Hi @Vinny. I require a minimum operational range of 10km with video feedback. I've selected the MPU5 from Persistent Systems for this application. Since it is portable and can be carried on the body.

Pair it with a Microhard HP900. It may be possible to achieve 480p up to 80km away, but that's just an assumption.
