When would system need to be pluralized?
Say you offer two products that serve the same function. Do you offer two systems or one system?
To try and give an example...
I have an integrated facial recognition system built into the camera. Few years passed and I developed a new camera that also has my facial recognition. I offer both options. Would I say:
"My system integrates facial recognition..." or "My systems integrate facial recognition..."
Is there a rule for determining something like this? By sound I lean towards it being a singular system. My colleague believes it needs to be plural.
