I have a Synology DS918+ with 6 cameras. I had a porch pirate steal a package and couldn't see his face clearly because when originally installed, I didnt configure the cameras for high definition. I have increased the definition of the cameras but now when navigating through my files, it is very laggy. What recommendations do you all have for me? Is the DS918+ too weak for 6 cameras? should I add more ram? the resource monitor shows cpu at 6% and ram at 17%. I currently have 4- 4TB drives in an SHR (one volume). should I create two separate volumes (2 drives in raid 1 configuration for data and another 2 drives in raid 1 configuration for my cameras)?
