Is there any danger of using these to check ports in a power-over-ethernet (poe) switch?

Only if you have done some crazy hardware alterations or a homicidal arch nemesis.

Will this work for 10Gbase-T connections over cat6a?

It should. Cat6 should pass lower data rates just fine. You'll just get link lights or not.

Will this test if the eithernet port on my camera is working?

It will be able to test Ethernet connection if your device has a network card that transmit the signal.

Does this work on non-gigabit connections as well?

Yes, this adapter is backwards compatible with non-gigabit connections.
