I have not tried this product with PoE cameras or similar. I'm sure they will probably work great for those applications. I tried using these splitters and router injectors. I wanted to install my router high up on the wall in the hallway for better coverage of the whole house. Using this product has more than halved my network speed (even with a Cat6 cable as a connection). It didn't even support 100Mbps. Avoid this if you use it to operate a router or access point that requires 100 Mbit/s or more.
