This is kind of a basic question but I am asking about installations of high camera count (300+ for example). I know that there are usually a handful of VMSes that support "unlimited" camera counts to choose from.
I find however that a lot of integrators claim that they simply purchase multiple NVRs and somehow link them together. Is this possible? will this approach have any drawback or feature limitations?
I hope my questions isn't unclear or really basic.
Thanks
