Power over Ethernet (PoE) for outdoor displays

"Since it is not uncommon for quick service restaurants to shut down all their lights after hours, for many northern and mountain locations it may be required that the outdoor display start up and operate after it has been frozen to -40°F for several hours. For these reasons, it is critical that outdoor displays be equipped with internal heating elements that will insure that the LCD stays within its normal operating limits in low ambient temperatures. At a minimum, electric heaters require 60 watts of power to heat up a 15” display enclosure from -40°F and keep it warm enough to operate properly."
