Although CCTV is typically more noticeable in commercial settings where it is used to monitor comings and goings and even, in some cases, staff productivity as well as providing a security measure, it can be used in homes, too.

As such, you will tend to see only a few CCTV cameras in operation in domestic settings, usually focusing on the main entrance.
