A great article in that even though it did not find a problem with cameras commonly being under-spec'd on their POE requirement, just as importantly alleviates that concern for the most part. I once wondered if manufcaturers were being overly optimistic in their POE requirements.

Solid data. Thanks! A couple of follow-up questions, if you don't mind:

  1. Would a 100M cable materially increase the power consumption?
  2. Would a change in ambient temperature likely affect consumption significantly?
  3. Would there likely be any effect related to the actual data thruput, i.e. less power at 1 FPS vs 30 FPS?

I just asked Avigilon about the H3A camaras 22W consumption and got a response that this can be reached if the heater is on on a very cold environment and the replay is giveing a 12V output to a consumer. In this case you should use a POE+ supplier.

In normal cases a regular POE supplier can be used.

So if camera POE loads are lower than datasheet swag, power field deployment issues are resource related?

POE vodoo, power should not be the challenge.

Byte widget looks nice.
