My use case is for security camera installations. I need to interconnect several remote locations into a central monitoring station. Right now, I'm using pools of copper wired connections, all linked together using fiber optic cables. But I need to replace this fiber optic cabling with wireless. What at the devices that I should be using? What are the popular vendors for these?

3I'd stick with the cabling if possible. – Ignacio Vazquez-Abrams Feb 24 '11 at 08:38

@Ignacio, not always possible. But if it's already in place I think that might make sense. – hookenz Feb 24 '11 at 09:31

2Security via long range wireless? You are aware of just how easily that can be interfered with, aren't you? e.g. A few cm of metal foil over one of the antennas will completely kill the link. – John Gardeniers Feb 24 '11 at 09:54

So would a bit of foil over the lens. – hookenz Feb 24 '11 at 10:46

laser would do the job if you have line of sight – Sirex Feb 24 '11 at 11:37

I have been using this, http://www.ubnt.com/bullet along with good antennas for my wireless links. I prefer using the Bullet + antenna because it gives me far more choices in antennas then a having the radio and antenna built into one unit. I have a 13KM link going with two Bullets and 24dBi antennas.
What exactly you need will depend on what you are trying to do.

1Ubiquity are very good. The bullet's are very stable. You'll also need an access point either from ubiquty or from Mikrotik with a suitable omni antenna. 4km is considered close. I had to do exactly what you're doing once before but used trango at the time. – hookenz Feb 24 '11 at 09:34
