Plan home CCTV around a clear purpose, proportionate views and controlled access. More cameras or a phone app do not automatically produce useful or responsibly handled footage.
A live CCTV image proves only that a view is available at that moment. A useful recording check must show that the right camera’s footage can be found, played and exported by an authorised person.
Remote CCTV access is an account and network decision. The owner should know who can view footage, which service provides the connection and how access is removed when circumstances change.
CCTV storage depends on the recorded bitrate and duration, not only the camera count. Use a calculation to estimate capacity, then verify actual recording behaviour and usable retention in the installed system.
Prepare a CCTV survey by defining what each view needs to show. Camera quantity follows the purpose, site conditions and evidence requirement; it should not be the first and only decision.
