Hi @Breidi 

Thanks for posting in our business forum.

Can I configure the TL-SG105PE so it shuts down a port once the usually connected client is disconnected?

 

Usecase:

Outdoor PoE Webcam connected to a specific port.

If an unauthorized person disconnects the Cam, I don't want him to be able to access my network by connecting a laptop to that port. 

Shutdown, physically, no. There is no function like that on this model.

Virtually, you can use a VLAN to separate it but this will separate you from this VLAN as well. I mean the core network and the camera network. VLAN usually creates network like this one: How to configure 802.1Q VLAN on TP-Link Easy Smart/Unmanaged Pro Switches

If you are concerned about this, it is would better to physically lock it up. Or put it high enough where people are not accessible to it.
