Q: What shall we do when the mainframe video input interface is different from the camera input interface?

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.
