Hello i have an older 4208-p with 4 dahua 4mp ip cameras, set to highest resolution ,30fps, 2tb of storage. I am only getting about 4 days of recordings. Should i be getting more, i feel like it used to record much more, like 2 weeks. I checked the hd and both are functioning, but under the hd space it say 0/980gb for both, i guess its full but im overwriting the files. If i upgrade the harddrives, do i have to reconfigure everything, cameras, settings, network settings? Any help is appreciated thanks
