I have been working on some wireless CCTV solutions and have found some neat kit with application in EAA. First, I discovered these outdoor 'point to point units' - range up to 2Km!
Easy to set up. Far more powerful than domestic wireless extender solutions. Completely independent of your Home WAN network and it's frailties. Hence no interference. But require 240v (110v in USA) to power it's Power over Ethernet (POE) local cabling. But note the HD resolution limit.
If you need remote 240v AC (or 110v in USA) power at the scope for these, simply connect a 12v/240v DC/AC (or in USA 12v/110v) Inverter that will step up power. One joy is that you can then use the equivalent of mains power for scope and camera too (e.g. using their AC/DC adapters). This unit is small and works great with most 12v batteries common in the astro world. It's a much more reliable way of providing power (e.g. using your cameras/mini-computer or other equipment AC/DC adapters). It outputs 240v/300w AC (from a 12v battery) and I am confident would distribute steady power far better through a devices AC/DC adapter than battery alone. You need POE (24v or 48v) for the type of wireless extender described.
This specific kit is obviously designed for the UK (240v) market, but I am sure there are USA equivants. The really clever thing about POE is both power and data flow down a single cable.
