    Hi everyone. I'm pretty interested in the SJ5000x Elite, precisely to use it as a 60 fps deluxe webcam. Does anybody please have the following information ?
    • Max resolution and framerate in the "PC Camera" mode,
    • Battery autonomy in the "PC Camera" mode (does the USB connection charge the battery or drain it ?),
    • Latency in ms of the "PC Camera" mode,
    • Latency in ms of the live HDMI output.

    Thanks :)

    Hi @mclat

    Not sure about max resolution and framerate on PC camera mode, and battery autonomy either. Or at least not yet.

    What I do know is that you can check bullet points 3 and 4 by filming (actually, video recording) a cellphone timer with the camera in question that is also plugged to your PC or TV,
    and simultaneously video all the screens with another camera.

    The resulting video will have 3 subjects,
    1. The actual timer
    2. The display of the camera taking a video of the timer, and
    3. The PC or TV live feed from the camera in question, connected via USB or HDMI.

    Take a screenshot of this and you will see the differences in time as showed in the displays of the camera and the PC/TV.

    Subtract the numbers and you have the latency in seconds and/or milliseconds.

    Take at least about 5 screenshots to get the average latency.

    Hope this helps. Post your results here so everyone interested would know.

    Cheers!

    Thanks Troy. I actually already know this technique but wanted to have the information before buying the camera.
