Live Feed of All Cameras On Tv

Hi all, I just joined and tried to find this answer and could not. I bought a security system for my office and cameras. I also just bought a Ringo Pro Doorbell and Cameras from my house. Is there any way I can set up a separate tv to see all my cameras at one time? I heard about the echo dot and firestick but that is 1 camera at a time I thought. I attached a general picture of what I am looking to have permanently on a tv in my office. I appreciate the help!
