quick question for the pro technicians, I have dahua cams with a microsd card inside, and also a nvr with hard disk in backup if ever the microsd is defective, my question is what to do when I watch from my cell with the DMSS app so that it is the nvr which reads the video notifications and not the microsd card because I find that it often waves from the card, according to your experience reading from the nvr would you be better? and dsl for English I take a translator I hope I explained well
