    Main Features:

    Ultra HD, Real 4K Car Dash Camera】The Blueskysea B4K is a premium quality, full 4K resolution car dash camera that has been designed for drivers. It utilizes the latest generation Sony 8MP IMX415 low light capable image sensor to capture highly detailed and clear images of license plates and road signs at Ultra HD resolution (4K-3840 x 2160) at 30 frames per second. A 120° ultra-wide-angle A+ quality lens captures every important detail of what happens in front of the car. The WDR function records a Wider Dynamic Range of light levels so that details normally hidden in the shadows are recorded.

    Buffered Parking Mode】Compared to other driving recorders, the Blueskysea B4K records not only accident results but also the lead up to the impact. When an event is detected, a 30-second video (10 seconds before and 20 seconds after the impact) will be saved and protected from overwriting.
    No built-in battery inside the dashcam unit. And an optional hardwire kit, which can switch the camera into parking mode when it detects that the car is parked, is available separately.

    3.16'' IPS Screen】The Blueskysea B4K has an integrated 3.16'' ultra-wide screen IPS monitor which clearly displays dual front and rear video views (rear camera is optional).

    Built-in GPS】With a built-in GPS receiver, the car camera logs the current speed and GPS location with an optional video overlay and will automatically synchronize the clock with GPS satellite time. What’s more, the route recorded by GPS is displayed on Google maps during video playback.

    Smart APP Control & Built-in WiFi】The Blueskysea B4K has built-in Wi-Fi with an easy connection to your smartphone app. You can synchronize the files on the car camera to your phone through the "Ucam" app. Video files can be downloaded to a smartphone and shared with social media.

    Loop Recording, G-Sensor protection & 256GB Max. Storage】Seamless loop recording overwrites the oldest footage with the newest upon reaching card capacity. A configurable sensitivity G-sensor auto-detects sudden shake/impact events and protects the event footage to prevent overwrite. The car camera supports a maximum microSD card size of 256GB, thus ensuring almost 24 hours of recording time before overwriting the oldest video footage. In addition to the above, this dashcam has many more basic functions such as time-lapse recording, audio recording, and time+date+speed video watermarks, thus making it an excellent choice for your driving recorder.
