How to identify the nodes in the LAN that connect to the DVR?

Question

D-Link

Hello!
The task would be easy if the traffic went through the gateway or if it was a computer. In this case, it would be possible to install some program for traffic analysis. There are no related functions on the DVR itself. The only thing that comes to my mind is to analyze the traffic through the D-Link DGS-1210-52/ME switch. But how to do that?

Is this a registrar where there are no such functions? We need to look better - these are the primary functions related to security - there should be in the logs.
