Specifying the right sized PC/server for VMS software is one of the most important yet difficult decisions in IP video surveillance. In the old days, when recorders were all appliances (i.e., DVRs), this was not a concern. The manufacturer designed and certified that the 'box' would support a specific number of cameras (e.g., 4, 8, 16, etc.). Of course, the increased simplicity came with reduced flexibility for expansion. See our software only VMS vs NVR appliance guide for a comparison of the options.
Now with VMS software being widely deployed on 'regular' PCs/servers, integrators need to properly specify the right ones. If your machine is not powerful enough for your cameras, you can face all sorts of painful issues and difficult to troubleshoot problems. As such, getting this right is important.
The good news is that doing so is fairly straight forward if you follow fundamental guidelines.
