Normal Recording: It means that the device will constantly record for any period when Normal is selected. You won’t miss anything, but the constant recording will fill your SD card or hard drive very quickly. Typically, we suggest Motion as a better recording mode for most users.
Motion Detection Recording: The device will only record when it detects something moving in front of a camera. Before setting any of your schedules to Motion, ensure that Motion Detection is properly configured for the channel(s) you want to associate with it.
