Don’t take their word for it. Get a cheap continuity type cable checker. You’ll be glad you did. Sometimes, a punch down doesn’t go well or they mistakenly used B instead of A, etc. Really need a patch panel. Will save a lot of frustration. Don’t forget to get the tool to punch down. I’d buy some short ethernet cables to make the connections in the panel, too much trouble to make them and I’m prone to make errors. Personally, I’d go with a separate switch for the POE connections. This will enable a separate LAN for the cameras, if needed.
