I'm not a professional about DVR and cctvs and don't have much idea about any products. I'm planning to put 32 cctvs in my new office and even thinking of putting multiple screens all over office.But 1 monitor should have all the cctv and other with selected cctv.
For example 1 monitor set up at the gate with the gaurd he can watch only the entrance and the lobby not the other cctvs. And the recording should be done at 1 place only where all the cctvs can be viewed.
I need help to setup this type of dvr with 1 main and 4-5 additional monitors.
