I'm looking to set up a temporary point to point system at a long distance range.
Ideally, there would be 2 cameras; one pointed right at the target, the second one set back few (several) yards back to catch a wider angle (flyers, wind corrections, etc.).
On the receiving end, there would need to be another 12VDC system with a router, maybe even an NVR and obviously a display or 2 (PC or tablets).

Working distance would be up to 2 miles initially, stretching to 5 Km in the future.
