CAN I INSTALL PASTEL CCTV ON ONE NETWORK

Is it possible for me to create a workgroup network for cctv on a current Pastel workgroup network running win95/98 workstations? Currently the Pastel network has 10 workstations and a 20 port hub. Can i use the same hub for cctv which needs an extra 6 workstations for now but will expand in the near future? I was thinking of buying a new bigger hub.
