Which program to choose for viewing video from ip cameras?

Question

CCTV

Actually, you need a free client in which you can add entire DVRs, with a large number of cameras, so that you can make 6 windows (for each monitor), and each window has more than 32 cameras.
At the moment, IVMS 4200 and its other versions are used, and HQ Vides System Management Client from the same manufacturer, but in these programs you cannot give more than 64 cameras for the main window and more than 16 for the additional one, and there are more cameras.
Google did not give much, advise who knows what.
