    Appendix 1: Common Questions and Answers (QA) for MDVR


    Q: What shall we do when the mainframe video input interface is different from the camera input interface?
    A: a 4-pin interface is used for the vehicle device. BNC interface or air interface is used for the camera. If inconsistency is found, please use an adapter or connect it to a standard line defined as the line sequence for the vehicle device.

    Q: What shall we do if recording is unavailable even when the device is powered on and HDD is installed?
    A: 1. Check that the HDD is formatted after HDD is installed and HDD without formatting cannot be used. From the Main Menu-Management Tool-Formatting, format the newly-installed HDD.
    2. Check if the record channel is off or if timing record is set. Recording is unavailable when it is not within the recording time frame.
    3. Check if the HDD is properly contacted, and the HDD on the front panel is lit up.
