12V PoE

[buellwinkle 0]

For cameras that use 12V, is it possible to power the camera via the ethernet cable. I was looking at this from Vivotek that I'm assuming gets 12V from a power source, and ethernet, feeds them across a ethernet cable to the camera and then splits it back out so you have ethernet and 12V seperate. I believe Vivotek sells these to sort of emulate PoE for it's non-PoE cameras.

If this is the case, can it power a camera that say uses 11W of power at 12V?

I have a similar kit that was used with a LinkSys WAP.

 

The injector basically sends full 802.3af-compliant 44VDC over the cable, so it can be used with any PoE camera... the splitter at the camera end knocks it back down to 12VDC and spits it out on a standard barrel plug, for non-PoE cameras (or whatever other devices).

 

802.3af states it should provide "up to" 15.4W... so yes, it should be fine to drive an 11W camera... ASSUMING the step-down can handle the just-slightly-under 1A output current.

I recently installed an older non-POE Vivotek with the TP-Link TL-POE10R POE splitter, and it's working fine. The splitter is adjustable for 5, 9, or 12Vdc, and draws about 1W idle with nothing connected to it (9W with the camera in my case). I run it from my POE switch.

 

This is just the camera end, and runs about $18 shipped from newegg. For about the price of the Vivotek pair, you could get an inexpensive POE switch and the TP-Link splitter, and have room to grow.
