Pretty simple - with a jumpstarter to power the camera we put it out at the target. We also have a wireless router we needed when doing some >500 yard shooting - the router gave us more range on the camera, and we didn't have to switch to an ad-hoc network. The older droid phone we were using is only running Android 2.2 and doesn't have the ad-hoc capability.
We've been using the wireless cam to watch rats in the chicken coop. It is actually quite useful, especially with a smartphone.
