HDHR PoE?

Post by julesism »

Hello. I'm thinking about powering my HDHR devices via PoE using the two items below. Any feedback would be appreciated (unsupported, too much or too less power, risk of bricking device, etc):

Only the extend is 12V the devices you mentionedcl are all 5V so you would fry your device.

The quatros are usually your best bet but not at 12V. Note that the devices are very finicky for proper voltage and low noise and many converters don't do a good job.

You might look at something like this: https://adafru.it/3239

It takes 802.3af PoE and offers 5, 9, or 12V selectable output with a barrel jack. If the diameters are off, I'm sure you can find something else that's similar.

Thanks for all the replies. I recently cleaned up my network closet and I'm trying to get rid of excess wires and power adapters where I can. I have a Procurve 24port PoE switch. I do not want to try this if there is a risk of messing up the HDHRs.

I found this item which says its 5V 2.4A and comes with the adapters:

The 2.1/5.5mm plug will work for the HDHR4-2US and the HDHR3-US.

The HDHR5 uses a 4mm OD plug.
