How to hide a device from the network in Windows 7?

Question

Computer networks

Hello, friends!
Please tell me how to solve the following problem:
We recently installed ip-video surveillance in the office, after which we see the following picture in the "Network" section of Windows 7:
How can we remove IP cameras from this folder? It makes no sense to change their IP addresses by moving them to another subnet, because you will have to specify an IP from this subnet as an alias to yourself in order to be able to connect to the DVR, the same with VLANs. Even the option of walking around the office and manually deleting everything unnecessary on each computer would have been suitable, but nothing like this was found in Windows either.

Answer 1

It is pointless to change their IP addresses by moving them to another subnet

Not pointless, but correct.

The correct solution is to put the cameras in a separate subnet (respectively, in a separate Vlan), open access to this subnet on the gateway, only from the necessary IPs.
That's right, not from the side of "camera icons in Windows", but from the side of network planning and network security.

Answer 2

If you do not look at how it is correct, what was indicated above, namely to hide - disable upnp and nat at the same time in the cameras, they will disappear from the network environment and will be available only via ip
