2.4ghz video units
From 50mW to 1Watt

www.jasco.co.za
http://www.jasco.co.za have electronic engineers that can develop radio systems on any frequency. They did systems on 1Ghz for the mines(illegally) in South-Africa, a frequency used for missile tracking in the northern hemisphere. 1Ghz will give better LOS throughput that 2.4ghz or 1.2ghz and cut down on spectrum pollution in the ISM bands.
