Try these folks for low to medium-end applications:
http://www.microtekelectronics.com/  This is the easiest stuff we've
used.

I've also used SmartSight for a number of applications
(www.verint.com) It's more expensive and harder to learn.

Basically, there are two different types of wireless.  The first type
transmits the actual analog video signal at 900mhz, 2.4ghz, or 5.8ghz.
The second type converts the video signal to IP and transmits IP data
wirelessly including PTZ commands if needed.  The 5.8 stuff should
handle your distance with no problem.  You can use repeaters as well
to bounce the signals around obstacles if needed.  Depending on the
equipment, you can have multiple video streams transmitted and
repeated by each transmitter.
