Hi all. I’ve been using Dahua cams for a 1.5 year now, and I’m pretty happy with this equipment. There is however one thing that is bothering me. I use my cams only with micro SD cards. It makes the system as simple as possible. Every cam is powered by separate 12V UPS, which makes every cam “self sufficient”, even in case of power shortage or network failure. I use motion detection for recording. However there is an option in Record control called Pre-event record. It means the camera is actually recording all the time, 24h/7 days a week, and leaves only moments, when event occurs, plus prerecorded period. And so, the micro SD card is under constant usage, even if nothing is happening. After a year or two, such card is dead no matter what. Now the question: if I set the pre-event recording time to 0 seconds, will the camera stop the process of constant recording? Can someone please confirm that?
