Hey

I am looking to set up a wireless lan network for the single purpose of having pictures taken at our shipping docks wirelessly downloaded into our files back at the office. I was thinking of this setup.

camera>repeater(dock)>repeater(los to office)>long range wifi antenna>switch>PC.

Any input to improve or suggestions for what products would be very welcome

PC -> wired network -> building-to-building point to point WIFI if required -> wired network -> camera. You have to get power to the camera, use POE for data and network.
What distance(s) have to be covered in the office building and the manufacturing building?

it is all in the same large building perhaps 120yds from the office to the docks and the cameras are hand held we plan to use wifi enabled sd cards I believe eyefi is the brand name.

Unless you absolutely know those eyefi cards work right now...they won't. "Know" as in directly tested, camera to PC.
I was a long time user and fan of Eye-Fi. They worked great. Until they sold out to Ricoh. Then, they worked, sort of.
Later...they don't work at all.

And even if they do, you will NOT get 120 yards range out of them. Not even with direct line of sight in perfect conditions.

If you can get them to work at all, and if there is a WiFi bridge right near each camera...this may sort of work.

Another feature that Eye-Fi/Ricoh removed was "endless mode". As in...the card kept a log of which files it had already transferred, and deleted those files as time went on.
Later, you have to manually erase the cards.

Idiots.

You really need to talk to someone that specializes in CCTV. You want commercial quality hardware eyefi is not a solution I would recommend to any business owner.

Ok so I am bored tonight so I decided to dig around the FCC site to see what the output power of those eyefi cards is. There are a couple of models but I looked at the newest.

From what I can tell those device put out 10miliwatts of power. Maybe I am reading this wrong and there is a antenna or something I am missing.

The legal maximum power is 1000mw and most routers tend to try to get as close to that as they can. Some phones to save battery power run at 250mw. I have never seen a device that is that low before...then again they did somehow cram it into as sd ram enclosure.

I am going to bet you are going to have massive issue going even across most rooms with that low of power output.

When eye-fi was working 100%, back in the old days....line of sight in the same room was about as good as it got.
It would mostly sort of connect and work 30 feet away, through a single outside house wall.

Anything more than that, nada.

There's only so much antenna you can jam into half an SD card.
And it definitely eats battery power from the camera.
