For the past few months I have been playing with a number of relays to use in order wake f800pro camera of parking mode and be able to access it from inside(home) via wifi.
I have tried - bluetooth, wifi, xbee and while all would work ok, will either draw to much power or lack on the range I needed, mostly through the walls of the house.
So I decided to use a cheap fob relay, 315 MHz, which frequency do well through walls and draw little power and are cheap(10eur) https://opencircuit.shop/Product/10981/12v-10A-relais-met-315MHz-afstandsbediening
You can just use the key fob to toggle the camera on/off parking mode or you can do a hack with an additional relay base/gateway(connected to the fob) to expose it to a computer or mobile. I have attached some pics with what I did.
For this particular relay, to enable the toggle function you need to solder the two terminals besides T as in the picture bellow.
Next, I will work on scripts to do the nightly file backup from camera to NAS and I will update this thread if anyone interested.
