Hi folks. Ive been reading up on the need for surveillance hard drives in an NVR due to the constant writing for live video recording. I was curious if anyone has played with using a normal hdd as a mirror or to archive the footage. I want 16 4MP cameras running 24/7, but with 90 days of footage.. that creates an expensive storage situation. Does anyone have a cost effective solution and is archived footage usually accessible remotely via app or do I need to rdp into the NVR?
