Works excellently as a system. Care needed with placement of cameras as range for picking up and recoding a human is 2 to 3 metres. This range is affected significantly by backlight to the subject .ie someone coming out of bright light onto a verandah or under an awning. I would like to be able to run the spotlight during the day to help resolve this issue. Unfortunately this is not possible. Easy setup and very usable app to control system.
