Bruce0 0 Posted January 1, 2021 V4,02,R11.85100148,10001,131100, Every day my H.264.DVR goes into update mode and freezes. I dont know where to look for updates or firmware . my dvr is a DM81Z1T. I have been trying for a week now. Where and How do I get my machine running again. I'm 75 and not really that knowledgeable about firmware and how it works I have down loaded a program to put my address in so i can load from my laptop but cant find firmware.
