I haven't tested, but this appears to be (mostly) "Unidentified" and a few LANDesk Remote Control or Remote Management. That makes me wonder if they all are, and whether they are in fact remote console/desktop access to systems.
Is anyone able to clarify what 'these devices' refers to?
port 37777 looks to be commonly used for tcp video streaming
The link takes to a search for devices using port 37777 - TCP cameras.
Obligatory reminder that trying to access one of these devices is a felony (under the CFAA). You probably probably won't be prosecuted, but it's a possibility.
