There are some restrictions: cameras are not typically installed in areas where there is a "reasonable [[expectation of privacy]]", such as bathrooms, gym locker areas, and private offices. Cameras are generally acceptable in parking lots, cafeterias, and supply rooms.

==== In private and public places ====
Many homeowners choose to install CCTV systems either inside or outside their own homes, sometimes both. Modern CCTV systems can be monitored through mobile phone apps with internet coverage. Some systems also provide motion detection, so when movement is detected, an alert can be sent to a phone.<ref name="cnet">{{cite web |last1=Wollerton |first1=Megan |title=Turn an old phone into a security camera in 3 steps.
