WiFi bridge

[J B]

I thought PoE was 'power over ethernet' meaning no other power supply needed

Yes, but it`s a wifi bridge, so you need power at both ends

So rather then having a seperate power cable the power comes on the cat cable that is taking the signal to a camera. / wifi access point or whatever
Supose if you just wanted a camera at the shed which was connected by cat5 you could feed it from the house end, but I guess most folk would want a wifi service as well if they had gone to the bother of running a cable.
I think you can only run 1 device on a cat5 POE

Two of these, they will either preconfigure them if you wish, or you can do that but yourself.
I fitted one on my house, one on my grainstore , put an old router in there, now got 30mbps broadband there.
Shopping list.

A pair of ptp bridge units.(running mine on the poe injector it came with)
A pair of mounts.
A router.
Ethernet cable to plug router in to the ptp.
You also need a cable from Poe injector in the barn to the router if that's how you wish to do it. Or plug the camera straight into the injector ethernet port to save the router, but while you're at it you may as well set up the WiFi there.
Couple hundred quid all in.

I use these, but for wifi links go for the 5ghz version, less chance of interference.
I have one on the house chimney set as an access point then 3 others on sheds set as clients each facing the house one. Furthest is about 200m distance, though they are supposed to be good for a few miles if line of sight is possible.

Quite a few things, like my security camera, don't support 5ghz though, and 5ghz doesn't go as far as 2.4ghz as an extender.

Yes you are correct, 2.4ghz is better at going round corners or through walls plus if you want to broadcast wifi across the yard then the ones you have are better.
But for a dedicated wireless link between buildings and doing nothing else then the 5ghz has an edge, more so if you are pushing for longer distances, due to cleaner frequencies. No reason you couldn't plug in a 2.4ghz wifi broadcast point into the extender at the far end though if needed though.

I have one of these on the gable end of the house which is a dedicated 5ghz link https://www.solwise.co.uk/wireless-outdoor-bridging-el-ens500-ac.html to this https://www.solwise.co.uk/wireless-outdoor-bridging-el-ens620ext.html which is my access point on the gable end of the tallest barn in the yard 150m away, the access point runs both 2.4 and 5 ghz wireless which serves my needs for cameras (2.4ghz) and general data etc (2.4/5ghz), all the AP end of the bridge needs is a 240v supply for the PoE injector. Solwise were superb to deal with, and my whole yard is covered.
