Plan is to extend WiFi from inside my house outside approx 600 feet (clear line of sight) to barn and livestock pens which will have multiple WiFi security cameras located there. I will run a cat 6 Ethernet cable from my Asus RT1900-AC router to an outdoor access point located on the outside my house and place 1 or more access points located on the remote end. My goal is to be able to view the WiFi security cameras located on the remote end from the computer in my house. I have been looking at the Ubiquiti product line but not sure which model would have that capability and give me the best result. I am also open to suggestions of a better plan but please keep it in simple terminology. Thanks so much!
