XProtect Essential Event Names Issue

In XProtect Essential 2016 R3, I’m configuring a six-camera system. I want to use the cameras’ built-in motion detection, but after setting that up on the first camera, I could not get XProtect to accept any further event definitions. I kept getting the useless message, “One or more settings are invalid.”

The problem, as it turns out, is that even though I’m working on camera 2, by default, XProtect names the event “Motion start on camera 1.” The message should read, “Event name is already in use. Please choose another name.”

Once I changed the name to “Motion start on camera 2, I was able to save the event.
