Two Seperate Systems With Different Users

Hello. I have a construction business and use one system at my shop and monitor it with the app, no problem. I also bought another system to install at one of our jobsites with cameras, entry, motion etc.

I see both locations on the app. However, I would like to grant access to my client for the jobsite system only. Is there a way for me to provide them with login information just for the jobsite camera so they are able to view cameras, arm/disarm, receive alerts etc WITHOUT them having access to my system at my business?
