These cameras are terrible, the app CONSTANTLY crashes and fails... cameras mysteriously malfunction simultaneously, and replacement cameras often come defective out of the box... not to mention that customer service is a joke. They have about 5 general responses no mater what you say... and have nothing more to offer than replacing cameras with the same ones, creating a never ending cycle of shipping and reciving cameras from customer service and always having at least 1 or 2 cameras out.
