This set up is cheaper than a high end spotting scope. Down side is the set up time.
the pic shows the system set up in my garage as reference.
Hd full 1080 dig camcorder, plugged into a wireless transmitter which has the capability beaming the signal to the receiver which is plugged into a lap top 1k away.
Lap top has the software to record/edit/cut rewind etc. it records at the camcorder and at the lap top.
Believe it or not, this set up isn't that expensive. the most expensive components were the trans/receiver which are good out to 1 mile.
I only use this set up when Im alone sending them to distance out in the desert valley out to about 1200ish.
Just a thought.
