The cameras are garbage, they don't have the range they claim to have. Unless, your within 20 feet they don't pick up Also I myself along with delivery people walk right by the cameras, and they do not detect you. #2 the cost of the units are ridiculous, If I had any Idea they would be this useless I never would have taken them. I called for support and they had me resetting and rebooting the cameras, to no avail. User's recommendation: do not purchase !
