hello everyone, weird problem today .. I was watching how to set my alarm sign and suddenly I lose the image on my camera ?? I am trying to reconnect with my camera but it cannot be found ?? not via ip, not via SADP not via hikvision player .. nothing, camera continues to follow and records on the sd card but i can't do anything anymore, not via internet, not via pc, not via nvr .. it once has something like that experienced? there is no reset button on this camera, so I'm at my wits' end?
