Terrible system. The cameras have good video but no feature for control. Cameras talk at high volume and no way to lower or mute. Motion sensor at full sensitivity so that a fly passing by will trigger an event. A spotlight with no way to prevent tied to motion sensor. Hooking cameras to the wifi computer could never accomplish because programming got caught in vicious "search for cameras" "do you see cameras working" ... answer yes camera working takes you back to cameras search .. over n over
