IP Camera Power Consumption Guide

Author: Derek Ward, Published on Dec 24, 2014

How much power an IP camera consumes is important, especially since most PoE switches have limited power budget and do not support max 15W to all cameras, making PoE Power Problems commonplace.

However, these problems can be mitigated by measuring power usage.

In this guide, we:

  • Measure power consumption from 35+ different IP cameras from over 10 manufacturers.
  • Compare power consumed to what the manufacturer specifies.
  • Contrast power consumption for integrated IR cameras with IR illuminators on vs off.
  • View the impact multiple streams have on power consumption.
  • Examine issues in the boot up process for power consumption.
  • Offer alternative tools to measure power consumption.

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.

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.

A great article !!

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.
