i cannot find much info online. does POE+ (802.3at) has the same max distance (100m) as normal POE (802.3af)? i need to install a POE+ cam 600 feet away from house and was hoping it would work with 1 POE+ extender.

And you may not find much regarding that because of variations in application will determine that max distance.

When compared to POE (802.3af), POE+ (802.3at) allows for more current, in Watts, to be available from the power source to the powered device on a per port basis. I think the figure is roughly an increase from 15.4W to 25.5W. When any form of POE is provided over UTP, the conductor gauge & material , device current draw, distance to the powered device from the power source and allowable voltage drop will determine the max distance.

This $70 unit is outdoor-rated and claims to be able add 100m of POE/POE+ Ethernet for a total of 200m / 656 feet ==>> here.

I cannot attest to it's reliability or operation.

Thank you. nothing to lose in trying. i also hope somebody can chime in with experiences.

If you are going to use a PTZ that is far away from your recorder, think of powering it locally and using a wireless antenna like the ubiquity nano stations to transfer data. They are about 70 bucks a piece on amazon and will transmit up to 10 miles

i love unifi gear, and wish i had power at the install location. the install location is in the middle of a meadow. the only electrical is at the house......approx 600' away unfortunately.

If the OP has decent LOS, great idea considering NC could have some lightning (not like yours in FL). I love those Ubiquiti's!
BTW, these below are 5GHz Locos @ $49 each. I have successfully used the higher power $70 NSM (non-Loco) 2.4GHz out in the boonies where there was less 2.4 crowding AND more vegetation/poorer LOS to punch through.

You could set up a solar panel and a couple of batteries. For a 24v PTZ and the PoE injector needed for the nano station, I can't imagine that you would need to much power. I know that researching this would probably be the right answer, and everyone on here is going to go against this, but I would start with 2 deep cycle batteries, one or two good solar panels and a charging kit. Build a little vented but waterproof box for everything and see what happens. This may require some cheap beer in cans to execute properly.
