Ive been using piper for 3 weeks now and I can say that its an excellent system for the price, many users seem to have connection problems, but Ive been testing mine and it never failed to notify me with the motion detection or door sensor, I live in a 1000sqf apartment and piper never failed, I guess a good internet connection and a excellent router will do the job, as for the camera quality... Yes its not excellent but your not using the camera to make movies... Its just to see whats going on, I would have given 5 stars if the camera quality was better but I still recommend the unit 100%
