How to organize the broadcast of DAHUA, Hikvision DVRs on one site in the local network?

Question

CCTV

There are about 10 DVRs, there are also Dahua and Hikvision. It is necessary to arrange for management to view all DVRs on one site in the local network without access to the Internet.

Answer 1

Why the hell do I need one site I don’t understand.
If you want to quickly and free of charge - put smartpss and ivms-4200 in the manual. Native apps from dahi and hic.
If you want long and free - google something like js rtsp player, links to video streams from cameras are in the manual for reg.
If you want long and expensive - google "rtmp camera output to the site" and the previous option requires an additional rtsp-rtmp transcoder.
If you want a long and very expensive - google macroscop (and maybe even Line) and the integration of your regs into this software.

Answer 2

From the free - rtsp player to the site, and the output of streams from regs via the same RTSP.
Most likely you will have to encode / decode the stream
From a paid - tracer
From a more paid, macroscope))
Well, or the same line

Answer 3

Locally install the demo version of Line.
