Newer Dahua PoE Switches Provides Long-Distance (250 M / 820 ') PoE Transmission

We are thinking of using these on a job, can anyone verify these distances? Specific model DH-PFS4218-16ET-240


I wonder if this is only with their cameras?

Is this something IPVM would want to test/review?

Yes, and Hikvision is making long-distance PoE claims as well so it is something we will test.
