Fresh off of failing to get DHS to change national video surveillance regulations, Viakoo's marketing guy is now learning about PoE.
It takes him 5 minutes to explain this basic concept:
Many switches do not provide sufficient PoE power for powering IP cameras, especially when there are lots of IP cameras connected and they consume a lot of power each (IR, PTZ, etc.). In such cases, camera connections can randomly disconnect causing problems, something we addressed years ago in PoE Power Problems.
Here is his video:
What is interesting and disappointing is that he never clearly explains how Viakoo specifically determines that the problem is due to PoE power overload.
