I've recently installed a TL-PA9020 kit in my house.  I have an (100VAC) electrical line running from the house to a small shed outdoors on which the TL-PA9020P adapter seems to work well.  I would like to create an access point on (or in) the shed which can be used by a video camera about 75 ft. from the shed in one direction and also a Wifi interface board in a Generac backup generator about 50 ft. in the opposite direction.
 

Is the EAP225-Outdoor access point the best solution for this scenario?  This access point will be only lightly and infrequently used, but I want it to be highly dependable during fairly lengthy periods (several weeks) when we're absent from the home.
