We have several buildings on a 1 acre lot. The others had CAT5 run to them 20 years ago. I have a garage that is 60 feet from the main house with a blindspot I want to cover. I would have one camera to start with, at least until I add a second and then an ALPR there. 
So, to start with I would have a single camera, and I can't imagine more than three there total. I could install a cable, but getting out of the house, and avoiding the paved driveway is a pain. I do have a straight line of site to the garage. Which radio solution would be best for this? Looking at Ubiquiti, they have more options than I know what to do with! M2, M5, Loco, the list seems to go on....Are there other brands to consider?
