Arlo Q Plus PoE.

What is the spec for the PoE? I plan to use an injector at the Ethernet switch location.

Arlo Q Plus uses IEEE 802.3at.

Thanks JamesC. There is nothing at all in the documentation supplied with the camera or in the reference material on the Arlo website that tells me the "flavour" of PoE supported. As you are probably aware, 802.3at is known as PoE+ or PoE Plus, whereas PoE generally refers to 802.3af, which is an older version with lower voltage and power. The documentation for the Arlo mentions PoE, but not PoE+, hence my question. I am using a PoE injector that can be configured to send a DC voltage of between 12v and 47v. The 802.3at spec is for the PSE to deliver 50v to 57v at up to 600mA. What PSE sending voltage would you recommend for the Arlo Q Plus camera to operate reliably, with a cable length of about 10m?

WarrenWillis,

I have escalated your question to engineering. I will post an official response as soon as I have more information.

WarrenWillis,

I apologize for the incorrect information above. Escalating this topic to engineering resulted in the following Q&A:

Engineering has confirmed that the Arlo Q+ dongle uses 802.3af Class 0 (12.95W max) and that the actual power draw is ~2.8W.

Q: What is the voltage needed for the Arlo Q Plus PoE adapter?

A [Engineering]: 44VDC – 57VDC is the required voltage range for 802.3af as measured at the PoE switch or PoE injector.

Q: Would passive 24v be enough?

A [Engineering]: Passive 24VDC would not work at all. I don’t recommend the customer use anything but an IEEE compliant 802.3af/802.3at PoE switch or PoE injector.

Q:Can the customer use his injector(13V~47V) for ArloQ ?

“As you are probably aware, 802.3at is known as PoE+ or PoE Plus, whereas PoE generally refers to 802.3af, which is an older version with lower voltage and power.

A [Engineering]: So long as the customer’s PoE switch or injector indicates that it is IEEE 802.3af or 802.3at compliant on the product label or in documentation.
