I tested out one of the cameras, and I was impressed by its quality and range. However, I noticed that I am quite limited on where I can place them. With their standard equipment, they can only me attached to vertical surfaces. Additionally, they aren't supposed to be placed higher than ten feet from the ground to optimize their motion detection. I also want them to cover several areas with each one being in range of at least one of the other cameras. As I only have three plus a doorbell camera, that really limits my options unless I order another couple of cameras--and while this brand was quite affordable, the cameras aren't exactly cheap.
I'm going to spend a little while tomorrow figuring out this puzzle.
