I want to install an uninterruptible power supply for my system. Is there an basic formula to figure how many watts the UPS will need to supprot. Let's say for a 32 channel Elite NVR, 2 16 port switches and 32 cameras. Also, a router and such but these are likely in the noise compared to the other components. I know I can pull the devices out of locked cases and find the wattage rating on the back of them. But I'm hoping this has been figured out already by someone.
I tried to search the support site but I got too many results for my search on 'uninterruptible power supply'.
