gotime, thanks for the info. So you pay the $15 per month for them to monitor it, as well as an additional fee for the ability to control the system remotely with your phone? What is the sum total per month? It is very tempting to go with the Fortress system which is totally free after the initial purchase (and batteries of course). But is not monitored, rather, it just calls you or a designated number.
btg3, I don't know much about the system you are after, but knowing a decent amount about cameras (enough to be dangerous anyway), anything over 60-degrees is starting to get into fisheye territory, which are usually much more expensive, and get a lot of distortion around the edges of the frame. Kind of like when you look out through the peep hole of a door, the peripherals are pretty useless. It might be worth considering an additional camera or two, placed strategically to still cover the same viewing area? Just a thought. This would also afford viewing of objects farther away in more clarity. With wide angle, things may be much closer than they appear!
