Hi, Would there be any reason not to run a power cable and take of at certain points power for using WiFi repeaters, using this method you should have no signal loss, nor have problem with regulation (LV/MVoltage) 1 repeater placed in a good location may be used for more than 1 camera and as a second consideration WiFI may have other uses for the owner, any long runs use cable when it suits it may be better than running cables due to losses in the cable
