The product came in standard packaging with no visible damage. Connected to my PoE camera, no joy. Waited a few weeks to start diagnosing the problem to determine if it was the chamber or the injector and found it was the injector. The voltage on cores 4.5 and 7.8 is not measured. Requested and received a refund. I don't know if I will buy this brand again or choose a different one.
