Update: Camera 1 no longer activated by ANY type of movement. Camera 2 works sometimes, sometimes not. Unreliable junk. DO NOT BUY, you will be disappointed. Cameras go offline randomly, for no apparent reason (not attributable to power, cable or wifi disruption). To get back online, you have to physically access the camera. If you want a system to monitor a vacation home or for security, buy something else. Customer support sends auto-generated troubleshooting links that do not help.
