SJ4000 action camera powered by Novatek NT96650 processor

    Not so long ago, an interesting, in my opinion, action camera called SJ4000 appeared on the market, which externally copies the famous GoPro cameras. It is clear that this model is incorrect to compare with GoPro in the quality of materials and iron, since the price difference is fivefold. Accordingly, the quality is different. But still it’s interesting to see what good manufacturers SJ4000 spied on a well-known brand. In addition, the accessory kit for this camera is very rich and partially compatible with GoPro. In order to show the maximum potential of this model as objectively as possible, he made more various filming at different times of the day. But first things first.

    > Iron


    The Novatek NT96650 processor installed in the camera easily processes video with a resolution of 1920 * 1080 at a frequency of 30fps without failures and overheating.
    This processor was released in 2013, and at that time was the best in terms of price and quality. Many bestsellers among DVRs are equipped with this processor.

    The camera can shoot:
    1) Video in modes: 1080p_30k / s, 720p_60k / s, 480p_60k / s (the camera supports only 30fps in hardware, and 60fps in the video is obtained with software frame duplication: two identical frames instead of one).
    2) Photos with a resolution of 5MP to 12MP.

    > Interface and software


    The camera interface is simplified to minimalism: in front - on / off button; mode switching; top - OK-start / end of shooting; side - volume-zoom-transition menu. All buttons are intuitive and easily searched blindly.



    When connected to a PC, the camera asks about the operating mode, either as a flash drive or as a web camera.
    I will note some operating modes and functions: 1) The mode of cyclic video recording 3/5/10 minutes and dubbing; 2) Photo timer 2sec / 5sec / 10sec; 3) CAR DV mode (DVR in the car: the camera can start recording when the charger is connected and stop after); 4) Photos during recording.



    > Shooting in various modes


    A fixed focal length lens has a viewing angle of 170 °. For video shooting, a resolution range from 640 * 480 to 1920 * 1080 is available.
    SJ1000 can take photos with a resolution of 12 megapixels. Pictures are obtained of medium quality, with some spatial distortion and reduced sharpness at the edges.
