I understand that the pre-record facility is only applicable if you have no constant recording set up. It seems to work correctly if you just have just Alarm/Motion/IVS.

I Remove and stay only alarm. But the same only 10 seconds is pre recording. I tried reset and start again. The first camera worked. But the next not and the first don't work too . I need a solution or I need change my brand. I send email to dahua but they don't care.
