. Not a huge issue but something to be aware of.
Features
The camera has a 3.16″ screen, which is wider than most other dash cams. It also has a g-sensor and built in GPS. The camera comes with WiFi and recommends using the Ucam app for Android and iOS. This app is simple but allows settings to be changed and videos to be downloaded. Another strong positive is that the camera comes with audio and screen error notifications.
The B4K provides buffered parking mode if you hardwire the dash cam to your vehicle (optional hardwire kit required). This will record 10 seconds before an event and 20 seconds after. Not many low priced cameras offer buffered parking mode so this is a great feature.
The camera comes with an adhesive mount and cannot swivel to record interactions at the driver or passenger windows. The B4K is a medium sized camera at 91 x 38 x 30mm. Overall build quality is good.
In summary, from a specification perspective, the B4K is packed with features for this price point:
- 4K video
- Capacitor
- GPS
- WiFi
- Buffered parking mode
- Audio error notifications.
Support
Blueskysea appears to be responsive to questions and has adequate support. They also provide firmware updates which is a positive as well. Blueskysea provides a 12 month warranty which can be extended to 18 months if you register the product with them. This is better than the standard 12 month warranty for most dash cams.

Should I Purchase
The Blueskysea B4K is packs a lot of features for $100. 4K video, capacitor, GPS, Wifi, buffered parking mode and audio error alerts at this price range is unheard of.
The rectangular form factor is not as discreet as some other cameras and H.265 encoded videos might be a problem if you have older computer hardware.
