I have used both the 4-port and 2-port versions of the product with no limitations or loss of performance from my poe switches. I currently have 2 ports running a Unifi Nano hotspot and a 4k IP camera, both Poe in 2 different locations. I am running 4 ports for 4.5MP fisheye IP cameras from a poe port on the switch. No signal loss or power issues.
