Not reliable. Missed vandalism. Ruins SD cards. Events glitching. SD cards glitching. Notifications messed up. Tons of manually recorded videos don't save right and are unreadable trash. App constantly crashes. Does not detect people riding bikes as people. Device offline errors on and off. My internet went out once and came back on but the cameras wouldn't connect again until the next day. I'm glad that there is a free service now because the paid service isn't ready. It is way too unreliable.
