I am looking for someone who can build an ad hoc wireless network that will work with:
a) no internet service
b) no wires from phone to camera
c) allows communication between an iphone/android phones/tablet to 2 of these cameras at the same time: Hiearcool H9R Action Camera 4K Ultra HD 12MP WIFI Sport Cam (https://www.amazon.com/gp/product/B0762KLY56/ref=od_aui_detailpages00?ie=UTF8&psc=1)
This hardware should be as small as possible since I'm putting it inside a box with other things and I'm trying to limit the "footprint".
The purpose of this network is to allow a phone/tablet app (which I'm going to have created later) to change these cameras settings, control the EVO Gimbals I've purchased, and allow the app's software/GPS to provide instructions to camera and "metadata" for storage purposes. A storage device or something else may also need connection to this network, but I'm not sure at this point.
