Trying to power 2 HD-TVI cameras 800 ft away from my home office.
The wall mounted adapter provides 12v DC at 1 amp. I am looking for a good solution at the lowest possible cost.
There are already some great answers posted for a 5v camera. This, however, involves at least 2 cameras at 12v and the wire will run in the ground.
It seems Ignacio Vazquez-Abrams and others have simple solutions by running 24v or 48v and a regulator module just before it attaches to the camera. The best answer does seem to be: distribute higher voltage and use regulators at the far end. I am not sure how to do that or what to use or if it will work?
10 gauge wire would likely solve the problem, but I would like to use the 20 gauge wire I already have.
There is not power 800 ft away at the location being monitered.
