Review: Good choice for cctv, voip - Powered a POE splitter for powering a security camera. Works as expected. Was working for a month 24/7 until I turned it off. Also compatible with IP Phone with PoE. I think it is compatible with most poe devices, but I have only limited set for actual verification. Recommend to buy for different use cases. PS I didnt verify a gigabit connection, only 100mbit devices used.
